 | | Honza Cervenka: Pretty game. If 17...dxe4, then 18.Rg1+ Kh8 19.d5 Bxd5 20.Bd4 Nd7 21.Nxd5 cxd5 22.Nf3  |
|
| May-20-23 | | Brenin: White's d- and f-pawns are itching to advance, allowing his DSB into the game. They are blocked by Black's d- and f-pawns, but the capture 17 Bxe4 forces one of those to recapture, so that White has either d5 or f5 available. In either case, Black's position looks very weak, with moves like Rg1+ and Qb3 adding to his difficulties. |

Stockfish 15 chooses a different ply to the game: 17. Nxe4
(17. Nxe4 (Nc3xe4 f5xe4 f4-f5 Be6xf5 Rf1xf5 Qf6xf5 Qc2-g2+ Kg8-h8

| May-20-23 | | jrredfield: After 5/5 so far this week, my luck ran out. I went with 17 Qg2+ Kh8 18 Bxe4 Rg8 which, while I later learned, is a winning move, 17 Nxe4 is best. After 17 Nxe4 fxe4 18 f5 Bxf5 19 Rxf5 Qxf5 20 Qg2+ Kh8 21 Rf1 Black has to retreat and cope with a full scale onslaught by White on the Kingside. |

 | | master8ch: Lasker claims 19...Bxg4 is forced, giving 19...Qe6 as the only move to briefly guard the Bishop at f5. I claim 19...Qg6 wins for Black. I see no way for White to take timely advantage of Black's Q & K on the g-file, and if 20.Nh6+ Kh8, 21.Qf2, as in the game, Black has 21...Nd7, giving his first rank plenty of protection and forcing 22.Nxf5 (before the Bishop moves to safety.) Then Black has 22...Qh5, threatening a seemingly unstoppable 23...Rxf5, since the White Queen is overloaded. For example: 23.Ng3 Rxf2, 24.Nxh5 Rxh2+, 25.Kg1 Rg8+, 26.Ng3 Bxg3, and White will lose still more material. |
|
| May-20-23 | | sudoplatov: Instead of 22.Nf5 (in the 19...Qg6 line), try 22.Nf5. Failure to capture with the Rook leaves White at least a Piece up and 22...Rf5 is met by 23.Rg1. (Thanks to Stockfish). |
|
| May-20-23 | | Honey Blend: My game plan was 17. ♕b3, attacking the weak b7 while lining up the queen up along a2-g8 diagonal. If 17. ... b6 then 18. cxb6 ♗xb6 19. a4 preparing a5 intending to infiltrate with ♕b7, but that looked too positional to be a solution to a Saturday puzzle. |
|
| May-20-23 | | Cecco: After 19 ... Qg6 can follow 20 Nh6+ Kh8 21 Rxf5 Rxf5 22 Rg1 + -. But indeed Lasker's comment seems dubious because after 19...Qe6 20 Nh6+ Kh8 21 Qf2 can follow 21...Nd7 22 Nxf5 Rf7 and it is not clear that white can keep the piece lead. Much stronger seems 21 Qg2 which really leads to a piece gain. |

 | | scormus: Didn't get much of this. Picked 17 Nxe4 fxe4 18 f5, instead of Bxe4 etc, and never got properly on track with the text. I'll take some satifaction from <mel's> SF line. |

| May-20-23 | | agb2002: The first idea that comes to mind is 17.Qb3, threatening Qxb7 and x-raying the black king: A) 17... Bc8 18.Bxe4 fxe4 19.Nxe4 wins a pawn.
B) 17... Bxe5 18.fxe5 Qf7 19.Bh6, followed by Rg1, looks very good for White. C) 17... b6 18.Bxe4
C.1) 18... dxe4 19.d5, with the double threat dxe6 and Rg1+ combined with Bd4, looks very good for White. C.2) 18... fxe4 19.f5
C.2.a) 19... Bf7 20.Bg5 Qg6 (20... Qxg5 21.Rg1) 21.Rg1 Qh5 22.Bd8+ wins a piece at least. C.2.b) 19... Bxe5 20.fxe6 Qxf1+ (20... Qe7 21.dxe5) 21.Rxf1 Rxf1+ 22.Kg2, with the double threat Kxf1 and dxe5. C.2.c) 19... Bxf5 20.Nxd5 looks winning (20... cxd5 21.Qxd5+ and 22.Qxa8). |

Bxh5 26. Nxg8? Rxg8 and Black appears to be winning. |
|
| May-20-23 | | King.Arthur.Brazil: I failed in the POT. I though about the moves: 17. Rg1+ Kh8 18. Rg5 Nd7 19. Rag1... I didn't find anything concrete. Maybe, Rubstein committed some error next, I don't know. |

|
| May-21-23 | | Vyvorante: why is the pgn wrong, this is the second time I come to this site and found an error... like here: Again forced. If 19...Qe6 20.Nh6+ and 21.Qf2 would win the bishop. how does the Nc3 jump all the way to the h file? |

 | | perfidious: This POTD could very easily be a Sunday, given its complexity and the necessity to be aware of Black's counterattack. Lasker gives 22.Rg1 an exclam, but it seems forced and had to be foreseen before Freymann embarked on his conception, a wily one worthy of his great opponent, who would win the event despite this setback, going on to win the next four games. |
