|May-25-08|| ||littlefermat: Annotations done by Neil R. Brennen:
1.e4 e5 2.Nf3 Nc6 3.Bb5 Nf6 4.0-0 Nxe4 5.d4 Be7 6.Qe2 Nd6 7.Bxc6 bxc6 8.dxe5 Nb7 9.Nd4 0-0 10.Nf5 10. Nc3, as played in the seventh game of the series, or 10. b3, followed by Bb2, as adopted by Showalter in the ninth game of his match with Kemeny, is much superior. The text move enables Black to exchange his Queen bishop for a well-developed piece. 10...d5 11.Qg4 Bxf5 12.Qxf5 Qc8 An exchange of Queens would seem dangerous for Black on account of his double c-pawn. 13.Qxc8 Raxc8 14.Be3 c5 15.Nd2 a5 To play 15. ...d4 or 15. ...c4 would have been bad. The former move would have given White a chance to bring his knight into action, while ...c4 would have been answered with b3 or c3. 16.f4 f5 17.Rfd1 Rfd8 18.b3 Kf7 19.Kf1 Ke6 20.Nf3 h6 21.c3 Rg8 22.h4 Nd8 A complicated position, both sides striving for the attack. White intends to advance the b-pawn in order to follow up with Nd4, while Black has the ...g5 move in view, which would result in the winning of White's e-pawn. Both plays seem to be very promising, but White, by moving h5, can easily prevent Black's continuation, while Black apparently has no means to stop the advance of White's b-pawn, especially since White can make the a3 preparatory move. The move selected by Black, 22. ...Nd8, is probably the best for the attack as well as for the defense, for he can continue ...Nf7 as well as ...Nc6, yet it is hardly satisfactory. It should be mentioned that Black could not play ...g5 at once, for the game would proceed as follows: 22...g5 23.hxg5 hxg5 24.fxg5 f4 25.Bxf4 Rcf8 26.g3 Bxg5 27.Nxg5+ Rxg5 28.Ke2 and White remains a pawn ahead. 23.b4 As pointed out above, White should have played 23. h5 first; he also might have made the preparatory move 23. a3. The continuation White selected is quite ingenious, yet it would have been much better to delay it for a few moves.
|May-25-08|| ||littlefermat: 23...axb4 24.cxb4 cxb4 25.Nd4+ Kd7 26.Nxf5 c6 27.Nxe7 White evidently had the Bc5+ and Bxb4 continuation in view, and he abandoned the capture of Black's b-pawn on account of Black's probably reply, ...c5. Black's passed d-pawn and c-pawn would become very threatening indeed. White, however, should have taken this in consideration before he captured the bishop. He should have played 27. Rac1 instead of 27. Nxe7. White then threatens Rxd5+, followed by Rxc8 and Nxe7+, etc. Black apparently had no better reply than 27. ...Nb7, which would enable White to continue with Rc2 and Rdc1; it would seem quite difficult for Black to stand the pressure the doubled rooks would exert on the c-pawn, which cannot be advanced easily on account of Nxe7, followed by Bxc5+. It seems that White at this stage of the game did not display the best position judgment. He should have made the c-pawn the target of his attack and not the b-pawn, which was of comparatively little value anyhow. Even should White succeed in winning it, Black still remains with two passed pawns. 27...Kxe7 28.Bc5+ Ke6 29.Kf2 g5 White exhausted his attack without making much headway. The advance of Black's g-pawn becomes now very threatening. White cannot maintain the f-pawn, even should he move g3. Black would continue ...gxf4, followed by ...Rg4 and ...Kf5, [and] eventually ...Ne6 winning the f-pawn. 30.hxg5 hxg5 31.Rh1 Probably as good a move as he had at his disposal. Black in nearly every variation will win the e-pawn and f-pawn, and he will obtain the superior endgame on account of his strength on the queenside. 31...gxf4 32.Rh6+ Kf5 33.Re1 Rg6 34.Rh8 34. Rxg6, followed by e6, was much superior. Black then had hardly a better play than ...Nb7. White then can continue Bxb4, followed by Bd2. It seems it would not have been difficult for White to draw the game, even should he be obliged to sacrifice the bishop in order to stop the advanced pawns. 34...Ra8|
