 | | paulalbert: <ficsplayer54> I think instead of 33...Rxe8 33... Qxe8 preserves the mate threat Qh5 if white plays 34 Rxg1 so white never gains the material suggested in your line, unless I'm missing something. |

| Dec-16-12 | | agb2002: Black has a bishop and a knight for the bishop pair and a pawn. White might consider Be3 and Qa4 forcing the exchange of queens (... Qxc3 Qxa7+ Kc8 Rc1, etc.). The obvious move is 25... Nxg3:
A) 26.hxg3 Rxg3+
A.1) 27.Kh2 Qg6 28.Bxd3 Rg8 29.Kh1 (29.Qb5 Rh3+ 30.Kxh3 Qg3#) 29... Rh3+ 30.Rh2 Qg2#. A.2) 27.Kh1 Qg6 29.Bxd3 Rg8 is similar to A.1.
A.3) 27.Kf2 Rdg8
A.3.a) 28.Bxd3 Nxd3+ wins the queen.
A.3.b) 28.Ke1 Bxe2 29.Kxe2 (29.N(R)xe2 Nd3+ and 30... Nxb4) 29... Rg2+ A.3.b.i) 30.Rf2 Rxf2 31.Kxf2 Nd3+, etc.
A.3.b.ii) 30.Ke3 Nc4+ 31.Kd3(4) (31.Kf4 Qh6+ 32.Kf5 Qg6+ 33.Kf4 Qg5#) 31... Rd8+ 32.Nd5 Rxa2 - +. A.3.b.iii) 30.Kd1 Rxa2 31.Nxa2 Rd8+ 32.Bd2 (32.Ke2 Qc2+) 32... Nc4 33.Rf2 Ne3+ 34.Ke2 Nc2, unclear. For example, 35.Qc3 Qb5+ 36.Kd1 Qb1+ 37.Ke2 Qxa2. B) 26.Kf2 Nxf1 - +.
C) 26.Bxd3 Nxf1+ 27.Kxf1 Nxd3 - +. |
|
| Dec-16-12 | | agb2002: 27... Rdg8, after 27.Kf2, loses miserably to 28.Bf4. However, 27... Bxe2 28.Bf4 Rxf3+ 29.Kxe2 Rxf4 30.Rxf4 Nd3 wins. Very instructive. |

 | | Jimfromprovidence: <Morf> After 27 Kf2 Rxf3 28 Bxf3 Bxf1, white has the p(w)inning move 29 Bf4, which puts 2 pieces en prise.
click for larger viewBlack will lose one of the two pieces.
<AI> After 27 Kf2 Rxf3 28 Bxf3 Qf6, white has the saving move 29 Ne2.
click for larger viewHe can afford 29….Qxf3+ because he will remain a piece ahead after 30 Ke1. The trickiest part of this line is after 29…Qh4+ where white only has 30 Kg1, exposing himself to the same threats as in the text.
click for larger viewIt looks like the bishop and knight will serve as adequate shields, starting with 30…Rg8+ 31 Ng3. Check out the line that, I, <rilkefan> and <agb2002> put out there. It ends with white sacrificing a rook, just to get it back one move later with a knight fork of rook and queen, where the queen is helpless to defend the rook. |
|
| Dec-16-12 | | Patriot: <agb2002> You missed a candidate (28.Bf4)--that happens sometimes. I found 27...Bxe2 but also missed 28.Bf4 in that line. The follow-up you mentioned is nice. I missed a few other things as well:
27.Kf2 Bxe2 28.Kxg3 Bxf1? 29.Bf4 draws
27.Kf2 Bxe2 28.Kxe2 Rg2+ 29.Rf2 and the straight-forward 29...Rxf2+ wins because of 30.Kxf2 Nd3+. My line (c) was a result of a visualization error. I was seeing the rook on g3--not g2, which is why I decided 30.Qc7+ and not 30.Qf6#. |
|
| Dec-16-12 | | Patriot: <Jimfromprovidence> That's some tricky stuff! 29.Ne2 would be very hard to find. All it takes is missing one defensive resource somewhere and the evaluation changes dramatically from what we expected. |
|
| Dec-16-12 | | ficsplayer54: Thanks paul albert and dpcptacg, and anyone else I may have missed :). |
|
| Dec-16-12 | | rilkefan: Ah, this was correspondence. |
|
