Nov-27-13		Phony Benoni: On an intital glance, saw that 21.Qh5 is answered by 21...Ng6. So maybe we should sacrifice on h7 first to prevent that? Let's see: <21.Bxh7+ Kxh7 22.Qh5+ Kg8 23.Bxf6 Ng6 24.Qh6> and mate follows. <21.Bxh7+ Kxh7 22.Qh5+ Kg7 23.Qg5+ Ng6 24.Bxf6+ Kg8 25.Qh6> and as before. <21.Bxh7+ Kh8 22.Bxf6+ Kxh7 23.Qh5+ Kg8 24.Qh8#> Looks pretty secure. Although, of course, I didn't look at 21...Kg7, the hardest and prettiest line. In other lines, it's easy to see that there is a queen check on g5 due to the pin on the f-pawn. But seeing that ...f5 is also ruled out as a defense is a bit trickier

Nov-27-13		MountainMatt: This is one of those classic Wednesday puzzles that has an obvious starting move screaming to be played, and from there is so rich with possibilities that my brain feels like an egg frying. I'll just look forward to what the greater minds here (such as Phony Benoni!) can squeeze out of it. Happy Thanksgiving all!

Nov-27-13		Infohunter: Right off it looked like a position that was screaming for a Bishop sacrifice on h7, so that is what I tried. The only thing I missed was Black's attempt to decline it, before being forced to accept it one move later. This almost, but not quite, qualifies as a Double Bishop Sacrifice game: Very similar winning idea.

Nov-27-13		starkidaway: I get that the solution in the game works, but what is wrong with 21.Qe4? Black has a couple of options: 21..... Nf5 22.Qg4+ wins 21... f5 22. Qh4 wins 21....Ng6 22.Bxf6 and it's hard for black to stop white from coming to h6

Nov-27-13		Patriot: I'm wondering if there are several moves that win here. 21.Qg4+ Ng6 22.Bxf6 Qf4 looks like a problem. 21.Qg4+ Ng6 22.d6 Qc5 23.Bxf6 looks interesting. 21.Bxh7+ Kxh7 22.Qh5+ Kg7 23.Qg5+ Ng6 24.Bxf6+ Kh7 25.Qh5+ Kg8 26.Qh6 21.Bxh7+ Kxh7 22.Qh5+ Kg8 23.Bxf6 Ng6 24.Qh6 21.Bxh7+ Kg7 22.Qg4+ Ng6 23.Qg5 Qf4 24.Qxf6+ 21.Bxh7+ Kg7 22.Qg4+ Ng6 23.Qg5 e5 is the problem. I'm not so sure about this. A very tricky Wednesday with a lot of options.

Nov-27-13		Patriot: That was MUCH harder than the usual Wednesday! I really messed up on the next to last line: 24.Qxf6+ and black wins!

Nov-27-13		M.Hassan: "Medium/Easy" White to play 21.? White is a pawn down. Black Queen is partly exposed and it is time to attack and make further exposure: 21.Bxh7+ Kxh7 22.Qh5+ Kg7 23.Qg5+! <if...Ng6 24.Bxf6+ Kg8 25.Qh6 and mate next move> 23.........Kh7 24.Qh4+ Kg8 25.Bxf6 Ng6 26.Qh6 And mate next move

Nov-27-13		Doniez: I found early the first move, I thought it was forced. White Queen is under attack, so White needs a check to gain a tempo. After 21.Bxh7,I was exploring ...Kh8, but it was not a good idea.

Nov-27-13		Patriot: 21...Kg7 is kind of critical, in my opinion, since the white queen is currently hanging. 22.Qg4+ Ng6 is key and it's still not that easy to see that white has an advantage. The biggest problem I had is there are so many threats to examine and nothing was obviously better. Therefore it's hard to figure out where to spend time. Some strong candidates are: Qg4+, Bxh7+, Qh5, Qe4, Qc2, d6, dxe6, Bxf6. But the threat of 21...Bxe2 helps rule out Bxf6, d6, and dxe6. 22.Qf3 in the game didn't register.

Nov-27-13		FSR: <21.Bxh7+!> and now: <21...Kxh7 22.Qh5+ Kg7> (22...Kg8 23.Bxf6 Ng6 24.Qh6 ) <23.Qg5+ Ng6> [23...Kh7 24.Bxf6 Nf5 (24...Rg8 25.Qh5#) 25.Qh5+ Nh6 26.Bg5 ] <24.Bxf6+ Kh7> (24...Kg8 25.Qh6) <25.Qh5+ Kg8 26.Qh6> and mates. <21...Kg7> (21...Kh8? 22.Bxf6+ Kxh7 23.Qh5+ Kg8 24.Qh8#) <22.Qf3> and I don't see a good defense against the dual threats of 23.Qxf6+ and 23.d6, e.g. <22...Nxd5 23.Rxd5 Bxd5 24.Qxf6+ Kxh7 25.Qg7#>.

Nov-27-13		FSR: Black was indeed a "Fried man" after 21.Bxh7+!

