| mdz: I did, though I did not see the mate in "critical line" 49...Kh8 50.Nf7+ Kh7 51.Rg7x on move 42. But intuition said that after 47.N:h7+ white is winning. Humans, unlike computers don't have to calculate till mate :) |

| An Englishman: Good Evening: I wonder if Fischer knew about this game before he used the same variation versus Panno. |
|
| Mar-20-05 |
| pastpawn: I wonder if Panno found the combination over the board, or if he found it analyzing after an adjournment soon after move 40. |
|
| Mar-20-05 |
| Hinchliffe: <An Englishman> Most definitely. |

| patzer2: Panno's 43. Rxd5!! initiates a brilliant series of deflections, giving Black the unpleaseant choice between entering a mating net or allowing a decisive passed pawn. After <43.Rxd5!! exd5 44.e6 fxe6> [44...Qf8 45.Qxf7+ Qxf7 46.exf7+ Kh8 47.Re8+ Nf8 48.Rxf8#] <45.Rxe6 Qf8> [45...Qd8 46.Qf7+ Kh8 47.Qxh7#] <46.Qxf8+ Kxf8> [46...Nxf8 47.Nf6+ Kh8 48.Nf7#] <47.Nxh7+ Kg8 48.Ng5! Bb7 49.Rxg6+ Kf8> [49...Kh8 50.Nf7+ Kh7 51.Rg7#] <50.h7> 1–0, Black resigns as 50...Ke7 Re6+  is clearly decisive. |

| minimaxing: I had this up to 48. Ng5, when I moronically deviated with Nf6+ (still winning, but a much harder game). It took around half an hour to solve this all the way through, which is longer than most of the games I play. |

| ongyj: I've nothing else to say. Absolute brilliance on White play. |
|

| pawntificator: Very nice. I wish I could say I got this one. I considered the winning move, along with every other possible sacrifice, and I wasn't getting anywhere. My excuse is that it is 2am here. I lobby that chessgames.com release the puzzle of the day based on my time zone. Yep. |

| catfriend: Solved a Sunday:) That's just the only threat possible to do... |
|
| Mar-20-05 |
| Dick Brain: <catfriend> had you considered the defence 45 ...Qf8 as played in your analysis? |
|
Mar-20-05
|
| patzer2: A simple but instructive mate is available to White if Black plays 44... de5:44...de5 45.exf7+  h8
[45...Nxf7 46.Rxe7 Be6 47.Qxf7+ Bxf7 48.Nf6+ Kf8 (48...Kh8 49.Nxf7#) 49.Rxf7#; 45...Qxf7 46.Qxf7+ Nxf7 47.Re8#
45...Kf8 Nxh7#]
46.f8 + xf8 47.xf8# |
|
Mar-20-05
|
| patzer2: Also instructive is the possibility 44...f5 45.exd7! Qxd7 46.Nf6+ , winning the Queen by combining the discovered attack and Knight Fork tactics. |

| Mar-20-05 |
| Dick Brain: I had an interesting thought about this game in relation to Fischer vs Panno, 1970
in the Elisakses game, maybe Black could have prevented the 43. Rxd5 breakthrough with 42...Qf8 since he plays it later. It surely looks like it would at least gain time. if that be that case, maybe White should have played 42. Be4! after which 42...Qf8 is not suffient because 43. Bxd5 exd5 44. Rxd5 creates too many threats. Also capuring the bishop 42... dxe4 is not good because 43. Rxd7! Bxd7 44. Nf6+ Kh8 45. Nxd7: too many threats. 42. Be4! would have been like Fischer's 28. Be4! that he played in 1970 against Panno although with a different target in mind. |

| inhalaattori: Interestingly I figured out the move intuitively, but when I did some analysis on the position with Crafty, it suggested: depth=12 15/42 +0.66 43. Rc1 a5 44. Bb5 Rc5 45. Re1 Ra7 46. Re3 d4 47. Re4 Rc7 48. Bc4 Nb6 Nodes: 80728534 NPS: 287904
It's really weird a computer can overlook 43. Rxd5! |

|
| patzer2: If Black plays 44...e6, an interesting pursuit mate could ensue: 44...f6 45.exd7! fxg5 46.Rxe7! (a good alternative is 46.Nf6+! Kf7 47.Rxe7+ Kxe7 48.Nxd5+ Kxd7 49.Bh3+ g4 50.Bxg4+ ) 46...gxf4 47.Rg7+! (A simpler win is 47.Re8+! Kf7 48.Rxc8 ) 47...Kf8 48.Nf6 Bxd7 49.Nxh7+ Ke8 50.Nf6+ Kf8 51.Nxd7+ Ke8 52.h7 Ne7 53.Nb6 Kd8 54.h8Q+ Kc7 55.Rxe7+ Kxb6 56.Qd4+ Kc6 57.Qf6+ Kc5 58.Rc7# |
|
| Mar-20-05 |
| catfriend: <Dick brain> Yep, since it's the only place where black can move his queen without getting a mate in few moves. But I must say I stopped counting after 47.Nxh7+ since I was 100% sure it's won for white. |

| bishopmate: Second time i found a Sunday puzzle---I didn't find the whole continuation but i knew the rook sac was the right move after i saw the knight check on h7 to get a passed pawn |

| patzer2: <Dick Brain> I like your proposed 42. Be4!, even if I'm not sure if it is better than the move played in the game. Still it's a strong but subtle move that is likely to be initially overlooked by both computer programs as well as strong human players. Fritz 8 @ 16 depth assesses a win for White after 42. Be4! dxe4 with 43. Red1! (instead of 43. Rxd7): Oscar Panno - Erich Gottlieb Eliskases

| patzer2: <Dick Brain> Looks like Fritz initially underestimated the strength of your 42. Be4! dxe4 43. Rxd7+! After 42. Be4 dxe4 <43.Rxd7!> Bxd7 (43...Qxd7 44.Qf6 Kf8 45.Nxh7+ Ke8 46.Qh8+ Ke7 47.Qf8#) 44.Nf6+ Kh8 45.Nxd7 f5 46.Nxb8 Nxb8 47.Rd1 Kg8 48.Qd2 Rc8 49.Qd6 Qxd6 50.Rxd6 Nc6 51.Rxe6 a5 52.Kg2 Kh8 53.g4 Kg8 54.gxf5 gxf5 55.Kg3 Nd4 56.Re7 , it's a crushing win for White (+ 6.22 @ 16 depth per Fritz 8). |

| kevin86: White denuded black's kingside like a swarm of locusts! Note the horrible isolation of black's pieces:every one but the king-is on the queenside--with the empty king file acting as an ironic wall of China separating the king from his army. |

| patzer2: <kevin 86> I really enjoy the metaphors and similes you use in susccintly summarizing the strategy and tactics involved in a decisive chess game. |