|May-25-08|| ||littlefermat: 35 Re2 Ne6 Brilliant and sound play, though it must be admitted that Black was forced to it. The sacrifice of the exchange leaves Black with strong pawns on the queenside, and it rests with White to fight for a draw. 36.Rxa8 Nxc5 37.Rf8+ Ke6 38.Kf3 Nd3 39.Rf6+ He could not play 38. Re8+ in order to save the pawn. Black would have replied ...Kd7, attacking the rook and threatening ...Rg3 mate. 39...Rxf6 40.exf6+ Kxf6 41.Rd2 Ne5+ 42.Kxf4 Ng6+ 43.Ke3 Ke5 44.Rf2 c5 45.g4 d4+ 46.Kd2 c4 47.g5 A disastrous error. White should have played 47.Rf5+, followed by Rb5, and it seems he could have drawn the game. The game was likely to proceed: 47.Rf5+ Ke4 48.Rb5 c3+ 49.Kd1 (or Kc1) 49...Kd3 50.Rxb4 Nf4 51.Rb3 Kc4 52.Rb8 followed eventually by Rc8. White certainly had no time for a slow move like g5. 47...c3+ 48.Kc2 Ke4 49.Re2+ Kd5 50.Re8 Ne5 51.Kb3 d3 52.Rd8+ Ke4 53.Rb8 d2 54.Kc2 Nc6|
|May-25-08|| ||littlefermat: 55.Re8+ Kf5 56.Rf8+ In this almost hopeless looking position White could have drawn the game with 56. g6. Black then answers ...Nd4+, for if ...Kxg6 then 57. Re6+ wins. The game then would have proceeded: 56.g6 Nd4+ 57.Kd1 Kxg6 58.Rd8 Nf5 59.Rxd2 Ne3+ 60.Kc1 cxd2+ 61.Kxd2 knight moves. White then plays Kd3, Kc4, Kb3 and he will be enabled to exchange the remaining pawn. A similar continuation results if Black in reply to 56. g6 plays ...Kf6. White then continues Rf8+, leading to the following play:; 56.g6 Kf6 57.Rf8+ Kxg6 58.Rf2 Nd4+ 59.Kd1 Nf5 60.Rxd2 Ne3+ 61.Kc1 cxd2+ 62.Kxd2 knight must move, and White again is enabled to force the exchange of pawns. 56...Kxg5 57.Rf2 Nd4+ 58.Kd1 Nf5 59.Rxd2 Ne3+ 60.Kc1 cxd2+ 61.Kxd2 Kf4 It is this move which gives Black a win. White cannot well play Kd3, for ...Kf3 would follow; if, then, Kd4 Black answers ...Ke2, and if Kc5, then ...Nc2, winning easily. Should White select Kd3, and, on Black's continuation ...Kf3, he answers Kd2, then Black wins with ...Ke4, followed by ...Kd4. It will be seen that the result of the game depended on Black's ...Kf4 move, which enabled him to hold the knight in the important position it occupied. Had White, on his fifty-sixth turn, moved g6, then Black's King would have been too far off and a drawn game would have resulted. 62.Kc1 Nc4 63.Kc2 Na5 64.Kd3 64. Kb2 was not any better, for, if he continues a3, Black answers ...b3. 64...Ke5 65.Ke3 Kd5 66.Kd3 Kc5 67.Kd2 Kd4 68.Kc2 Kc4 69.Kb2 Kd3 70.Kb1 Kc3 71.Kc1 Nc4 72.Kb1 Kd2 Causes White's surrender. If he plays Ka1, then Black answers ...Kc2, forcing a mate in four additional moves, and if a3, then ...bxa3 or ...b3, followed by ...Kc3, wins easily. 0-1|
|May-25-08|| ||Smothered Mate: This is Walter's show.|
|May-27-08|| ||Pawn and Two: <littlefermat> It is interesting to compare Fritz's analysis, with the Neil Brennen's analysis you have provided.|
Fritz agreed (.65) (18 ply) 10.Nc3 would have been White's strongest move. After (-.06) (18 ply) 10.Nf5 d5, the position was approximately equal.
At move 14, Fritz indicated White should have played: (.08) (22 ply) 14.Nd2 f6 15.Nf3. Fritz indicated 14.Be3 was slightly inferior: (-.27) (22 ply) 14.Be3 f6 15.f4.
Over the next several moves, Fritz indicated the advantage was shifting gradually to White.
As stated above, Black should have continued: (-.39) (20 ply) 14...f6 15.f4 fxe5 16.fxe5 Rxf1+ 17.Kxf1 Rf8+ 18.Kg1 Rf5 19.Bxa7 Rxe5.
Instead Black continued: (.03) (20 ply) 14...c5 15.Nd2.
