|May-12-05|| ||patzer2: <worktobedestroyed> If 46...Qxd7, then 47. Qg3+! Kh1 48. Rxf8# follows.|
|May-12-05|| ||aginis: <Hesam7> right you are 56 e7 Qb8+ 57 g3+ is faster|
|May-12-05|| ||patzer2: It's hard to classify 45. f5!! in a particular tactic category. In one sense it's a deflection. In another sense it supports the passed pawn and it also creates a number of mating possibilities. However, since Black is castled and 44...Qc6? fatally weakens that position, I'm calling it an attack on the weakened castled position.|
|May-12-05|| ||delterp: My question is why not 29. ♖bxg6+?
White is going to exchange rooks anyway, so why not make a desparado out of the piece and gain a pawn?
|May-12-05|| ||Snow Man: Took me about 6 minutes...|
|May-12-05|| ||YouRang: I missed it. I looked at f5, but I didn't see how it forced anything. Interesting puzzle.|
|May-12-05|| ||kevin86: Harder than it looks! The key move is not too hard,but a lot of loose ends need to be dealt with the position. |
The pawns go marching along!!
|May-12-05|| ||aginis: 29.Rbxg6 hxg6 30.Qxe4 Qe1+! 31.Kh2 Re8
32.Rxg6+ fxg6+ 33.Qxg6+ =
while 29.Qxe5 leaves white up a pawn
|May-12-05|| ||Cee75: <boomie>
45... g5 46. f6 h6 Now why not
47. Rxf7 ?? will finish it much faster
|May-12-05|| ||Stonewaller2: <I'm calling it an attack on the weakened castled position.> I'd be inclined to agree. 45. f4 threatens to open the g-file for the ♕, giving 46. ♖e8 a sharp point it didn't have before, as you note: 46. ... ♕c6 47. ♕g3+ ♔h8? 48. ♖xf8# or 47. ... ♕g6 48. ♖xf8+ and the ♙ promotes.|
|May-12-05|| ||JohnBoy: After 45.f5 f6, white wins perhaps more quickly than <Hesam's 46 Qg3 g5 47 h4! h5 48 hxg5 h4 49 Rg7! Kh8 [49 ...Kxg7 50 gxf6 Kxf6 51 Qg6+] 50 Qh4 Kxg7 51 Qh6 Kg8 52 Qxf8+ Kxf8 53 d8Q+ Kf7 [ 53 ... Kg7 54 Ke7] 54 g6 Kg7 55 Qe7 Kh6 56 Qh7 Kg5 57 g7>. White can try 46.Qe6+ Qxe6 47.fe6, when black can do nothing effective to stop Re8. Suppose black plays 47...a2. White wins with 48.Re8 a1Q 49.Rxf8+ Kxf8 50.d8Q+ Kg7 51.Qc7+ Kh6 52.e7, and the e pawn will promote.|
Not that Hesam's line is wrong, it's just that w/o board I see maybe 5 moves ahead, rather than 10.
|May-12-05|| ||xxdsdxx: After searching through all of the Rook Queen possibilities, promoting the stranded pawn to no avail, who would of thought to start with something so esoteric as marching another pawn down the board! Good puzzle...|
|May-12-05|| ||gerpm: I think Qg3 wins.|
|May-12-05|| ||Hektor: I figured out the initial move (45.f5) but completely overlooked the complexities associated if black declines the sacrifice with 45...a2, or g5 (so in effect I missed this one). Kudos to you all for the great discussions associated with these and other lines. This is one of those puzzles that is much more complex than it initially seems.|
|May-12-05|| ||isaac.gl: why not just
|May-12-05|| ||paulalbert: The K can take on f7 and then white has nothing.|
|May-12-05|| ||Richard Taylor: I looked at f5 but couldn't see anything - Torre played the famous combo with he back rank mate theme did he not? I would porbably have gone for f5 but I thought there was no way through after a2 -oh well see how I go next problem...|
|May-12-05|| ||RookFile: E Z Adams vs Carlos Torre, 1920|
|May-13-05|| ||JohnBoy: What is your point here <RookFile>? You lead us to a famous game to what end? How does it follow naturally from the discussion here?|
|May-13-05|| ||Boomie: <Hesam7 - In your line White wins much faster with 49 gxh6 instead of 49 Qg3> |
Dang. I was really fond of that line. Thanks for the heads up.
|May-13-05|| ||Boomie: <Cee75> I fell for ♖xf7 at first, forgetting that the king is a piece, too.|
