Feb-14-05  midknightblue: This was an enjoyable puzzle. Look for the forcing moves, and the solution follows quickly. How quickly? Who cares, I am not a lightning player anyway :)

  cu8sfan: Pry open the h-file - sac - sac - mate. Fischer said this about the Sicilian but it somehow suits the theme of today's puzzle.
Feb-14-05  your brilliance: Ah, the joys of delayed gratification! Lose the queen, hang the bishop, and then deliver mate!
Feb-14-05  rochade18: <BlazingArrow56> a double mate can only appear if there's a bishop or knight move (with check of course) which opens the line for a rook/queen. I've never seen such an end. Do you know any games with it?
Feb-14-05  white pawn: I got today's puzzle, but it took me a minute. I was thinking "restore equality" so I went 24...Bxe7, but I couldn't come up with anything after that. Then I thought, it doesn't matter who has what material, just who delivers mate. So I saw the obvious double discovered check, and then BAM. I think that's one of my problems. I look too much for keeping material even, or gaining material, that I forget about the prime objective.
Feb-14-05  RonB52734: <rochade18> there are other possibilities where one piece moves to both give check and reveal check. A pawn capture would open the pawn's former file just like the bishop move you mention. But the revealed check could also be on a diagonal, thus a knight, rook or queen move could both give check and reveal a bishop or queen check.
Feb-14-05  psmith: The solution to the puzzle was pretty obvious. So 22 ... Nd5 loses. Does Black have any defence? How about 22 ... Bd5? I can see that 23 Bc4 Bc4 24 Ne4 looks good for White, but what about, say, 23 Bc4 Bb7? I suspect White can win with an attack on the h-file but is there a forced win here?
Feb-14-05  crippledpawn: Saw it an instant!! Remember BxQ is a no no know matter how tasty it looks! Happy Valentine's Day to all you lovers out there!!
Feb-14-05  pastpawn: <psmith> I think that after 22 ... Bxd5, 23 Bxg4! is strong. 23 ... Be6 is practically forced ( 23 ... Nxg4 loses as in the game, and otherwise 24 Bxd7 will win). Then, after 24 Be2, say, I don't see a defense to g4, g5 by White.

  Annie K.: I don't recall seeing a double mate in the database, but here's one of mine: ;)

[Date "2004.08.06"]
[White "NN"]
[Black "Annie K."]
[Result "0-1"]

1. d4 d5 2. e3 Nf6 3. Be2 Nc6 4. Nc3 a6 5. Qd3 e5 6. dxe5 Nxe5 7. Qd4 Nc6 8. Qa4 Bd7 9. Qb3 Na5 10. Qxd5 Nxd5 11. Nxd5 Bb5 12. Bxb5+ axb5 13. Nc3 Bb4 14. Nf3 Bxc3+ 15. bxc3 o-o 16. o-o Ra6 17. Bb2 Nc4 18. Bc1 Rg6 19. e4 f5 20. exf5 Rxf5 21. Kh1 Qd5 22. Nh4 Rg4 23. Bg5 Rfxg5 24. Nf3 Rxg2 25. Rad1 Qxf3 26. Rd8+ Kf7 27. Rd7+ Kg6 28. Rd3 Rg1#

Feb-14-05  pastpawn: Actually, in the line above, 24 Nxe4 (instead of Be2) looks to me to be winning.

  notyetagm: Loose pieces and loose squares are the basis of combinations. Here it is the <looseness of the h8 square> that creates a <decoy> into a fatal <double check>, resulting in a <rook and bishop mate> down the <open h-file>: 23 Qh8+! Kxh8 24 Bf6++ Kg8 25 Rh8+.

The more I play chess, the more I appreciate the devastating power of discovered attack.

  kevin86: Another Reti-Tartakower style mate-but this has a few twists.

First,the black woman is tempting,we must avoid her and proceed to mate.

Second,before the discovered check there are three flight squares for the king. Two are taken away by the checking pieces-the one move left is to slither back to g8---and his doom!

  notyetagm: How can someone rated over 2300 even <contemplate> an atrocious move like 13 ... g5??? Did she forget that W had castled queenside? I am rated only in the 1300's but would be ashamed to play a game like this.
Feb-14-05  euripides: <notyet> 13...g5 is not quite as clearly wrong as it might seem. White is likely to be able to open the king's side anyway by g4-g5, and the pin on the knight is problematic. One later possibility that might keep the king's side under control was 16...g4.

  notyetagm: <euripides: <notyet> 13...g5 is not quite as clearly wrong as it might seem.>

Perhaps, but why not just play ... Nbd7 and then move the queen out of the pin at some earlier point, instead of playing the <profoundly weakening> 11 ... h6 and 13 ... g5? I just do not understand Black's thinking at all. If she had already played ... Nc6 then her actions would be understandable but since she hadn't, playing 11 ...h6 and 13 ... g5 when she could have played ... Nbd7 looks insane to me.

Feb-14-05  euripides: <notyet> 11...Nbd7 may be an improvement. Black may have been worried about tricks on the d3-h7 diagonal, but an immediate 12 Bd3 could be met by e4. However, after 12 f3 Black still has problems, partly because there's no very good square for the queen to go to.
Feb-14-05  Hektor: Although black's position is beginning to look a little grim by move 22, 22... Nxd5? looks like a horrible oversite on black's part especially by a 2300 player.
Feb-14-05  Knight13: I saw Qh8+ but I wasn't thinking about Bf6+. Good puzzle.
Feb-14-05  poktirity: Saw it instantly because I tried similiar combos today in some blitz games, though mine always failed.
Feb-14-05  mahmoudkubba: It just took me very little to solve this one.. not a very difficult one at all..
Feb-14-05  DanielBryant: I felt good about this one, then I checked the calendar...
Feb-14-05  Backward Development: pretty easy, anyone who's looked at the mating patterns in 'The Art of Attack' should recognize this theme. Maybe a more complex version of it is shown here... G Abramovic vs Botvinnik, 1924
Apr-29-06  CapablancaFan: Haha. Ms.Caoili thought she was exchanging queens towards the end winning a pawn in the process, but Ms.Peng had something else in mind!
Jun-14-06  alexapple: Great win for GM Peng!