The shift to White's favor continued at moves 15 & 16. At move 15, instead of (.07) (20 ply) 15...f6, Black played (.19) (20 ply) 15...a5, and at move 16, instead of (.14) (20 ply) 16...a4, Black played (.33) (20 ply) 16...f5.
At move 18, instead of (.34) (20 ply) 18...Rf8, Black played (.43) (20 ply) 18...Kf7.
White now has a definite edge, and at move 22 he should have continued: (.45) (20 ply) 22.b4 c6 23.bxc5 g6 24.c4 Nxc5 25.cxd5+ cxd5 26.Rab1 Rb8 27.Nd4+. At this point, White would have had a strong advantage: (.73) (20 ply) 27...Kd7 28.Nb5
Instead, White erred by playing: (.31) (20 ply) 22.h4 Nd8.
Pillsbury and Showalter then commented regarding 23.b4: <Probably premature; the preparatory move, 23.a3, was better; also, 23.h5 looks very strong.>
Fritz agrees with Pillsbury and Showalter: best was (.30) (21 ply) 23.a3 Ra8 24.b4 axb4 25.axb4 Rxa1 26.Rxa1 cxb4 27.cxb4 Kf7 28.Nd4 Ne6 29.Nxf5 Bxb4 30.Rd1; or (.24) (21 ply) 23.h5 Nc6 24.Rac1 Rb8 25.b4 axb4 26.Bxc5 Bxc5 27.cxb4 Rxb4 28.Rxc5, and White has a small advantage in either of these lines.
Instead, White played: (.13) (21 ply) 23.b4 axb4 24.cxb4.
At move 24, Black should have continued: (.16) (22 ply) 24...Rb8 25.a3 Rf8 26.Bxc5 Bxc5 27.bxc5 Nc6, with a position that is nearly equal.
Instead, Black played: (.71) (22 ply) 24...cxb4?. Fritz agreed the next moves were the best for both players: 25.Nd4+ Kd7 26.Nxf5 c6 27.Nxe7 Kxe7.
Fritz indicated that 27.Nxe7 Kxe7 was definitely a stronger line for White, than Brennen's recommendation of 27.Rac1.
If 27.Rac1, then: (.37) (21 ply) 27...Bf8 28.h5 Ra8, is a better line for Black than 27.Rac1 Nb7?.
After the game continuation, 27.Nxe7 Kxe7, White had a position that offered definite winning chances.
|May-28-08|| ||Pawn and Two: Fritz indicates 28.Bc5+? was a mistake, allowing the position to become approximately equal: 28...Ke6 29.Rab1 Kf5 30.Rxb4 Ne6 31.Bd6 Nxf4 32.g3 Ng6 33.Re1 Ke6: (.00) (20 ply) 34.a4; 34.Rb7; 34.h5; or 34.Kg2.|
Instead, White should have tried: (.65) (22 ply) 28.a3 bxa3 29.Rxa3 Ke6 30.h5 Rf8 31.g4 c5 32.Ra5 d4 33.f5+ Kd7. At this point Fritz indicates White has good winning chances with: (1.30) (21 ply) 34.Bf4 Kc6 35.e6 Nb7 36.Ra6+. White could also try 34.Ra6 Nc6 35.Bf4, with good winning chances.
In the 28.a3 line, Black had a better defensive try with: (.84) (21 ply) 32...Rf7 33.Kg2 Rfc7 34.Kg3 d4 35.f5+ Kf7; but after 36.Bf4! (1.20) (21 ply) 36...Rb7 37.Kf3, White again has good winning chances.
At move 30, the position was again approximately equal: (.01) (22 ply) 30.fxg5 hxg5 31.h5 Nf7 32.Kg3 Rh8 33.Rh1 Ra8 34.Bxb4 Nxe5 35.a3 Rh6 36.Rac1 Rb8 37.Rhe1 Kf5; or (.00) (22 ply) 30.hxg5 hxg5 31.Rh1 gxf4 32.Rh6+ Kxe5 33.Re1+ Kf5 34.Be7 Ra8 35.Rh5+ Kg6 36.Rg5+ Kf7.
|May-29-08|| ||Pawn and Two: As indicated in my last post, 32...Kxe5, would give Black an equal game. However, after Black played 32...Kf5, White could get a slight edge with: (.31 ) (22 ply) 33.Rf6+ Kxe5 34.Be7, but after either: (.19) (23 ply) 34...Rg3 35.Rf8 c5 36.Bxd8 Ke4 37.Re1+ Re3 38.Re8+ Kf5 39.R1xe3 fxe3+; or (.18) (23 ply) 34...c5 35.Re1+ Kd4 36.Rxf4+ Kc3 37.Bxc5 Nc6 38.Re3+, a draw should be the result.|
Instead of 33.Rf6+, White played 33.Re1, which slightly favored Black, but a draw was likely after: (-.33) (22ply) 33.Re1 Ra8 34.Re2 Re8 35.Bxb4 Ne6 36.Bd6 d4 37.g3 fxg3+ 38.Kxg3 Rg8+ 39.Kf2.
