| Dr. J: 36?
The initial move 36 Rxg7+ seems fairly obvious, since Black must soon give up his Queen, but Black's defense seems very poor. I do not see a clear win after 37...Qf7, although 38 Rxf7+ Kxf7 39 Qb3+ seems very promising. |

| Dr. J: Isn't this puzzle busted by 43.Nd5 Qd2 44.Qf5+ Kg7 45.Qxd7 Qxf2+ 46.Kh3 Qf3+ with a perpetual? |

Apr-27-16 Kharlov vs Tseshkovsky, 1996
| |
| Dr. J: I agree with the commenters above that 34.Ne4 fxe4 35.Qxe4+ Kh8 36.Rg6 is sufficient to be considered a solution to the puzzle, since White wins at least 2 Pawns and maintains the attack. But why did <patzer2>'s Fritz give an evaluation of +10.51, and why did Black resign? I ... |

Apr-19-16 M Tseitlin vs A Mikhalevski, 1996
| |
| Dr. J: 38.Bd6 Nc6 39.Qxc6(??) (my original choice) bxc6 40.Rxb8 Rd8 is not good. <al wazir>'s 38.Bd6 Nc6 39.Bxb8 Nxb8 40.Qg3 much better, but, instead of 39...Nxb8, Black can still struggle on after 39...Qg8, threatening 40...Rd8. So I suspect 39.Qg3 is somewhat more accurate. (Same ... |

Apr-11-16 D Coleman vs J Shepley, 2014
| |
| Dr. J: I believe the longest Black can hold out is 20.Qxf7+ Kh8 21.Re8 Qxe8 22.Rxe8 h6 23.Qxf8+ Kh7 24.Bg8+ Kg6 25.Qf7+ Kg5 26.Re5+ Bf5 27.Rxf5+ Kh4 28.Qh5#. Or does anyone see any improvements for either player? |

| Dr. J: <"28. Rd6 Bxd6; 29.exd6 Rc8; 30.d7 Rc7; 31.Qxc6 Rxc6; 32.Bxc6 and wins the BBP vs. Q ending, because Black cannot stop the eventual Queening of the d-pawn">. From the comments, this is what most of us (including me), and, I suppose, <cg> believed, but if ... |

Apr-06-16 G MacDonnell vs Gunsberg, 1883
| |
| Dr. J: Dr. J: While I believe it is very possible that the game continuation might stand up to computer analysis, on the basis of "the bind White gets is more than worth the sacrificed Pawn", or something like that, there is NO WAY that this is "Medium/Easy", and mis-labelling it as such ... |

Feb-28-16 Petursson vs Damljanovic, 1988
| |
| Dr. J: <BOSTER: After 54...Ke6 White can play 55. d8= N+. So, if 55...Kf5 56. Nd5+ Ke4 57. Nc3+ and after 57... Kd3 58.Nxb1, not Nxe2.> Oops. Of course you're right. <If 55...Ke7 56.Re8+ Kd6 57.Nf7+> and we have transposed back to the game continuation, where Black should play ... |

Feb-28-16 I Sokolov vs Polgar, 2003
| |
| Dr. J: <Patriot: 26.Bxg5 Bxg5 27.Qh5 and [I] thought 27...Ne4 28.Rg3 is quite strong.> Black can play 28...Nxg3 29.Qxg5+ Kf7 30.Qf6+ Ke8 31.Qe6+ Kd8 32.Qd6+ Ke8 and now both 33.Nc6 Ne2+ 34.Kh2 Rxc6 and 33.fxg3 Qb7 34.Nxf5 look unclear, though not unpleasant for White, who has at least ... |

Feb-23-16 Steinitz vs Von Bardeleben, 1895
| |
| Dr. J: <imbo2010> After 22...Kxe7 the critical line is 23 Re1+ Kd6 24 Qb4+ Kc7 25 Rc1+ Kb8 26 Qf4+ Rc7 27 Ne6 winning. There are a number of interesting-but-not-very-complicated side-variations that you should check out. |