| Dec-16-12 | | morfishine: <Jimfromprovidence> Thanks for jumping in here. All in all, perhaps <27.Kf2> is shaping up to be a 'spoiler' instead of the losing 27.Kh2 for White I feel much better about this problem, thanks to you and <Abdel Irada>; in that my overall assessment of the position was on the right track; Sometimes it feels better to play the better continuation than what was played, even if I couldn't finish off the sequence |
|
| Dec-16-12 | | numbersguy70: Not a spoiler. 27. Kf2 loses to Bxe2, leaving d3 unprotected and the black king will be easily forced back to either f2, f4, or e1 where Nd3 will win the queen. |
|
| Dec-16-12 | | Kikoman: Wow! I got it! <Nxg3!> and that's it. Kihx3 |
|
| Dec-16-12 | | Shamot: Looking at how black finished the game, I do not understand the need for 32...f5. Why not 32...Qg7# ? |
|
| Dec-16-12 | | Shamot: Oops!!! my bad! I see the rook on a2 now. |

| Dec-17-12 | | Abdel Irada: <<•>"Will the real Prince of Wallachia please stand up?" or "A Blood Feast"<•>> <<~>Part 2 of 3. Part 1 was posted yesterday.<~>> <(1.2) 29. Ke1, Qh4†> Now White must select one of
<(1.2.1) 30. Kaf2, Nxf3†
31. Kd1, Bxf1†
32. Nd5...>
(a) 32. Rd2, Qe1†; 33. Kc2, Rxd2† . (b) 32. Bd2, Qxf2 . (c) 32. Kc2, Qxf2† . <32. ...Qxf2
33. Bf4†, Ka8 >, or
<(1.2.2) 30. Rff2?, Nxf3†
31. Kd1, Qh1†
32. Rf1, Qxf1#> or
<(1.2.3) 30. Kd2, Bxf1†
31. Kc2...>
Or 31. Nd5, Qf2†; 32. Kc3, Rc8†; 33. Kb3, Qxf3† and (a) 34. Kb2?, Nd3† ; (b) 34. Ka4?, b5† ; (c) 34. Be3, Qd1†; 35. Kb2, Nd3#; (d) 34. Ne3, Bc4† or (e) 34. Nc3, Bc4† . <31. ... Qf2†
32. Kb1...>
No better is 32. Be2, Bxe2 and either (a) 33. Nxe2, Qxe2†; 34. Kb1, Qd3† , or (b) 33. Kb3, Nd3 and (b.1) 34. Rxe2, Nxc1†; 35. Ka4, Nxe2 , (b.2) 34. Nxe2, Nxb4 , (b.3) 34. Nd5, Nxb4 or (b.4) 34. Qe7, Nxc1† . <32. ... Qxf3 >
As in note (a) above, Black's material advantage is not large, but in conjunction with positional pressure, the incoordination of White's pieces and the passed black h-pawn, the practical advantage is crushing. One more retreat square to consider in this line:
<(1.2.4) 30. Kd1, Bxf1†> White has four ways to get out of check.
<(1.2.4.1) 31. Nd5, Nxf3 > Again, a slight material edge conjoined to a strong position adds up to a win for Black. <(1.2.4.2) 31. Bd2, Nxf3 > Here Black's advantage is even clearer.
<(1.2.4.3) 31. Rd2, Nxf3 > This was a dangerous bid for advantage on White's part, but Black's queen is well placed. <(1.2.4.4) 31. Kc2, Qf2† > This wins for Black as in line (1.2.3) above. This takes us back to move 29, where two ideas remain for White to explore. Moving the king fails, so let's consider saving the rook on f1, either by moving it or blocking the bishop's access to it. <(1.3) 29. Rg1, Qxf3†
30. Ke1, Bc2! >
If there's an adequate defense against 31. ...Nd3†, it is far from apparent. Meanwhile, other rook moves look worse: (a) 29. Re1?, Qxf3†; 30. Kg1, Rg8†; 31. Kh2, Qh5#, or (b) 29. Rd1, Qxf3†; 30. Ke1, Qf1†; 31. Kd2, Nc4†; 32. Qxc4, Bxc4† , or (c) 29. Rh1, Qxf3†; 30. Ke1, Qxh1† . <<~>End part 2 of 3. Part 3 appears below.<~>> |
|
| Dec-17-12 | | Abdel Irada: <<•>"Will the real Prince of Wallachia please stand up?" or "A Blood Feast"<•>> <<~>Part 3 of 3. Part 2 appears above.<~>> Final idea:
<(1.4) 29. Ne2, Bxe2
30. Kxe2...>
Of course not 30. Rxe2?, Nd3†, winning the queen.
