May-15-19		Delboy: The position where white plays the sacrificial 14. Nxd5 and 16. Rxe7 arises from a well-known opening, so I wonder how much of Adorjan's play was 'book'. Still, it is an impressive attack to watch

Sep-30-19		fredthebear: Stockfish notes explain that the alternative 16...QxRe7 was better than 16...KxRe7? as actually played. Either way, White stands better after the rook sacrifice w/check. Both White rooks inflict checks from e7. Stockfish says both colors made mistaken pawn moves on the 24th. Still, a fun king hunt w/a couple possible finishes.

Feb-26-23		Brenin: White is a piece down, but has attacking chances. The 'sac' 16 Rxe7+ is obvious. If 16 ... Qxe7 then 17 Qxa8+ regains the piece with a slight advantage. If 16 ... Kxe7 then 17 Bg5+ f6 18 Re1+ Kf8 19 Bf4, threatening Bd6+, leaves Black in trouble.

Feb-26-23		Brenin: After 16 Rxe7+ Kxe7 17 Bg5+ f6 18 Re1+ Kf8 19 Bf4 Black's only reasonable move is 19 ... g5. Then 20 Bd6+ Kg7 21 Re7+ Kh6 (Kg6 22 Qf7+ is worse) 22 h4 looks grim for Black.

Feb-26-23		vajeer: Hmmm...feels a bit strange as a puzzle given that the best defense is leaving White with only a small advantage. And with opposite color bishops on the board not sure if it can be enough to win (at least with a human brain!)

Feb-26-23		al wazir: I found white's first three moves but looked at only the 16...Qxe7 line, not 16...Kxe7, the move played.

Feb-26-23		jrredfield: I saw 16 Rxe7+ right away, seeing that Black either loses castling rights or the corner rook depending on 16 ... Kxe7 or 16 ... Qxe7. It seemed to me when playing this out a few more moves that White was gaining a big advantage positionally, yet when I checked with the engine later, it shows 16 Rxe7+ close to a draw which seemed puzzling. But then I saw that prior to White's 16th move, Black was ahead by a piece. Black was certainly in the game, but allowed the King to be pushed around too much and become an opportunity for White to gain material with forks, and too much presence around the Black King.

Feb-26-23		mel gibson: I didn't get it. Stockfish 15 is calling it close to a draw: 16. Rxe7+ (16.

Feb-26-23		An Englishman: Good Evening: Saw the first 6 moves of the game continuation and knew Black could not survive, but 16...Qxe7; 17.Qxa8+,Qd8; 18.Qxd8+,Kxd8 looked a better defense. White still has to play this line anyway to regain material. Overall, another 5/7 week, flubbing Friday and Saturday. On to Monday.

Feb-26-23		outplayer: I saw it easily. The first three moves.

Feb-26-23		outplayer: <Brenin> You are amazing.

Feb-26-23		scormus: A long combination! Following the text I was OK until 22. I couldn't see the way to finally slay the beast. I rashly picked 22 Qf7?? after which ... Qf8 would kill W's attack. Another nearly. I didn't really expect 16 ... Qxe7! I suppose I thought it wouldn't have been the story <outplayer <Brenin> ....> Yes. The King.

Feb-26-23		sorso: white to play 14?,would be better

Feb-26-23		Brenin: <sorso: white to play 14?,would be better>: Maybe, but White's N on d4 is en prise, with only e2 as a safe square, and 14 Nde2 d4 15 Nd5 (or Ne4) Nxd5 16 Qxd5 0-0 is clearly in Black's favour, so the key move 14 Nd5 is almost forced. In the game, after 14 Nd5, Black avoids all trouble by ignoring the N on d4 end playing 14 ... Nxd5 15 Qxd5 0-0.

