|May-11-18|| ||agb2002: White is one pawn down.
Black threatens Bxh6 and gxf5.
The position of the black queen and the rook on d8 suggest 25.Bxe5:
A) 25... Bxh6 26.Nxh6+
A.1) 26... Kf8 27.Bxc7 wins a piece.
A.2) 26... Kh8 27.Bxf6#.
A.3) 26... Kg7 27.Bxc7
A.3.a) 27... Kxh6 28.Nxf7+ Kg7 29.Nxd8 + - [R+B+P vs n].
A.3.b) 27... Rdc8 28.Bxc8 Rxc8 29.Bxb6 axb6 30.Nhxf7 + - [R+N+P vs b].
A.3.c) 27... Nbd5 28.Bxd8 Rxd8 29.Ng4 + - [R].
B) 25... Qxe5 26.fxe5 Bxh6 27.Nxh6+ Kg7 (27... Kf(h)8 28.exf6 + - [N]) 28.exf6+
B.1) 28... Kxh6 29.Nxf7+ Kh5 30.Re5+ g5 31.Rxg5#.
B.2) 28... Kxf6 29.Ng4+ Kg7 (else 30.Re5#) 30.Re7 + - [N vs p].
C) 25... gxf5 26.Qxf6 wins.
D) 25... Nbd5 26.Bxc7 Bxh6 27.Nxh6+ Kg7 28.Bxd8 Rxd8 29.Nhxf7 + - [R+P].
|May-11-18|| ||Eduardo Leon: <ChessHigherCat> Your line 25.♗xe5 ♕xe5 26.♗xf6 makes no sense, because 25...♕xe5 captures the very same bishop that's supposed to capture the ♘f6.|
However, 25.♗xe5 ♕xe5 26.fxe5 ♗xh6 27.♘xh6+ ♔g7 28.exf6+ ♔xh6 29.♘xf7+ wins an exchange, and, with it, the game.
|May-11-18|| ||Walter Glattke: White threatens mate, e.g.Bxf6 and Nh6, black can play 25.Bxe5 Bxh6 26.Ne7+ Kg7 27.Bxd8 or 25.-Qxe5 26.Rxe5 Bxh6 27.Nxh6+ Kg7, rule 2 says, "both players move alternately" - changing chessmen for chessmen. 25.-Qxe5 26.Qxf8+? -+|
|May-11-18|| ||Walter Glattke: I just see, 26.fxe5 instead Rxe5 is better.|
|May-11-18|| ||ChessHigherCat: <Eduardo Leon> Sorry, I meant this:|
25. Bxe5 Qxe5 26. fxe5 Bxh6 27. Nxh6+ Kg7 28. exf6+ Kxh6 29. Nxf7+ Kh5 30. Re5+ g5 31. Rxg5#
It doesn't just win the exchange, it mates, right?
|May-11-18|| ||ChessHigherCat: In this line white just wins a piece, but it's hard to believe there's nothing better:|
25. Bxe5 Qxe5 26. fxe5 Bxh6 27. Nxh6+ Kg7 28. exf6+ Kxf6 29. Ne4+ Kg7 30. Ng4
|May-11-18|| ||al wazir: After 25. Bxe5 black captures the white ♕, but in the process allows himself to be attacked by a swarm of minor pieces. I saw the key move and the ♕ sac, but missed some details. |
Better for black but still losing is 25...Qxe5 26. fxe5 Bxh6 27. Nxh6+ K moves 28. Nhxf7.
If 25...gxf5, then 26. Qxf6. (Not 26. Bxc7 Bxh6 27. Bxd8 Rxd8 28, Bxf5, and white only has ♖+♙ vs. ♗+♘.)
|May-11-18|| ||gofer: <Eduardo Leon>: <However, 25.♗xe5 ♕xe5 26.fxe5 ♗xh6 27.♘xh6+ ♔g7 28.exf6+ ♔xh6 29.♘xf7+ wins an exchange, and, with it, the game.>|
29 Nxf7+ is much much more than just <winning an exchange>. It is mate in two more, which means that 27 Nxh6+ wins a piece, because black cannot play 27 ... Kg7, with the aspiration to take Nh6.
|May-11-18|| ||Mayankk: Nice puzzle. Saw most of it - starting with the fact that Bxe5 should be the first move since It makes the Queen hide for cover (Qxe5 is disastrous for Black). After that I did cheat in a way to see Black’s response i.e. Qd7. The rest of the moves were then clear to me, Bxf6 for a Queen sac and mate shortly afterwards.|
This is how I would have played in a real game - just Bxe5 first since it’s a strong move in any case and then figure out the sparkling tactics once Black responds.
|May-11-18|| ||leRevenant: Friday Q-sac (Yawn)|
|May-11-18|| ||Cheapo by the Dozen: The main trick was to realize there were a bunch of lines in which mate didn't seem to happen, and then to check that a nice material advantage happened in those lines instead.|
|May-11-18|| ||Richard Taylor: I didn't find this. I thought Bxe5 was too obvious (not quite seeing it was a mate as in the line given). So I thought it was 25. fxe5 but that doesn't work.|
Very nice mate though by this player who seems to have only a couple of games up.
|May-11-18|| ||Richard Taylor: <leRevenant> yawns! But it was a complex position and the mate is very beautiful. |
Quite a gem.
|May-11-18|| ||takchess: Well I got the B x e5 part as Black has the right pieces to flood the zone. I didnt see the Queen was en prise....As Purdy said: sometimes it is better to look around than to look ahead.|
|May-11-18|| ||eblunt: Hayden certainly ties Winser in a knot there.|
|May-11-18|| ||mel gibson: I saw the first few moves but wasn't quite sure how to end it.|

|May-11-18|| ||morfishine: Hayden go seek|
|May-11-18|| ||Carlos0012358: 25.....Qd7 is black's suicidal blunder that accelerated an already sure death. Exchanging the Queens would have extended play.|
|May-11-18|| ||Eduardo Leon: <ChessHigherCat> <gofer> My bad! I saw that white would win at least the exchange, and abruptly stopped thinking.|
|May-11-18|| ||eblunt: < Carlos0012358:> Yes, but at best loses a piece in the exchange.|
|May-11-18|| ||njchess: Not that difficult for a Friday. 25. ♗xe5 comes readily enough as does 26. ♗xf6 with the rest being fairly easy tactics. I'm not sure if Black could have defended better. Probably, but White would still be winning.|
|May-11-18|| ||messachess: I didn't envision the last position (the rook!) As pointed out here already, exchanging queens looks better for black.|
|May-11-18|| ||Kretenos: Easy for a Friday, once you see the possibility of the bishop covering the black squares next to the king, the solution comes very naturally.|

|May-11-18|| ||landshark: Got it but it took a long time for me to settle on the game continuation, which is fairly simple. What made me pause was making sure Black didn't get too much counterplay with Rd2 at some point. Which made me consider 25 Qh4, which seemed to also win - until I finally saw 25...Nd7! which looks to stave off mate just long enough to let Black into White's position with a very disruptive ...Qb6+. Really interesting puzzle because of the range of options you have to consider -|
