| Jan-14-20 | | SamAtoms1980: If it were me I would have set the puzzle one move back. 38....Qg2+ 39.Qxg2 f2 BTW, how is the "quick" time control different from ordinary rapid? |

| | Phony Benoni: Back in my day, "Quick" meant 10-munites for the entire game. Don't know if that's changed in the last twenty years. |

| Jan-14-20 | | dashjon: The pawn is mightier than the sword! |
|
| Jan-14-20 | | agb2002: Black is a queen down.
White threatens Qh3+ and Bxg8.
The bishop x-rays the white king and the rook on e1 is defenseless. Therefore, 39... f2: A) 40.Rf1 Bxg2#.
B) 40.Qxe4 fxe1=Q(R)#.
C) 40.Rg1 Rxg2 and mate next.
D) 40.h3(4) fxe1=Q+ and mate follows.
E) 40.Bxg8 Bxg2#.
F) 40.Rxe4 fxe1=Q(R)+ and mate next. |
|
| Jan-14-20 | | Cheapo by the Dozen: Fun one. The naive continuation is to recover the whole queen that Black is down. However, 39 ... f2 threatens two different mates. White only has two tries to defend against both, and neither 40 Rg1 nor pushing the h-pawn happens to work. |
|
| Jan-14-20 | | saturn2: 39...f2 threatens fxe1, Bxg2 mate and f1+
40. Qxe4 fxe1Q
40. Ra-f1 Bxg2 mate
40. Rxe4 fxe1Q 41. Qg1 Rxg1 mate |
|
| Jan-14-20 | | Agferna: 39 ...Qg1+ 40 Rg1 Rg1+ 41 Qg1 f2+ was just as effective and more forcing checking all the way. Cheers |
|
| Jan-14-20 | | Agferna: Sorry, I meant 38....Qg1+. Cheers |
|
| Jan-14-20 | | stacase: 39...Rxg2 doesn't say check and doesn't do very much, well yes it wins the Queen, but 39...f2 does a lot more. One of those little sayings that pop up when you post says, "When you see a good move, look for a better one." Yes, 39...f2 is way better. Mate is threatened two ways, and White can't defend both. So far the pinned piece seems to be the trend this week. |

| Jan-14-20 | | Walter Glattke: 39.-fxg2+ 40.Kg1 Re8 draw, 39.-Rxg2 also wins, 40.Rxe4 not 40.-Rf2, but 40.-f2 41.Bxg8 fe1Q+ 42.Kxg2 dxe4 |

 | | ajk68: 38... Qg1+ would have worked too. I like that continuation better as it is forcing - no alternative lines to calculate. |

 | | Sally Simpson: Nice and simple Tuesday POTD. The '(quick)' in the banner was not used in this game from the same event. Speelman vs Kasparov, 1988 Originally 'Rapid Chess' was called 'Active Chess' but this was dropped. The event was won by Kasparov.

 | | keypusher: <SamAtoms1980: If it were me I would have set the puzzle one move back. 38....Qg2+ 39.Qxg2 f2> Agree. I liked this, though. There can't be too many puzzles where you can take the enemy queen with check. |
|
| Jan-14-20 | | zb2cr: 39. ... f2 renders White defenseless.
E.g., 40. Qxe4, fxe1=Q#. Or 40. Rf1, Bxg2#. Or 40. h3, Rxg2; 41. Rf1, Rg1+; 42. Kh2, R8g2#. I note that <agb2002> has done a thorough job of enumerating more defensive tries and responses. |

| Jan-14-20 | | Damenlaeuferbauer: After long pondering, my old Ukrainian-Belgian friend Mikhail, who worked as second both for G. Kasparov and V. Anand and played for SV 03/25 Koblenz in the highest German league, finally found the subtle, study-like move 39.-,f2!, after which white is paralyzed and completely lost. |
|
| Jan-14-20 | | Ratt Boy: My first thought was 39.♕h3+ ♖h7 40.♕xh7+ ♔xh7 (40…♗xh7 41.♗xg8 f2 42.♖f1 ♗e4+ 43.♖xe4±} 41.♗xg8+ ♔xg8 42.♖xe4, and Black has no threat of …f2+. Then, of course, I saw that it was Black to move. Seems Ljubo isn't winning this one, after all. |

| Jan-14-20 | | TheaN: A similar combination was featured not too long ago, I think this one was linked to. I'm a bit baffled why Gurevich puts time into calculating 38....Qg2+, and misses 38....Qg1+. Normally I'm not a fan of the <this is faster> crowd as it's usually incorrect or irrelevant. In this case however, it can be posted as '38....Qg1+ followed by Rxg1+, f2+ and Bxg2#'. No alternatives whatsoever. In his defense, the game line's probably more interesting as after 39....f2, it shows that even without check the advanced pawn can become mightier than the Queen. |

| Jan-14-20 | | SamAtoms1980: Yeah, and now I see why the puzzle was set at the 39th. 38....Qg1+ is an alternative solution and since only checks are present, easier on the cognitive apparatus. |
|
Jan-14-20
 | | eternaloptimist: I figured this puzzle out quickly. Gurevich’s ♗ that pinned Ljubojevic’s ♕ is the key to solving it. |

Quite elegant, I'd say. |
