 | | Richard Taylor: I disagree that the whole combo had to be seen as f4 is not hard to see and White has a stonger game after 19 Q:f5
-which is fairly easy to see - and even if 19. ...N:e5 20. f:e5 Whiteis fairly clearly winning. He is going to get three pieces for a queen with a very strong position I saw the main - or the initial few moves of the main line and concluded that that was it and I saw some of the ideas - driving the pawn to e6 a possible move of the rook to the h file comnbinations on the a1 to h8 diagonal etc -in an OTB game I would have worked hard and calculate most of it. But of course it is not easy to calculate these variatons in total - one works out main lines and a few sub lines: and then judges the position as winning...or not..humans judge and calculate - computers 'stupidly' calculate everything and they judge - but a human can judge by also experience and by "sight". |

| | Richard Taylor: But I agree with <Gipsy> it is inspired chess - regardless - and it always takes courage and vision to give away one's queen... |

 | | patzer2: The Sunday puzzle solution 19. Qxe5! at first appears to be a true Queen sacrifice, as opposed to a sham sacrifice leading to an easily calculated win. However, when you consider that White loses quickly in other lines, the "sacrfice" of the Queen for three pieces is practically forced. For example after the main alternative 19. Nxf6+? Bxf6
20. Qg4 Nc5 21. Rad1 d3 22. Bxf6 Qxf6 23. Re5 Qd6 24. Qf3 Rad8  , white is two pawns down in an obvioulsy lost position. Black could have put up more resistance with 21...d3, but after <koster>'s idea of 22. Bd2! White seems to control the position for a decisive win. An analysis with Fritz 8 follows: 21... d3!? 22. Bd2! (Perhaps not so effective here is 22. Re4!? Qb6+ 23. Kf1 Rad8 24. Rd1 h5 25. Bh6 Qb5 26. Rd2 Qc5 27. g4 Qc1+ 28. Re1 Qc5 29. gxh5 gxh5 30. Rg2 Rg8 31. Nxg8 Rxg8 32. Rxg8+ Kxg8 33. Re4 Kh7 34. Be3 Qe7 35. Bc4 f5 36. Rd4 c5 37. Rxd3 Qxe5 38. b3 b6 39. a3 h4 40. Bd2 Kg6  with some practical survival chances for Black.) 22... Qd4+ 23. Kh1 Qxb2 24. Ne4 Qa3 25. Bc3 d2 26. Bxd2 Rae8 27. Nd6 Kg8 28. Bh6 Re7 29. Re2 a5 30. Rf1 a4 31. Bxf8 Kxf8 32. Bxf7 Kg7 33. Ne8+ Kh8 34. e6 Qd3 35. Ree1 Qc2 36. Nf6 Qxa2 37. Ng8  and White wins (
+6.75 @ 14 depth & 1260kN/s).

| | patzer2: Although it's not clear whether it's a forced winning combination, the clearance move 15. e5! is an outstanding positional sacrifice. Certainly it played a key role in setting up the winning 19. Qxe5! sacrfice. |
|
| Jan-22-09 | | Extremophile: 19.Qxe5 is not a sacrifice! White wins material by 19.Qxe5. |
|
| Jan-22-09 | | andymac: "Victor: Laszlo" would have been slightly better, I think, but still an excellent pun. Also a great movie, of course. |

| Jan-22-09 | | blue wave: 18.f4! a killer move!! |

 | | kevin86: A queen is a strong piece,but white will have a mere two bishops and rook for her-a winning margin... |
|
| Jan-22-09 | | xrt999: CG has 19.Qhx5 listed as a sac, but technically the queen is being attacked, and has no square to move to, so I really dont think this fits the definition of a sacrifice. Now, if the queen had a square to move to safety and instead opted for this line, then yes, I would call it a sacrifice. In other words, the true sac is 18.f4, it locks the queen into black's position with no safety squre. So, the notation above should say "Q sac: 18.f4". Just my opinion. |
|
| Jan-22-09 | | xrt999: I mean 19.Qxe5 of course.
I like this game because it shows that chess is not always so clear when it comes to material. You have to consider many other facets such as the quality of pieces, the degree of attack and defense, and position. (or time and space, in addition to material). In all cases white is ahead, but is down a full piece. (Q-P-P to B-B-N) Even if one was advanced enough to be able to calculate such a position from move 18 through 21, and see the board as it is at move 21, you still would need to be able to evaluate the nuances that I referenced above, and be convinced enough to go forward with a move like 18.f4. This is the sign of a great GM level player. Thanks CG for showcasing this game. |

|
| Jan-22-09 | | njchess: Nice game. White's attack is crushingly accurate.
< Andrijadj: Music Box,right?The movie...> Victor Laszlo is a reference to a character portrayed by Paul Henreid from the classic film Casablanca (1942) starring Humphrey Bogart, Ingrid Bergman, and Claude Rains. Nice pun. |

 | | Once: Stunning game, and a good Casablanca pun to boot. Thanks, CG, for making this a very worthy GOTD. The only downside is the realisation that no matter how much I practice I can never imagine myself finding white's 19th. I can well believe that this is one of the toughest Sundays ever. |
|
| Jan-22-09 | | WhiteRook48: amazing choice for GOTD, but I usually can't get puns and not on this one either. I'm a total patzer. Well, most of the time. |
|
| Jan-24-09 | | Andrijadj: Thanks Njchess...Main antagonist of the famous film Music Box is also called laszlo,but Mischa,not Victor...I made a mistake... |
|
| Apr-12-09 | | WhiteRook48: 26 Ne8+ now Black is the one sacrificing |

 | | An Englishman: Good Evening: Already knew the game, but this remains an interesting puzzle, more a test of one's judgment than one's calculating ability. Can you judge whether or not the three minor pieces are worth more than the Queen and 2 pawns? |
|
| Apr-06-19 | | Walter Glattke: If 23.-d3, one could also play 24.e7 Qxf5 25.exf8Q+ Rxf8 26.Rf1 all ways good for White. |
|
| Apr-06-19 | | Boerboel Guy: Not "Very Difficult". I found the move very obvious and the game flows easily thanks to the active minor pieces. |
|
| Apr-06-19 | | mel gibson: That is difficult.
I thought that I'd just swap Knights to get the Queen out of trap.
I didn't see that a Queen sac was the way to go.Stockfish 10 says:

 | | agb2002: White has the bishop pair for a bishop, a knight and a pawn. Black threatens gxf5.
The obvious 19.Nxf6+ Bxf6 20.Qg4 ends up two pawns down, probably without enough compensation. A promising alternative is 19.Qxe5 Nxe5 20.Nxf6+: A) 20... Kh8 21.fxe5 with several threats: Nxh7, Bh6, Re4. B) 20... Kg7 21.fxe5 (21.Nh5+ gxh5 22.Bxd8 Nd3 is probably unnecessarily complicated) looks similar to A. C) 20... Qxf6 21.Bxf6 Nd3 22.Red1 Nxf4 23.Rxd4 + - [2B vs n+p]. |
|
| Apr-06-19 | | malt: Looked at 19.N:f6+ B:f6 20.B:f6 N:f6 21.Qd3 did not think this was the answer 17.Nc5 looks good. |
|
| Apr-06-19 | | saturn2: With 19. Qxe5 Nxe5 20. fxe5
I deviated in the second move but thought white would also get 3 pieces for the queen. 20...Qb6 21. Bxf6
If black gives back to queen he is a piece down. 20...Nxe4 21. Bxd8 Raxd8 22. Rxe4
The other question is if 3 light pieces is enough for Q+2P |