Black then returned the favor by playing 33...Rg6, which Fritz evaluated as equal: (.-.01) (23 ply) 34.Rxg6 Kxg6 35.e6 Nb7 36.Bxb4 c5 37.Bd2 Nd6 38.Re5 Ne4+ 39.Ke2 Nxd2 40.e7 Kf7 41.Kxd2.
In Neil Brennen's notes, he indicated 34.Rxg6, which is equal, was much superior to White's 34.Rh8. However, Fritz showed that 34.Rh8 is adequate for a draw: (-.15) (23 ply) 34.Rh8 Ne6 35.Rxc8 Nxc5 36.Rf8+ Ke6 37.Kf1 Ne4 38.Rb8 Kxe5 39.Rxb4 Rg8 40.Rb7 Ra8 41.Re7+ Kf6 42.R1xe4 dxe4 43.Rxe4 Rxa2, and the final position is a draw.
|May-30-08|| ||Pawn and Two: At move 34...Ra8, Pillsbury & Showalter commented, <34...Ne6 at once was far superior>.|
Fritz found that either move would result in an approximately equal position: (-.14) (20 ply) 34...Ne6 35.Rxc8 Nxc5 36.Rf8+ Ke6 37.Kf1 Ne4 38.Rb8 Kxe5 39.Rxb4 c5; or (.15) (20 ply) 34...Ra8 35.Kf1 Ne6 36.Rxa8 Nxc5 37.Rf8+ Kg5 38.Rb1 Ne6 39.Rf7 c5.
At move 35...Ne6, Pillsbury & Showalter commented: <The sacrifice of the exchange is, of course, forced, but gives Black a good game.> Brennen stated: <Brilliant and sound play, though it must be admitted that Black was forced to it. The sacrifice of the exchange leaves Black with strong pawns on the queenside, and it rests with White to fight for the draw.>
Fritz agreed that 35...Ne6 was Black's best move. An alternative to 35...Ne6 was 35...Ke6. However, after 35...Ke6 36.Bxb4 Kd7, White has an advantage: (.83) (24 ply) 37.Rh7+ Kc8 38.Bd6 Ne6 39.Rh8+ Kb7 40.Rb2+.
Brennen indicated that after 35...Ne6, it is White who must fight for the draw. Actually, the position finely balanced and dangerous for either player. Fritz rated the position as completely equal after: 35...Ne6 36.Rxa8 Nxc5 37.Rf8+ (.00) (23 ply) 37...Kg5 38.Rf7 Nd3+ 39.Kf3 Re6 40.Rg7+ Kf5 41.Rf7+ Kg5.
Instead of 37...Kg5, with equality, Black erred with: (.57) (23 ply) 37...Ke6? 38.Kf3 Nd3 39.Rf6+ Rxf6 40.exf6+ Kxf6 41.Rd2 Ne5+ 42.Kxf4 Ng6+.
None of the commentators pointed out Black's error 37...Ke6?.
Interestingly, the game continuation then followed the line indicated as best by Fritz, from move 38.Kf3 to 42...Ng6+.
After Black's error 37...Ke6?, deep analysis by Fritz indicated that it was White who had obtained some winning chances.
|May-31-08|| ||Pawn and Two: Fritz indicated both players made the best moves from move 38 through move 42.|
Fritz also confirmed that 43.Ke3 Ke5, was the best continuation.
At move 44, White erred by playing 44.Rf2?. Fritz indicated this move gave up most of White's advantage: (.20) (26 ply) 44.Rf2? d4+ 45.Kd3 Kd5 46.Kc2 c5.
At move 44, White should have played: (.63) (26 ply) 44.g3! c5 45.Rh2.
This position after 45.Rh2 is very difficult for Black. Fritz indicated all variations after 45.Rh2 lead to a loss for Black. The position is complicated, and perhaps a deeper and/or better search may find some saving line for Black.
