| Aug-13-19 | | sfm: I wonder why Black played 20.-,f6
And funny how sensible Black moves are all an engineering of the sui-mate.23.-,bxa5 - recapturing, what else? [but the b-file is now open for the white rook] 24.-,Ra7 - rook takes part in the enforcement of the king side [but leaves the 8th rank] 25.-,0-0 - getting the king away from the middle and giving extra coverage of f6 [but the g-pawn becomes a deadly attacker] 26.-,f5 - need to cover h5 [but all of above combines into a little detail...] 27.-, no more sensible moves to play! |
|
| Aug-13-19 | | Cheapo by the Dozen: I try to solve Tuesday problems at Monday speeds. It didn't happen this time. I spent a little while trying to figure out how to get past Black's knights before realizing that the real chance lay in diverting Black's queen. |
|
| Aug-13-19 | | AlicesKnight: Same as <Cheapo>; Black castles and suddenly it's all over. |
|
| Aug-13-19 | | patzer2: For today's Tuesday puzzle solution, 27. Rb8! +- (+13.01 @ 25 ply, Stockfish 9 analysis of move 27...?) overloads the Black Queen who cannot guard both b8 and h4. Even prettier than 27. Rb8! is the strong move 25. g5!! +- (+3.17 @ 20 ply, Stockfish 9 analysis of move 25...?) which sets it up. P.S.: For an improvement for the losing side, instead of 9...h5?! 10. Be2 ± (+1.12 @ 28 ply, Stockfish 10), our Opening Explorer indicates Black has had good results with 9...0-0 = (-0.16 @ 29 ply, Stockfish 10). An instructive example of play with 9...0-0 is Black's win in N Dzagnidze vs G Sargissian, 2012. |

| Aug-13-19 | | malt: 27.Rb8 and Black can't defend h4,
27...Q:b8 28.Q:h4 |
|
| Aug-13-19 | | TheaN: I noticed that after 27.Rb8 Qxb8 28.Qxh4 will lead to mate, but thought White could speed it up with 28.Ne7+, missing 28....Rxe7. Interestingly, it changes absolutely nothing: as Black needs to vacant f8 to prevent Qh7#, it doesn't matter whether White's defending or Black's occupying e7. Black only has an additional check on e4.

Premium Chessgames Member <chessgames.com: <Sorry folks, this one slipped into the list twice. Additionally, I've become horribly confused as to which ones have been shown and which ones haven't. Our apologies if you see some "summer re-runs" for a while.

 | | gawain: I'm pleased to have seen this one quickly. Deflect the queen and mate follows soon thanks to the white pieces covering the king's escape squares e7 and f7. I don't think I've kibitzed previously on this game but I've probably seen it. |

 | | tobywan: I solved it quickly. Now you tell me I've seen it before? You think I've learned something? Nah. |
|
| Aug-13-19 | | zb2cr: The Black Queen protects h4. If it can be deflected from the defense of that spot, White will checkmate, because the White Pawn on g6 and the White Knight on d5 close the escape holes for the Black King. Therefore, 27, Rb8! to bother the Black Queen. If Black plays either 27. ... Qxb8 or 27. ... Qd7, White plays 28. Qxh4, with mate to follow. Can Black wiggle out? If 27. ... Rd7; 28. Rxd8, Rfxd8; 29. Qxh4, Nf8 covers the mating square in time, but White has 30. Ne7+, Rxe7 (forced); 31. Qxe7, Rd7; 32. Qe8 and White's advantage of Q vs. minor piece leads to a quick win. |

| Aug-13-19 | | billbarstool: Monday-like puzzle. Sack the rook gobble the h4 pawn or don't take the sac and enveloped by whites python position |
|
| Aug-13-19 | | ZonszeinP: Nice and easy
But
Paul is not dead |
|
| Aug-13-19 | | ZonszeinP: Never |
|
| Aug-13-19 | | Dr. Funkenstein: Castling (25. ...0-0) seems to lose by force, why can't black take on g5 with either piece (as we see where not taking the pawn leads). |
|
| Aug-13-19 | | Helloween: 27...Qd7 would have set one last trap to get the King out |
|
| Aug-13-19 | | Everett: Rb8 done |
|
| Aug-13-19 | | 1stboard: Can someone run through >> Stockfish << what it suggests black to play on move 25 ( instead of O-O ) ?? |
|
| Aug-13-19 | | whiteshark: <Dr. Funkenstein / 1stboard> At this point black was already lost:

| Aug-13-19 | | NBZ: <Stale.Mate> I got the move but not the pun. This may be one case where getting the pun is harder than getting the move! |
|
| Aug-14-19 | | PhilFeeley: I'm not sure I get the pun either. Who is the "Paul" in it - McCartney, maybe? Except he's not dead, and where's the pun anyway? |
|
| Jan-04-22 | | Saniyat24: Where is Paul? |
|
| Jan-06-22 | | Dim Weasel: To get the pun check this:
https://en.wikipedia.org/wiki/Paul_... |
|
| Sep-22-23 | | Ulhumbrus: It may be that with 9...h5 Keres thinks that Botvinnik's king will become a target but Keres' own king becomes a target instead. However why does Keres think that after 9...h5 Botvinnik's king will become a target? One example of a guess as to an answer is that Keres imagines a knight sacrifice on g4 eg by ...Nf6-g4+ with White's king on h2. |
