Aug-26-05		teme: Wow amazing game.

Jul-07-22		Brenin: Black's P on f5 looks tempting, but I don't think any of the captures there lead anywhere. As in yesterday's POTD, a quiet Q move seems the best for White, namely 42 Qd2, heading for g5 or h6 where it will be hard for Black to avoid mayhem on his weak dark squares.

Jul-07-22		al wazir: I spent a lot of time on 42. gxf5 exf5 43. Qg4, and now if 43...Re3+ then 44. Ng3 (44. Rf3 Nf4+; 44. Kh2 Qd6+) Rxc3 45. Rxf5+ Qxf5 46. Qxf5+ Kg7 47. Qd7+, and now white can win a ♖ with a ♕ fork, e.g., 46...Kg7 (46...Kh6 Qd2+) 47. Qd7+ Kg8 48. Qd5+ Kg7 49. Qd4+. But I'm not sure that's black's best line of defense.

Jul-07-22		newzild: Tough one today - quiet moves are often the hardest to find.

Jul-07-22		Honey Blend: 42. ♕e4 to pile up on f5 seems like a pretty reasonable alternative too.

Jul-07-22		boringplayer: I found 42. Qd2, but thought 43.Bf6 was a sufficient reply to 42...Qe7. Alas, now black can take the g pawn... No points for me :(

Jul-07-22		steinitzfan: Too difficult for me. In fact, the mating sequence at the point where Black resigned gave me a major workout.

Jul-07-22		perfidious: In such an open position, it is tempting to search for forcing lines to get at Black's king, but I saw none. The one chance to get at the little bugger is on those dark squares. That said, I did not suss out the solution.

Jul-07-22		mel gibson: I wasn't sure and I didn't even consider the correct move. Stockfish 15 agrees with only the first ply: 42. Qd2 (42. Qd2 (♕e2-d2 ♖e8-d8 ♕d2-h6 ♔f7-e7 g4xf5 ♔e7-d7 f5xg6 h7xg6 ♘h5-g3 ♔d7-c6 ♕h6-g7 ♔c6-b5 ♖f1-b1+ ♔b5-a6 ♖b1xb8 ♖d8xb8 ♗c3-d4 ♖b8-b7 ♕g7xb7+ ♔a6xb7 ♗d4xc5 ♔b7-c6 ♗c5-b4 ♔c6-b5 ♗b4-c3 ♔b5-c5 ♘g3-e4+ ♔c5-c6 ♔h3-g4 ♔c6-c7 ♘e4-g5 ♔c7-d7 ♔g4-h3 ♔d7-d6 ♗c2xg6 e6-e5 ♔h3-g4 e5-e4 ♗g6xe4 ♔d6-e7 ♔g4-f3 ♔e7-d7 ♗e4-g6 ♔d7-c7 ♔f3-g4 ♔c7-c6 ♗g6-e8+ ♔c6-d5 ♗e8-f7+ ♔d5-c6 ♘g5-e4) +14.09/34 410) score for White +14.09 depth 34. If I get Stockfish to play from the text in the 2nd ply 42... Qe7: 42. Qd2 Qe7 43. Bxf5 (43.

When Black resigns at move 46 it's mate in 6: 46. Bb4+ Kxe6(♔e7xe6 ♘h5-g7+ ♔e6-e5 ♖f1-f5+ ♔e5-e4 ♕d2-e2+ ♔e4-d4 ♕e2-d1+ ♔d4-e3 ♕d1-f3+ ♔e3-d4 ♗b4-c5+) -M6/169 14 1-0 White wins _ mate in 6.

Jul-07-22		mel gibson: Note: I did consider 42. Nf6 and 42.Ng7 which attacks the Rook on e8, and those moves still win but are not as powerful as the correct move.

Jul-07-22		Brenin: Another advantage of 42 Qd2 is that, in addition to threatening to invade on the weak dark squares of Black's K-sde, by moving the White Q off the e-file, where it is vulnerable to the R on e8, it makes the captures 43 B(or g)xf5 exf5 much more dangerous for Black, as in the game continuation.

