| Aug-10-20 | | Walter Glattke: White has 2 pawns more an wins with 29.Qxd7+ Kxd7 30.Nc5+ and 31.NxQ we like Mondays |
|
| Aug-10-20 | | agb2002: White has a knight and two pawns for a bishop.
Black threatens Rxa7.
White can win the rook with 29.Qxd7+ Kxd7 30.Nc5+. |

| Aug-10-20 | | mel gibson: Good beginners puzzle. |

 | | Alex Schindler: free rook & simplification. Not bad for a Monday's work |
|
| Aug-10-20 | | Brenin: Nice Monday puzzle. Having sacrificed five tempi to win a pawn, Black took greed a step too far with 14 ... Bxa4, when a developing move such as Rg8 or Be7 would have been wiser. White's R sac 19 Rxe6 was spectacular, and ultimately successful, but wouldn't 19 Qd5, threatening mate on d7, have been quicker, e.g. 19 ... Rc7 20 Rxe6+, with mate to follow? |
|
| Aug-10-20 | | saturn2: Estrin considered Morphy as the greatest ever.
Black neglected opening principles in the first 9 moves which Estrin punished in a Morphy way. |
|
| Aug-10-20 | | Nullifidian: 29. ♕xd7+ ♔xd7 30. ♘c5+ wins back the queen and puts white a rook up. The bishop can't capture because of the pin. Black really can't refuse the temporary sac either because 29... ♔b8 also loses the bishop, and the capture of the bishop is the start of a mating sequence. |

| Aug-10-20 | | et1: Magic. |
|
| Aug-10-20 | | TheaN: Somehow my eye fell on 29.Nc5 immediately and was about to settle on it until I noticed the queen's en prise. Mind that after 29....Qe1+! (Rxa7 now is worse) 30.Rxe1 Rxa7 31.Na4 ± White's of course winning, but that means White was winning when the puzzle started and didn't make any progress. So, switch the moves (in the previous line we didn't play it but intended) <29.Qxd7+> and Black's forced to <29....Kxd7 30.Nc5+ +-> and White comes up a rook instead. |
|
| Aug-10-20 | | goodevans: 15...Qxa4? was foolhardy and 17...Qxa2? just compounded the error (18.Nxc6 would be far less troublesome after 17...Qa3). Whilst 19.Rxe6+ undoubtedly had shock value, the simpler 19.Qd5 would probably have won quicker. |
|
| Aug-10-20 | | zb2cr: 29. Qxd7+ does double duty, both repositioning the King for a Knight fork and putting in place a pin of the Black Bishop. After 29. ... Kxd7; 30. Nc5+ White will be a Rook ahead, with 2 extra connected passed Pawn. |
|
| Aug-10-20 | | areknames: < Somehow my eye fell on 29.Nc5 immediately and was about to settle on it> I actually DID settle on it after a very exhausting day. It's a terrible blunder - I didn't even notice the queen was en prise - but remarkably it still wins fairly comfortably! |

| Aug-10-20 | | Damenlaeuferbauer: After long thinking (because he was primarily a mail chess player), the 7th correspondence chess world champion Jakov Estrin finally found the nice combination 29. Qxd7+!,Kxd7 (29.-,Kb8 30.Qxd6+ +-) 30.Nc5+ with 31.Nxe4 +- to follow. BTW, a former girl friend of mine played the Katalymov variation of the Sicilian defense (1.e4,c5 2.Nf3,b6!? 3.d4,cxd4 4.Nxd4,Bb7) regularly in the first half of the 1980s with not worse results than in the main lines (Najdorf, Dragon, Scheveningen, and Sveshnikov at that time). |

 | | gawain: A deadly knight fork which is quite Mondayish. But Qxd7+ has to come first. |
|
| Aug-10-20 | | Walter Glattke: I found no options to 14.-Bxa4, good for white was 14.-Bxg2 15.Kxg2 Rg8+ 16.Kh1 Qg5 or
14.-Rg8 15.Bxc6 Nxc6 16.Rd5 Qc7 17.Qh5 |

| Aug-10-20 | | TheaN: <Brenin: Nice Monday puzzle. (...) White's R sac 19 Rxe6 was spectacular, and ultimately successful, but wouldn't 19 Qd5, threatening mate on d7, have been quicker, e.g. 19 ... Rc7 20 Rxe6+, with mate to follow?> Yes. I do have to admit that spotting 19.Qd5 Rc7 (Bc5 best, 20.Qxd7+ Kf8 21.Qxc8+ +-) 20.Rxe6! Be7 (fxe6 21.Qh5#; dxe6 21.Qd8#) 21.Rxe7+ Kf8 22.Qxf7# is <not> a trivial combination as the mating pattern from h5 is rather hidden. Move 20 in that case would have sufficed for a Monday on its own. Interesting. |

| Aug-10-20 | | messachess: Nice little puzzle. |

| Aug-10-20 | | RandomVisitor: White offers a piece sacrifice with 14.Rad1, but black can likely decline with 14...Rg8 and obtain a good game:

| Aug-10-20 | | Brenin: So Katalymov played the Katalimov variation of the Sicilian. What a coincidence! I wonder whether they knew each other. His record with it on CG is not good: this game and an equally quick loss to Vasiukov. |

| Aug-10-20 | | RandomVisitor: After 14.Rad1, arguably the critical point of this game, black also had 14...Ra7, where in this critical variation from a 2 hour run, black is holding his own:
