| Dec-24-22 | | Brenin: Black has a free P capture with 18 ... Rxe3, since 19 fxe3 Bxe3+ wins the R on c1. White can disrupt this plan with 19 b4, but then Black has 19 ... Rxf3 20 bxc5 Rf6, and he is still up by a P. This seems rather easy for a Saturday, so what am I missing? |

| Dec-24-22 | | Mayankk: I saw the 18 ... Rxe3 tactics almost immediately and how Black emerges Q+2P versus RB up since 19 fxe3 Bxe3+ forks the King and c1 Rook. 20 Kf1 Rxc1 21 Qxc1 Bxc1 22 Rxc1 follows leading to an easy Black win. However if White doesn't oblige with 19 fxe3, it gets tricky and into Saturday domain... |

 | | An Englishman: Good Evening: Also felt a little easy for a weekend puzzle--after all, I solved it, unless Black missed an even better line. After 12.0-0, White looked better, thanks to his lead in development and the Nd7 blocking Bc8. Sargissian did well to seize the initiative so quickly from that position. |

| Dec-24-22 | | mel gibson: I saw the first ply straight away as it was very cheeky
to offer a Rook sac - if it was taken then White was in trouble. Stockfish 15 is calling it a draw:

So - if the Rook was accepted?

 | | perfidious: This strikes me as being more an actual game position than a true POTD, once one realises that after 18....Rxe3, White must go in for the adventure of 19.b4 Rxf3 20.bxc5, after which he is down a pawn, but the position is far from clear--at least to this set of human eyes--as opposed to the all-seeing silicon monster. |

| Dec-24-22 | | agb2002: The white king on g1 and the rook on c1 suggest 18... Rxe3: A) 19.fxe3 Bxe3+ and 20... Rxc1 wins decisive material. B) 19.Rxc5 Rxe1+ and 20... Nxc5.
C) 19.b4 Rxf3 20.gxf3 (20.bxc5 Rf6) 20... Bd4 recovers the exchange. D) 19.Bh7+ Kh8 doesn't seem to improve anything for White. E) 19.Bc3 Re8 keeps the pawn (19... d4 is interesting). |

| Dec-24-22 | | King.Arthur.Brazil: The combination is easy to foresee: 18...♖xe3 19. fxe3 ♗xe3+ 20. ♗f2 ♖xc1+ 21. ♕xc1 ♗xc1 22. ♖xc1, where Black has a ♕+2♙ for ♗+T with real advantage.
The strong answer 19. b4 requires also a conter-attack sequence: 19...♖xf3 20. gxf3 ♗d4 21. ♖xc8 ♕xc8 22. ♗f5 ♗xa1 23. ♕xa1 ♕c6 24. ♗xd7 ♕xd7 when Black has only 1 ♙ of advantage and the previewed result is tie due to opposite colors bishops, as in the own game. The King prefers the sequence: 22...♘xd3 23. ♕xd3 ♖xc1 24. ♖xc1 axb5 25. ♕xb5 ♗a6 26. ♕b2 d4. It seems that Black cannot avoid the opposite colors bishops, but I think this position seems better. Maybe, Black was tired from calculations of the previous moves and the remaining moves doesn't seem so strong as the others. Happy Cristmas, everybody. |

| Dec-24-22 | | Brenin: <KAB>: In your preferred line (deviating from the game with 22 ... Nxd3) I think that White does better with 26 Qa5, or even Ba5, than with Qb2. Unlike in most endgames, here the player with an extra P wants to keep the heavy artillery on the board, to avoid having just opposite Bs. If he wants to avoid Q exchanges White will have to allow Black to move his pieces onto more active squares. Whatever he does, this looks like a draw, making this a rather unsatisfying POTD. |