Jul-07-22		Teyss: <steinitzfan> Same 😕

Jul-07-22		saturn2: After a while I found 42. Qd2 threatening Qh6. and gxf5 (after exf5 the queen is no longer attacked by the rook and Rxf5 wins the queen)

Jul-07-22		saturn2: I did not anticipate 42...Qe7 and the check Qh4. However it does not help black. White complicated up by 43.Bxf5. 43.Qh6 was enough ...Rg8 and only now 44.Bxf5. But 44 gxf5 were a loser because it opens the g file.

Jul-07-22		parch: 42.Qd2 Δ 43.♕h6 (42.gf5? ef5 43.Be4 Rb1 44.R:b1 R:e4 ) 42...Ne7 43.Qh6 Rg8 44.Ng7 R:g7 45.Q:g7+ missed 42...Qe7

Jul-07-22		TheaN: Tough Thursday because of the alternatives to consider. After a long time, I realized White has just one piece misplaced, the queen, and her vulnerability leads to all kinds of complications. Then, moving the queen first becomes a serious option. <42.Qd2 +-> and good luck to Black. Qg5, Qh6, gxf5, Bxf5 and if necessary, Qd7+. At the start it's already 2B vs R+3P, and the bishops show their power after Qd2: blocking as good as any progressing move by Black. Black's attempt, <42....Qe7!?> is actually kind of smart, to relay play to the relatively weak White king, but <43.Bxf5!> protects g4, so 43....Qh4+ 44.Kg2 +- leads to nothing. Interesting game.

Jul-07-22		ChessHigherCat: Saw the solution instantly but it was for the wrong puzzle. No.seriously, the definition of a "quiet move" seems to be "none of the obvious or even promising lines", but of course, according to the heuristic principle, you have to exhaust those before finding the one right line, meaning it's pro (IM/GM) stuff demanding great endurance and persistance (hard work). Could I outplay 2680 Lautier? No way in hell, but the combination is still iinteresting. My user name is just a pun on the "Chessire cat" by the way, it's not a claim to be the best chessplayer in the world.

Jul-07-22		GlennOliver: "<steinitzfan> Too difficult for me. In fact, the mating sequence at the point where Black resigned gave me a major workout." Well said, I concur. Kudos to anyone who did manage to work out the winning endgame sequence without machine assistance.

Jul-07-22		Steve Holloway: I only considered 42.gxf5 exf5 43.Qg4 Re3+ 44.Ng3 Kg8 45.Rxf5 winning

Jul-07-22		agb2002: White has the bishop pair for a rook and three pawns. The dark squares around the black king are very weak. This suggests 42.Qd2: A) 42... f4 43.Bxg6+ A.1) 43... Kxg6 44.Nxf4+ followed by Nd3+ wins the queen. A.2) 43... hxg6 44.Rxf4+ Kg8 (44... Ke7 45.Bf6+ and 46.Be3+ wins the queen) 45.Nf6+ and Nd7+ wins the queen. B) 42... Qf8 43.gxf5 is winning. C) 42... Qe7 43.Bxf5 (43.Qh6 Qh4+) C.1) 43... exf5 44.Rxf5+ Kg8 45.Nf6+ and Nd5+ wins decisive material. C.2) 43... Qh4+ 44.Kg2 exf5 45.Rxf5+ Ke7 (45... Kg8 46.Qd5+ Re6 47.Qxe6#) 46.Bf6+ wins decisive material. D) 42... Qd5 43.Rxf5+ wins decisive material (43... exf5 44.Qxd5+). E) 42... Ke7 43.gxf5 exf5 (due to Bf6+ and f6+) 44.Rxf5 is winning. F) 42... Re7 43.gxf5 Nf8 44.fxe6+ Ke8 (44... Kg8 45.Nf6+ and 46.Ne4+) 45.Ba4+ wins decisive material. ----- Other alternatives like Nf6 and Ng7 look advantageous for White but weaker than Qd2.
