 | | al wazir: I naturally figured that 13. Nxf7 was the first move in the combination; f7 is almost always a weakness for the uncastled black ♔, as h7 is for one that has castled K-side. But I couldn't see a win after 13...Bxh2+ 14. Kxh2 Qc7+ 15. g3 Qxf7. I still can't. |

White to play 13.?
White is 3 pawns down.
13.Qe2 with the intention of later Nc6+ and picking up the Black Queen. 13............Bxe5
14.Qxe5+ Kd7
15.Rxb2 f6
16.Bf5+ Kc6
17.Rc1+ Qc5 (to prevent mate)
18.Rxc5+ Kxc5
19.Qc3+ Kd6
20.Bf4+ Ke7
21.Bxc8 Nc6
White is stronger and should win
I'll see how the game continued |

| | patzer2: After a lapse of eight years before seeing the position again, I recalled 13. Nxf7!! Kxf7 14. Qh5+, but was stumped in finding a continuation after the expected 14...Kf8 15. Rfe1 Bd7 (position below).
click for larger viewHere, Fritz 12 indicates the strong 16. Re3! is the only decisive move. It's easy to see 16. Re3! wins after the computer recommends the move. However, I missed visualizing this strong Rook lift four moves ahead in calculating 13. Nxf7!! |

| Aug-24-13 | | JimmyRockHound: How does white continue if black plays: 14. ...Kf8 ? |

| Aug-24-13 | | kabirbel: N×f7 is a good way to expose the king, activate the queen and get a advantageous position |

| Aug-24-13 | | Dr. Funkenstein: White to play…. Keres is down 3 pawns so clearly he has a tactical shot of some sort planned that the rest of us need to find… 13. Nxf7 threatening the d6 bishop and h8 rook
13. …Kxf7 14. Qh5+
…g6 15. Bxg6+ hxg6 16. Qxh8 looks good with open lines to attack …Kf8 16. Rfe1 Bd7 17. Re3 threatening Rf3+
…Kg8 16. Rfe1 g6 (Bd7 17. Re8+ Bxe8 18. Qxe8+ Bf8 19. Qe6#) 17. Bxg6 13. …Qc7 14. Nxh8 doesn’t look good for black even with the knight in the corner temporarily -- Didn’t fully analyze 13. …Bxh2+ 14. Kxh2 Qc7+ and I doubt I would have found 15. Ne5! In this line |

 | | kevin86: Eight of black's first eleven moves were wuth pawns. He had triplets on move 8-a great receipe for defeat. |
|
| Aug-24-13 | | gofer: I looked at Nxf7 for a long time. Black can reply with Bxh2+, O-O and Kxf7.
After I had managed to avoid the complications of Bxh2+ with Kh1 everything
became a lot clearer. Black has to accept the knight sacrifice! <13 Nxf7 ...>
13 ... O-O
14 Nxd6
13 ... Bxh2+
14 Kh1 Kxf7 ( O-0 Qh5 )
15 Qh5+ g6 (Kf8 Rfe1 )
16 Qf3+ Kg8 (Ke8 Qf6 or Ke6/Kg7 Qf6+ or Bf4 Bxf4 ) 17 Rfe1 Bd7
18 Be7
<13 ... Kxf7>
<14 Qh5+ ...>
14 ... Ke6+ 15 Bf5+
14 ... Kf8 15 Rfe1 Bd7 16 Qf3+ Kg8 17 Be7
14 ... Kg8 15 Qe8+ Bf8 16 Qxc8
<14 ... g6>
<15 Bxg6+ hxg6>
<16 Qxh8 ...>
At which point, white has ripped open black's defenses. A single solitary pawn
stands up in front of the king and defending that AND the two loose bishops is
a tall order...

Yep! |

 | | Jimfromprovidence: 17 Re1 is such a great move.
click for larger viewThe threat is 18 Qh7+ Kf8 19 Bh6#.
The rook is untouchable because if 17...Qxe1+ 18 Rxe1 b1Q, it's still mate in two as shown above. <Notyetagm> had pointed this out back in December 2004. It looks like in the end one way white can win is to set up a nice discovered check winning the queen (like below) after a series of checking moves.

 | | agb2002: White is three pawns down.
Black's threat 13... Bxe5 is not real because of 14.Re1 Nc6 (14... O-O 15.Rxe5 f6 16.Qh5 with attack) 15.f4 recovering the piece and 13... f6 loses to 14.Qh5+. The king in the center invites to play 13.Nxf7:
A) 13... Kxf7 14.Qh5+
A.1) 14... Ke6 15.Bf5+ Ke5 (15... Kxf5 16.Bd2(8)+ and 17.Bxa5 + - [Q vs B+N+2P]) 16.Rfe1+ Kd4 (16... Qxe1+ 17.Rxe1+ Kd4 (17... Kxf5 18.g4#) 18.Qg4+ Kc5 19.Bxc8, etc.) 17.Be3+ A.1.a) 17... Kc4 18.Qe2+ Kb4 (18... Kc3 19.Qxb2+ Kc4 29.Qb3#) 18.Qxb2+ and mate next. A.1.b) 17... Kc3 18.Bd2+ Kxd2 (18... Kc4 19.Bxa5 g6 20.Qe2+, etc.) 19.Qe2+ Kc3 20.Qxb2+ Kc4 21.Rec1+ Qc3 22.Qxc3#. A.2) 14... Kf8 15.Rfe1 Bd7 (15... Qa4 16.Qf3+ Kg8 17.Qxd5+ Kf8 18.Qxd6+, etc.) 16.Qf3+ (16.Bxh7 Qc3) 16... Kg8 17.Be7 Nc6 (17... Bxe7 18.Rxe7 + -) 18.Bxd6 recovers the piece and keeps the attack. A.3) 14... Kg8 15.Rfe1 Bd7 16.Re8+ Bxe8 17.Qxe8+ Bf8 18.Qe6#. A.4) 14... g6 15.Bxg6+ hxg6 (15... Ke6 16.Bf5+ as in A.1; 15... Kg7 16.Bh6+ Kf6 (16... Kg8 17.Bf7#) 17.Qg5+ Ke6 18.Bf5+ Kf7 (18... Ke5 19.Bg7#) 19.Qg7+ Ke8 20.Rfe1+ and mate soon; 15... Kf8 16.Rfe1 Bd7 17.Be8 seems to win; 15... Kg8 16.Rfe1 is similar to the previous subline) 16.Qxh8 recovers material and keeps the attack. A.4.a) 16... Bf5 17.Qf6+ Kg8 (17... Ke7 18.Qxd6 Nc6 19.Rxb2 + - [R vs N]) 18.Qxd6 Bxb1 19.Qe6+ Kg7 20.Qe7+ Kg8 21.Bf6 and mate soon. A.4.b) 16... Bb4 17.Qf6+ Ke8 18.Qxg6+ Kd7 19.Qg7+ Kc6 20.Qxb2 and the material is more or less balanced but White keeps the attack. B) 13... Bxh2+ 14.Kxh2 Kxh7 15.Qh5+ looks favorable for White because the square e7 is now available for a rook or bishop. |
