| Jan-11-11 | | theodor: it's rather cruel for a christian! |
|
| Feb-10-20 | | lost in space: 37...Rd8!! wins on the spot.
37...Qa4 wins too, but slow. |
|
| Feb-10-20 | | agb2002: Black has two extra pawns.
White threatens Qxe4.
The black queen pins her colleague, allowing the skewer 37... Rd8 (38.Qxe4 Rxd1#). |
|
| Feb-10-20 | | stacase: Took about a second to notice that Black's Pawn on b3 provides coverage for a back rank mate, and if only White's Rook could get there. Another second to notice that among other things, White's Queen is pinned. And just how fast can I pick up my Rook and bang it down on d8? [evil laugh] Ha ha ha ha! [/evil laugh] |

 | | gawain: I see I solved this one in 2009. Wow, that long ago? Well, it is still a good Monday puzzle |
|
| Feb-10-20 | | zb2cr: 37. ... Rd8, applying a "cross-pin"--the White Queen is pinned in two directions at once. If White plays 38. Qxe4, Rxd1#.
If White plays something like 38. Rc1, Rxd3 wins the Queen for nothing. |

 | | jffun1958: Can it be such simple? I hesitated for a while but
37...Rd8
is winning immediately. |

| Feb-10-20 | | saturn2: 37...Rd8 wind the queen |

 | | FSR: You don't see the Katalimov Variation (2...b6) every day. To my surprise, Opening Explorer shows it scoring very well for Black, albeit with a small sample size. Opening Explorer shows that it is played only about a seventh as often as Black's sixth most common move, 2...Nf6. ChessBase Online's much larger database shows White scoring 53.2% in 1809 games against the Katalimov, a bit better than against most second moves. |

| Feb-10-20 | | Walter Glattke: 37.-Rd8 38.Kc1 Rxd3 or less good 37.-Qa4 38.Kc1 Rc8+ 39.Kd2 Rc2+ 40.Ke3 Qxe5+ |
|
| Feb-10-20 | | malt: 37...Rd8 Wins |

 | | ferrabraz: 14. Nb6 looks good: attacks the Na5, the Ra8 and the Qc8. If 14...Qc5, then 15.Be3. Is the score ok? |
|
| Feb-10-20 | | saturn2: <ferrabraz: 14. Nb6 looks good>
Black was hoping for that and let 14...Nb3+ follow |

| Feb-10-20 | | Vermit: A tactical trick I learnt many years ago from Yanofsky-Aitken, Hastings 1946/47: Yanofsky vs Aitken, 1947 |
|
| Feb-10-20 | | Damenlaeuferbauer: After long pondering, my old French friend Christian, who has been three times champion of his country, finally found 37.-,Rd8!, winning the game on the spot. By the way, a former girl friend of mine played the Katalimov variation of the Sicilian defense (1.e4,c5 2.Nf3,b6!? 3.d4,cxd4 4.Nxd4,Bb7) regularly in the early 80s with not worse results than in the main lines (Najdorf, Dragon, and Scheveningen at that time). |

| Feb-10-20 | | Cheapo by the Dozen: Great Monday puzzle: Solvable in a few seconds, yet suprising even so. |
|
| Feb-10-20 | | thegoodanarchist: This is a nice back rank mate |
|
| Feb-10-20 | | Ratt Boy: <Vermit: A tactical trick I learnt many years ago from Yanofsky-Aitken, Hastings 1946/47:

Thanks for linking to that game.
I learned that trick in a team tourney. I was up the Exchange, butt my opponent played that tactical trick, winning my R and the game.
My opponent told me he'd played the same trick a week prior. |

| Feb-10-20 | | DrGridlock: Took me a little too long to solve (though I eventually did). My thinking was - Black's queen is attacked, and "en pris" - so I either need to move the queen or give a check. I kept trying to find a way to move the queen to the a-file and dance around White's b-pawn to deliver a mate. Dancing around the b-pawn finally lit the light bulb - "hey, white's king is kind of trapped on the back rank, so any check is quite lethal." I found the x-ran by lining up the black rook on the e-file, compounded by the fact that white's queen is pinned so that it cannot move off of the b2-h7 diagonal. All features kind of mesh together neatly when you finally find them. |

| Feb-10-20 | | TheaN: Pretty sure I did see this before and I have, considering I posted in 2009. This still came roughly as fast as it did then, but for different reasons. Point is, no other move for Black really makes sense. I guess the only other sensible move for a Monday would be 37....Qa4, and surprise, that's actually dead won also after 38.Kc1 (any other move allows the rook to join with tempo after Qa2+ with Rc8+) Qa1+ 39.Kd2 Qxb2+ 40.Ke1 Qxe5+ -+ and White is four pawns down. However, if you find a good move, look for a better one. |

| Feb-10-20 | | landshark: Black was clearly won already but what a nice finish! |
|

 | | dorsnikov: I went with 38... Q-a4. Not the killer move but plausible. I think ??? |
|
Feb-10-20
 | | Breunor: I also went for Qa4. Glad to see it evaluates as -8.64 for black but the actual move is better. |
|
| Feb-11-20 | | Nullifidian: The white queen is pinned, so 37... ♖d8 wins. If 38. ♕xe4, then ♖xd4# |