Feb-26-23		chrisowen: I awe it is both go jiffy it is z lud c Rxe7+ arrive grog fab abacus it is auld bereft it is ze Rxe7+ go;

Feb-26-23		agb2002: White is one bishop down. Black is about to castle, assuming it is legal. The black queen is overburdened with the defense of a8 and e7. Hence, 16.Rxe7+ Kxe7 (16... Qxe7 17.Qxa8+ Qd8 18.Qxa6 wins a pawn with a much better position) 17.Bg5+ f6 18.Re1+ (18.Bf4 Be6) 18... Kf8 (18... Be6 19.Qxe6+ Kf8 20.Bf4 g5 21.Bd6+ Kg7 22.Be7 looks winning) 19.Bf4 g5 (19... g6 20.Bh6#) 20.Bd6+ Kg7 21.Re7+: A) 21... Kg6 22.Qf7+ A.1) 22... Kh6 23.Qxf6+ Kh5 24.Qf7+ Kh6 (24... Kg4 25.Re4#; 24... Kh4 25.Bg3+ Kg4 26.f(h)3# or 26.Re4#) 25.Be5 Qg8 (25... Qxe7 26.Bg7#) 26.Bg7+ Qxg7 27.Qxg7+ Kh5 28.Rxd7 wins decisive material. A.2) 22... Kf5 23.Re5+ A.2.a) 23... Kf4 24.Qh5 Bg4 (24... fxe5 25.Qf3#; 24... g4 25.Re3#) 25.Rxg5+ Ke4 26.Qxg4#. A.2.b) 23... Kg4 24.h3+ Kf4 25.Qh5 as above. B) 21... Kh6 22.h4 B.1) 22... Bb5 23.hxg5+ looks very good for White. For example, 23... fxg5 24.Qe6+ Kh5 25.Qf7+ and mate soon. B.2) 22... Qf8 23.hxg5+ (probably better than 23.Rxh7+ Kxh7 24.Bxf8 Rhxf8 25.Qxd7) followed by Rxd7 should be winning. B.3) 22... Qg8 23.Qxd4 looks good for White. For example, 23... Be8 24.Qxf6+ Qg6 25.hxg5+ Kh5 26.Qf3+ Kxg5 27.Bf4+ and mate next. Or 23... Bc8 24.Qxf6+ Kh5 (24... Qg6 25.Qxh8 Qxd6? 26.Qxh7#) 25.Rg7 wins. C) 21... Qxe7 22.Bxe7 Bb5 23.Qxd4 Rhg8 24.Qxf6+ looks winning.

Feb-26-23		King.Arthur.Brazil: t seems immediate the sacrifice is the best option, since the ♕ capture is bad, directly with the line: 16. Rxe7+ Qxe7 17. Bg5 f6 (17.Qxa8?? Qe1#) 18. Qxa8+ Qd8 19. Re1+ Kf7 20. Qd5+ Kf8 21. Bf4 etc. If Black captures the ♗: 17... Qxg5 18. Qxa8+ Ke7 19. Qxh8 Bh3 20. Re1+ (the line of Kd6 is similar to the following) Kd7 21. Qe8+ Kd6 22. Qb8+ Kd5 23. Qb7+ Kd6. 24. Qxa6+ Kd7 25. Qb7+ Kd6 26. Qb6+ Kd7 27. Qxd4+ etc. White capture Black ♙ or win this ♕ (I love it!). Black Lose easy. So, now remains the most unwanted move for Black: 16... Kxe7 17. Bg5+ f6 18. Re1+ Kf8 19. Bf4 g5 20. Bd6+ Kg7 21. Re7+ Kg6 22. Qf7+ Kh6 23. Rxd7. I guess that White has the better chances. In the case of 18... Be6 19. Qxe6+ Kf8 20. Bf4 g5 21. Bd6+ Kg7 22. Bf7... and Black will lose material (maybe the ♕}!!! lgs.

Feb-27-23		Check It Out: Same as <scormus> I saw all the way to 21 but couldn't pick out 22.h4.