<30. ...Qa6†
31. Ke3...>
Other moves lose to the ...Nd3† fork.
<31. ...Qxf1 >
Paradoxical. Black is still a piece down and White is not in check, but no means is apparent of stopping the dual threats 32. ...Qxc1† and 32. ...Qxf3#. If the lines with 27. Kf2 are to be saved, there's one other move, using the same theme, that must be examined. <(1.5) 29. Re2, Qxf3†
30. Ke1, Qg3† >
No defense seems to hold: (a) 31. Rff2?, Nf3†; 32. Kd1 (32. Kf1??, Qg1#), Qg1†; 33. Rf1, Qxf1†; 34. Re1, Qxe1#, or (b) 31. Ref2, Nf3†; 32. Kd1, Bxf1† and Black wins as in variation (1.2.3). We have now ruled out 27. Kf2. This is not good news for White, who must now try running to his exposed kingside, where two square are available. <(2) 27. Kh1, Qf6>
Also strong is 27. ...Rdg8, but I prefer to pre-empt 28. Bf4. <28. Bxd3...>
Inadvisable is 28. Rf2?, Qh4†; 29. Rh2, Rg1†!; 30. Kxg1, Qe1†; 31. Kg2 (31. Bf1?, Qxf1#), Rg8†; 32. Kh3, Qg3#. <28. ...Rdg8!>
This introduces two new mate threats, depending on how White defends. <(2.1) 29. Nd5 (or other neutral move), Rh3†
30. Rh2, Rxh2†
31. Kxh2, Qh4#>
<(2.2) 29. Rh2, Qxf3†!
30. Rxf3, Rg1#>
The only way I see for White to delay mate is with a series of horizon-effect moves: <(2.3) 29. Bf4, Qxf4
30. Qd6†, Ka8
31. Qf8†, Rxf8 >
To be sure, White isn't mated yet, but the game is no less over. There is now one final alternative to consider.
<(3) 27. Kh2, Rdg8>
White seems to have two choices:
<(3.1) 28. Bxd3, Qf6 > Also good is 28. ...Nxd3; 29. Qb1, Nxc1; 30. Qxc1, Qf6 . But this is quicker, since 29. Kh1 is mate in three as in (2.1), and the only way to prevent mate is to give up the queen. <(3.2) 28. Bf4, Rg2†
29. Kh1, Qg6!
30. Bxe5†, Ka8 >
We may now regard it as conclusive: Rizzuti, not Wallach, is the Prince of Wallachia, and Wallach, not Rizzuti, will end this battle as a wan and pallid victim of chessic vampirism. |
|
| Dec-17-12 | | Abdel Irada: <Jimfromprovidence>: I hadn't posted it until now, but I did look at 29. Ne2 in my variation (1.4). Please let me know if you find any better defenses for White after 29. ...Bxe2; 30. Kxe2, Qa6†. Note that by removing the knight from c3, White removed his defense against checks on the f1-a6 diagonal, and here that seems to be significant. |
|
| Dec-17-12 | | Abdel Irada: Apparently Wallach found a defense in the 27. Kh2 line that I had underestimated: 28. Qe7. However, since it leads to play not much different than that in my (3.2), the results are unsurprising. I am rather surprised, however, that he ran to h2 when it appears that going to f2 offers far stiffer resistance. |

 | | doubledrooks: <Abdel Irada>: In your line 1.4, instead of 30 Kxe2, how about 30. Bf4, and now: a. 30...Bxf3 31. Bxe5+ Qxe5 32. Kxf3
b. 30...Bxf1 31. Bxe5+ Qxe5 32. Kxf1 Qg3 33. Rf2
c. 30...Qxf4 31. Kxe2 Nd3 32. Qb1 Qh2+ 33. Ke3 Qh6+ 34. Ke2 Qa6 35. Ke3 Regardless of whether or not 30. Bf4 holds for White I commend you for your work in solving this problem. |
|
| Dec-17-12 | | Abdel Irada: <Jimfromprovidence>, <doubledrooks>: Now 30. Bf4! is quite a resource — very unintuitive, and not something that had occurred to me. Congratulations. I'm going to have to take some more time looking at that line. So far, I suspect it might end in a draw if Black follows your line c, but varies with 34. ...Nf4†. Most vexatious. |