Here are the main variations after 43.Ke3 Ke5 44.g3! c5 45.Rh2:
(2.05) (30 ply) 45...c4 46.Rh5+ Ke6 47.Kd4 Ne7 48.g4 Kf6 49.Rh1; (2.60) (24 ply) 49...Kg7 50.Re1 Kf7 51.Ke5 c3 52.Kd4 Kf6 53.Kc5, and White is winning.
(1.51) (30 ply) 45...d4+ 46.Kf3 Kd5 47.Rh5+ Kc4 48.Ke4 Ne7 49.Rh1 Nd5 50.g4 Nf6+; (2.36) (26 ply) 51.Kf3 Nd7 52.g5 Kd5 53.Rh6 Ne5+ 54.Kf4 c4 55.g6 Nxg6+ 56.Rxg6 c3 57.Rg8 d3 58.Ke3, and White is winning.
(1.10) (30 ply) 45...Nf8 46.Rh5+ Kd6 47.g4 Ke6 48.Rh8 Kf7 49.Rh6 Ng6 50.g5 Kg7 51.Rh1 Ne5 52.Kf4 Ng6+ 53.Kf5 c4; (2.51) (27 ply) 54.Rh6 Ne7+ 55.Ke5 c3 56.Rf6 c2 57.Rf1 Ng6+ 58.Kd4 Nf4 59.Ke3 Ne6 60.Kd3 Nxg5 61.Kxc2 Ne4 62.Rb1 Kf6 63.Rxb4, and White is winning.
(.95) (30 ply) 45...Ne7 46.Rh5+ Ke6 47.Rh7 Ng6 48.Rh6 Kf7 49.Rh5 Ne7 50.Rh7+ Ke6 51.g4 Kf6 52.Rh5 Kg6 53.Kf4 c4; (1.91) (27 ply) 54.Rh1 Kf6 55.g5+ Kg7 56.Ke5 c3; (2.85) (24 ply) 57.Kd4 Kg6 58.Rg1 Kf5 59.Re1 Ng6 60.Kxd5, and White is winning.
(.94) (30 ply) 45...Ke6 46.Rh6 Kf5 47.Rh5+ Ke6 48.g4 Nf8; (1.69) (29 ply) 49.Rg5 Nd7 50.Kf4 c4 51.Rg6+ Ke7 52.Kf5; (2.24) (25 ply) 52...Nf8 53.Rc6 Kd7 54.Rf6 c3 55.Rf7+ Ke8 56.Rc7 Kd8 57.Rc5 Nd7 58.Rc6 Nb8 59.Rd6+ Kc7 60.Rxd5, and White is winning.
Based on this analysis, I believe White missed a winning opportunity by not playing 44.g3!.
|Jun-01-08|| ||Pawn and Two: Regarding move 47.g5, Pillsbury and Showalter stated, <Ill-judged; 47.Rf5+ followed by Rb5 seems to draw.>|
Brennen claimed 47.g5 was a losing error: <A disastrous error. White should have played 47.Rf5+, followed by Rb5, and it seems he could have drawn the game. The game was likely to proceed: 47.Rf5+ Ke4 48.Rb5 c3+ 49.Kd1 (or Kc1) 49...Kd3 50.Rxb4 Nf4 51.Rb3 Kc4 52.Rb8 followed eventually by Rc8. White certainly had no time for a slow more like g5.>
The above evaluations are incorrect, and Brennen's variation also contains an error; 51...Kc4?. Correct is 51...Nh3, with an equal position.
In Brennen's variation, after 51...Kc4?, White can play 52.g5! with winning chances: (1.11) (25 ply) 52...d3 53.Rb8 Nd5 54.Re8 d2 55.Rd8 Ne3+ 56.Ke2 Ng2 57.Rd7 Kb4 58.Rd4+ Kc5 59.Re4.
In the game continuation, Fritz indicated 47.g5 or 47.Rf5+, and at least 7 other moves for White would lead to a totally equal position!
Fritz gave the following analysis: (.00) (31 ply) 47.g5 c3+ 48.Kd3 Kd5 49.Kc2 Ke4 50.Rf6 d3+ 51.Kb3 Nf4 52.g6 c2 53.Kb2 Ne2 54.Rc6, with an equal position.
Also, after: (.00) (31 ply) 47.Rf5+ Ke4 48.Rb5 c3+ 49.Kd1 Nf4 50.Rxb4 Nd5 51.Rb8 Ne3+ 52.Kc1 d3 53.Rd8 Nxg4 54.a4, the position is equal.
