| Jan-26-11 | | plateos: 26. ... Dxh2+
27. Kxh2 Th6+
28. Kg3 Lh4+ (Lh3 Txh3#)
29. Kf4 g5# or Kh2 Lxf2 followed my mate. |
|
| Jan-26-11 | | gmalino: This puzzle seems tp be a little bit too easy for wednesdays.
It smells like
26.......Qxh2+
27.Kxh2 Rh6+
28.Kg3 Bh4+
29.Kf4 Rf6#
This line is forced, if white plays
29.Kh2 Bxf2#
No other variations possible, no pieces to throw into blacks legs. A good example of really good coordinated pieces. |
|
| Jan-26-11 | | gmalino: <plateos> You should use the english transcription for the pieces.
:-) |
|
| Jan-26-11 | | gmalino: <phony Odd how everyone so far, in the 29.Kf4 variation, is finding 29...g5# instead of 29...Rf6#.> I didn't even think of g5#, as I saw Rf6 mates I sat my brain into stand-by-mode. |

<26....?>
Material: White up, ♖ vs ♗+♙
Candidates: fxg2†, <[Qxh2†]> -ML-
Although I'd seriously doubt whether fxg2† would not win for Black, destruction is key here for mate in four. <26....Qxh2† 27.Kxh2 Rh6† 28.Kg3 (Bh3 Rxh3‡ 0-1) Bh4† 29.Kf4 (Kh2 Bxf2† 30.Bh3 Rxh3‡ 0-1) g5‡ 0-1> a coorperation of pieces ensnaring a King, so common, yet I never get it in my advantage. |
|
| Jan-26-11 | | Nullifidian: Saw this within half a minute.
Like many people, I started considering ♙fxg2, but then I realized 26... ♕xh2+! was the key move for an inescapable mate in 5. Play continues: 27. ♔xh2▢ ♖h6+ 28. ♔g3 (♗h3 ♖xh3#) ♗h4+ 29. ♔h2 (♔f4 ♖f6#) ♗xf2+ 30. ♗h3▢ ♖xh3# |
|
| Jan-26-11 | | gofer: Forced mate in 5 (26 ... Qxh2+ 27 Kxh2+ Rh3+ 28 Kg3 Bh4+ (Bh3 Rxh3#) 29 Kh2 Bxf2+ (Kf4 Rf6#) 30 Bh3 Rxh3#) The only things left to discuss is "Was there something white could have done a couple of moves earlier to avoid this?" and "when did he resign?". |
|
| Jan-26-11 | | Oxnard: White's problem is that all his pieces are useless.
Qxh2+ Kxh2 Rh6+ then either
Bh3 Rxh3#
or
Kg3 Bh4+ and either Kf4 Rf6# or Kh2 Bxf2+ Bh3 Rxh3# |

 | | OhioChessFan: As a puzzle position, this was about Monday level. If I didn't have the warning that something significant was about to happen, it would have been much harder. |
|
| Jan-26-11 | | Ratt Boy: Nobody has commented on Black's brilliant 23...♖xd2!, which set up the puzzle, which I agree is relatively easy for a Wednesday. Black to move at Move 23 might be a good Friday or Saturday puzzle. White could have avoided mate with 26.♗xf3, but he would've been down a piece, for e.g. after 26...♗xf3+ 27.♘xf3, ♘xf3 28.♖g2, ♘xe1. Very pleasing combo! |
|
| Jan-26-11 | | msmith5: I saw it up to Bh4+ but didn't see the last two moves to finish white off so I thought it was a spoiler. |
|
| Jan-26-11 | | kurtrichards: 26. ... Qxh2+ winning. |
|
| Jan-26-11 | | agb2002: Black has the bishop pair and a pawn for a rook and a bishop. The convergence of the rook on g1 and the white queen on g7 might represent a problem in the case of non forcing maneuvers. Therefore, 26... Qxh2+ 27.Kxh2 Rh6+ 28.Kg3 (28.Bh3 Rxh3#) Bh4+ 29.Kh2 (29.Kf4 Rf6# or 29... g5#) Bxf2+ 30.Bh3 Rxh3#. |
|
| Jan-26-11 | | zb2cr: So simple even my simple mind saw all the forced variations. I particularly enjoyed the fact that if 29. Kf4, Black has a choice of two mates with 29. ... Rf6# or 29. ... g5#. |

| Jan-26-11 | | Hongkonger: <Once>
Thank you for your brilliant artwork. |
|
| Jan-26-11 | | David2009: S Mulligan vs D Foord, 2006 Black has sacrificed the exchange for a Pawn and a forced mate:
26...Qxh2+ 27 Kxh2 Rh6+ 28 Kg3 (if 28 Bh3 Rxh3#) Bh4+ 29 Kh2 (or 29 Kf4 Rf3#) Bxf2+ 30 Bh3 Rxh3#

Got it. <plateos: (commenting on A Neumann vs Przepiorka, 1904) I was just wondering whether it is possible to post before seeing the game?> Try writing your solution out in

| Jan-26-11 | | CHESSTTCAMPS: In this middlegame attacking position, black has a big space advantage and a powerful attack for the exchange. Black can certainly grab the lead in material by playing 26... fxg2(?), but the high activity level of the black pieces and the fact that white's majors on the 3rd rank are screened off from the defense of the king suggests that a quick kill is available: 26... Qxh2+!
A familiar sacrifice in this type of position. White can't prevent mate. 27.Kxh2 Rh6+ 28.Kg3 (Bh3 Rxh3#) Bh4+ 29.Kh2 (Kf4 g5#) Bxf2+ 30.Bh3 Rxh3# When the forcing moves of the combination are all checks, the calculation is easy. |
|
| Jan-26-11 | | patzer2: For today's Tuesday puzzle solution, 26...Qxh2+! forces a quick mating attack. White's decisive error was 19. b4?, when Black wins with either 19...Qh5! or 19...axb5 20. Bxa5 Qh5  . Instead, 19. Rae1 Nc5 20. Qe2 Bf6  leaves Black in the game with reasonable counter chances. A more worth analyzing is the Rook lift 21...Rf6!, which is the only clearly winning continuation. |
|
| Jan-26-11 | | azax: <phony> Odd how everyone so far, in the 29.Kf4 variation, is finding 29...g5# instead of 29...Rf6#. At least for me, my eye has been trained to look for "Bughouse mates" first -- contact mates as opposed to ones where my opponent could drop a piece and stall for a move. |
|
| Jan-26-11 | | 1.e4effort: This looks like an onslaught by Black to me - B pieces are all drooling, ready for the attack. White has got nothing going on, other than digging a bunch of shallow graves. I feel like a waiter at the fancy H-file restaurant - first, "let's start with
26...Qxh2+ and after
27. Kxh2...we'll have a nice dish of Rh6+
After 28. Kg3 we'll have a fine souffle of Bh4+. You've had enough?? and no dessert?? I assume you'll be paying with a check?!?!" |
|
| Jan-26-11 | | JG27Pyth: Good puzzle, considering the dominating position Black acheived, and the sound queen sac, it seems clear: Foord forethought! |
|
| Jan-26-11 | | estrick: <azax: my eye has been trained to look for "Bughouse mates" first> I blame Bughouse for turning me into a 'sac first, ask questions later' player. |
|
| Jan-26-11 | | kevin86: The final position is amusing,white can choose the method of mate,but either way,the rook does its maximum: 29 ♔h2 ♗xf2# discovered mate or
29 ♔f4 ♖f6# direct mate. |
|
| Jan-26-11 | | galdur: Didn´t spot 29...g5 mate, but 29...Rf6 achieves the same. |