Nov-27-13		Steve.Patzer: After 21. Bxh7 Kg7 22. Qf3 doesn't e5 have some merit?

Nov-27-13		torro: Black was indeed a "Fried man" after 21.Bxh7+!)))))))))))))

Nov-27-13		Nick46: RIP (Fried a form of Friede = peace in German) after a two man showdown

Nov-27-13		FSR: <Steve.Patzer: After 21. Bxh7 Kg7 22. Qf3 doesn't e5 have some merit?> The problem with that is 23.d6 winning a piece, e.g. 23...Qc6 24.dxe7 and if 24...Qxf3, 25.exf8(Q)+.

Nov-27-13		agb2002: White has the bishop pair for a bishop, a knight and a pawn. Black threatens 21... Bxe2 and 21... Nxd5. Four white pieces are ready to attack the weak black castle. This suggests 21.Bxh7+ (21.Qh5 Nb6 22.Bxf6 Qf4 23.Bxg6 fxg6 with the double threat 24... Qxf6 and 24... gxh5; 21.Qg4+ Nb6 22.Bxf6 Qf4 simplifies the game, or 22.d6 Qd8 and White is still a pawn down): A) 21... Kxh7 22.Qh5+ A.1) 22... Kg7 23.Qg5+ Nb6 (23... Kh8 24.Bxf6+ Kh7 25.Qg7#; 23... Kh7 24.Bxf6 Nb6 (24... Rg8 25.Qh5#) 25.Qh5+ Kg8 26.Qh6 wins) 24.Bxf6+ and mate soon. A.2) 22... Kg8 23.Bxf6 Nb6 24.Qh6 and mate in two. B) 21... Kh8 22.Bxf6+ Kxh7 23.Qh5+ Kg8 24.Qh8#. C) 21... Kg7 22.Qg4+ Nb6 (22... Kh8 23.Bxf6+ Kxh7 24.Qg7#; 22... Kxh7 23.Qh5+ transposes to A; 22... Kh6 23.Qh4+ Kg7 24.Bxf6#) 23.Bxg6 fxg6 24.dxe6 looks good for White.

Nov-27-13		agb2002: According to Houdini 2.0 x64, after 21... Kg7, the text 22.Qf3 evaluates at about +11 and 22.Qg4+ only at +5.

Nov-27-13		morfishine: White must strike quickly since Black is ready to firm up his defenses with 21...f5 or 21...Qf4 or 21...Ng6 (which coordinates nicely with the Queen on f4) <21.Bxh7+ Kxh7> (If 21...Kg7, I thought White can simply force Black into the same mating pattern with 22.Qg4+ Kxh7 23.Qh5+ Kg7 24.Qg5+ Ng6 25.Bxf6+ Kh7 26.Qh5+ Kg8 27.Qh6 but it turns out to be a bit more complicate than this) <22.Qh5+ Kg8 23.Bxf6 Ng6 24.Qh6> and White wins *** PM: <21.Bxh7 Kg7 22.Qg4+ Kh6> Black is lost in any case <23.Bxf6> (or 23.Qh4+ Kg7 24.Qg5+ Kxh7 25.Qxf6 Rg8 26.Qxf7+ Kh6 27.Bc1+ Rg5 28.Qf6+ Kh7 29.Bxg5) and White wins since both 23...Nf5 and 23...Ng6 are met by 24.Qh3+ mating ***

Nov-27-13		pedro99: There's more than one way to batter a fish

Nov-27-13		zb2cr: Okay, 21. Bxh7+ is the first move. If Black declines with 21. ... Kg7, then the possibility of ... f5 is foreclosed, so 22. Qf3 works. Black can try to run with 22. ... Rh8, but that leads to disastrous loss of material after 23. Qxf6+, Kf8; 24. Qxh8+, Ng8; 25. Qxg8+, Ke7. Other lines s have been ably covered by previous posters.

Nov-27-13		Penguincw: 0/3 this week (thought of 21.Qh5 and 21.Bxf6). :(

Nov-27-13		LeifTerry: I don't think I've ever seen a sacrifice un-declined before.

Nov-27-13		kevin86: This was easy,white sacs the light bishop to force a mate with the dark bishop and queen-and when you can activate the pieces with a mate threat or check,it is even better,eg. 23...♔g8 24 ♗xf6 or 23...♔g7 24 ♕g5+!

Nov-27-13		FSR: <morfishine: ... <21.Bxh7 Kg7 22.Qg4+ Kh6> Black is lost in any case> 22...Ng6! 23.Bxg6 fxg6 is a much tougher defense.

Nov-27-13		Jimfromprovidence: I had a lot of trouble with this line: 21 Bxh7+ Kg7 22 Qf3 Nf5?! 23 Bxf5 exf5 click for larger view Now if 24 Qxf5, then 24...Rg8 provides an escape square. click for larger view After 25 Qxf6+ Kf8, I missed the winning 26 Ba3+! click for larger view