Fritz also evaluated the following lines as equal: (.00) (31 ply) 47.Rf3 c3+ 48.Kd1; or (.00) (31 ply) 47.Rf1 c3+ 48.Kc2; or (.00) (31 ply) 47.Re2+ Kf4 48.Re8; or (.00) (31 ply) 47.Kd1 Nf4 48.g5; or (.00) (31 ply) 47.Ke2 d3+ 48.Kd1; or (.00) (31 ply) 47.Kc1 c3 48.Kd1; or (.00) (31 ply) 47.Kc2 d3+ Kd1.
The losing error was not 47.g5. This interesting ending then continued with a few more surprising turns.
|Jun-02-08|| ||Pawn and Two: At move 51 the position was equal. At this point White had several moves that would have enabled him to draw.|
Perhaps the simplest continuation to draw was: 51.Rd8+ Ke4 52.Rd6 d3+ 53.Rxd3 Nxd3 54.g6 Ne1+ 55.Kc1.
Several other continuations also gave equality: 51.Kc1 d3 52.Kd1 c2+ 53.Kc1 Kd4 54.Rc8 Ke4 55.Rd8 Ke3 56.Rd6; or 51.Rb8 d3+ 52.Kd1 Kc4 53.Rf8 Kd4 54.Rf4+ Ke3 55.Rxb4; or 51.Kd1 d3 52.Rb8 Kc4 53.Rf8 Kd4 54.Rf4+ Ke3 55.Rxb4; or 51.Rc8 d3+ 52.Kd1 Ke6 53.Rd8 Kf5 54.Rd4 Kxg5 55.Rxb4; or 51.Rg8 d3+ 52.Kd1 Ke6 53.Rd8 Kf5 54.Rd4 Kxg5 55.Rxb4.
Instead, White made a serious error with 51.Kb3??. His position was then lost. Black can win by: 51...d3 52.Rb8 d2 53.Rd8+ Ke4 54.g6 Nxg6 55.Kc2 Nf4 56.Re8+ Kd4 57.Rd8+ Nd5 58.Kd1 Ke4 59.Ke2 Ne3.
Next it was Black's turn to make a serious error. After 53.Rb8, Black could have clinched the win with: 53...Nc6 54.Re8+ Kf5 55.Rf8+ Kxg5 56.Rg8+ Kf4 57.Rf8+ Ke3 58.Re8+ Kd2 59.Rh8 Na5+ 60.Kxb4 c2; or 53...Ke3 54.Re8 c2 55.Kb2 (if 55.Rxe5+ Kd2) Kd2 56.Rc8 Nd7 57.Rc6 Nb6 58.g6 Na4+ 59.Kb3 Nc3 60.Rxc3 bxc3.
Instead, Black played 53...d2??, and the position was again equal!!
|Jun-05-08|| ||Pawn and Two: At move 56, White made a fatal error, 56.Rf8+?. He should have played, with an equal game, 56.g6 Nd4+ 57.Kd1 Kxg6 58.Rd8 Nf5 59.Rd3 (59.Rxd2 Ne3+ 60.Ke2 cxd2 61.Kxd2 Nd5 62.Kd3 Kf6 63.Kc4 Ke6 64.a3 also draws) Kg5 60.a3 bxa3 61.Rxa3 a2 62.Ra3 Ne3+ 63.Kxd2 Nc4+ 64.Kc2 Nxa3+ 65.Kb2 Kf4 66.Kxa2.|
Fritz indicated 56.Re3 Ne5 57.Rg3 Kg6 58.Kd1 Nc4 59.Kc2 Nb2 60.Rg1, would also draw.
Brennen indicated a draw would result after: 56.g6 Kf6 57.Rf8+. However, Black would have had some anxious moments, as White could improve with: 57.Re4! Kg7 58.Rc4 Ne7 59.Rc7 Kf6 60.g7 Nf5 61.g8Q ne3+ 62.Kd3 d1Q+ 63.Kxe3 Qe1+ 64.Kd3 Qf1+ 65.Kc2 b3+ 66.axb3 Qe2+ 67.Kxc3, and the Nalimov tables show the final position is a draw.
A well contested game with a highly interesting ending.

|Mar-22-11|| ||crawfb5: <"White adopted the Ruy Lopez opening and after two minor pieces and queens were exchanged, the game developed into a very complicated ending, in which White eventually won the exchange, but at the cost of allowing Black two strong passed pawns on the queen's wing against one on White's king's side. White, instead of playing for the draw, misjudged the situation and got into difficulties, finally being obliged to resign after 72 moves.">|

Of course ... NxR and White queens. But there are other black moves to consider.|
