|Oct-20-15|| ||patzer2: Forgot I'd seen this position 9 years ago, but still managed to find today's Tuesday solution 29. Rxh7+! when it's mate-in-six after 29...Kxh7 30. Rh1+ Nh6 (30... Kg8 31. Rh8+ Nxh8 32. gxh8=Q+ Kf7 33. Qg7#) 31. Rxh6+ Kg8 32. Rh8+ Kf7 33. Nh6+ Kg6 34. Qf5#.|
As for Black improvement's, <Acirce>'s 2006 post with John Watson's suggestion of 12...a6 as in Chandler vs Ulf Andersson, 1980 looks OK.
However, I'm not convinced <12...Bf5> is "so bad" as Watson claims. After <12...Bf5 13.0-0 Nbd7 14. g4>, Deep Fritz 14 indicates Black is OK after 14...Bg6 15. Nf4 Ne5 16. Nxg6 Nxg6 17. Na4 Rc8 18. b4 Bb6 19. Nxb6 Qxb6 20. Re1 h6 21. Be3 Qb5 22. Qd4 a6 23. a4 Qc4 24. Qxc4 Rxc4 = (0.00 @ 24 depth).
P.S.: Do we need to see mate-in-six to solve Tuesday puzzles? If so, the bar has been raised.
|Oct-20-15|| ||saturn2: nalinw: 31 BxRe7, I think white is still considerably better|
|Oct-20-15|| ||roentgenium: My attempt was 29. Rxh7, threatening 30. Rh8+ Nxh8 31.gxh8Q+ Kf7 32. Qg7#. |
If Black tries 29...Ng5 or 29...Ne5, then 30. Rh8+ Kf7 31. BxN and the Bishop cannot be recaptured due to the threat of the family fork 32. Nxd6+, and in any case, the upcoming Qh5 by White should be sufficient. Any other Black Knight move is met with the same family-fork idea, just earlier.
Finally, if Black accepts the Rook with 29...Kxh7, then 30.Qh5+ Kg8 31.Qh8+ Nxh8 32.gxh8Q+ Kf7 33.Qg7#. In this line, if Black tries 30...Nh6, then 31. Qxh6+ Kg8 32. Qh8+ Kf7 33. Nxd6+ Kg6 (33...Kxf6 g8Q+ discovered check) 34. Nxb4 Rxh8 35.gxh8Q Rxh8 36. Bxh8 leaves White up at least a Rook ahead.
|Oct-20-15|| ||goodevans: The majority seem to go with 29.Rxh7 Kxh7 30.Rh1+ but like <FSR> and <roentgenium> I went with 29.Rxh7 Kxh7 30.Qh5+ which is simpler (fewer options to evaluate) and one move quicker.|
|Oct-20-15|| ||offramp: Csom be Nightmare!|
|Oct-20-15|| ||dfcx: A couple of good choices for white, Rxh7 and Qh5. Qh5 is refuted by h6. Let's try |
A. 29...Kxh7 30.Rh1+
A1. 30...Kg8 31.Rh8+ Nxh8 32.gxh8=Q+ Kf7 33.Qg7#
A2. 30...Nh6 31.Rxh6+ Kg8 32.Rh8+ Kf7 33.Nh6+ Kg6 34.Qf5#
A3. 30...Kg6 31.g8=Q+ Rxg8 32.Ne7#
If black refuses the rook without moving the knight,
B. 30...??? 31.Rh8+ Nxh8 32.gxh8=Q+ Kf7 33.Qg7#
|Oct-20-15|| ||starry2013: At first I was looking at the knight checks as that is forcing. Didn't see anything.|
Then moved onto Rxh7 which isn't a check but as a sacrifice it forces all kinds of havoc. One thing it gets is a nice knight fork. And that knight position covers f7 for the checkmate. I did consider bringing the queen in rather than the second rook at first, but keeping the queen back stops any counter checks.
So this was my best
checkmate next move (Rh8) and the computer just gives up pieces to delay
|Oct-20-15|| ||CHESSTTCAMPS: White has the material advantage of a pawn that is a protected monster on g7. Combined with the advantage of the semi-open h-file, white can force victory quickly:|
29.Rxh7! threatens Rh8+ forcing mate. 27.Qh5? Qxd5+ is non-forcing and unnecessarily allows counter-play.
A. 29... Kxh7 30.Qh5+ Kg8 31.Qh8+ Nxh8 32.gxh8=Q+ Kf7 33.Qg7#
A.1 30... Nh6 31.g8=Q+! Kxg8 (Rxg8 32.Qxh6#) 32.Qg6+ Kf8 33.Qg7#
B. 30... other 31.Rh8+ Nxh8 32.gxh8=Q+ Kf7 33.Qg7#
|Oct-20-15|| ||CHESSTTCAMPS: whoops - a bad hole in A.1. Restart week....|
|Oct-20-15|| ||kevin86: White will mate after a sac (or two) at h8 via the knight at h6. Brilliant Kasparov!|

Game Collection: LINE-OPENING SACRIFICES: TARGET -> LOOSE SQUARE 29 Rh1xh7! 1-0 blasts open the h-file to get at the h8-square next to the Black g8-king
|Oct-20-15|| ||psmith: I went with Qh5+ rather than Rh1+. But contrary to what <goodevans> says this is slower. Rh1+ is mate in 5. Qh5+ is mate in 10 against best defense (and to get that mate you have to follow Nh6 with Nxh6 rather than Qxh6+ as I had planned and <FSR> analyzed).|
|Oct-20-15|| ||saturn2: <dfcx 29 Qh5 is refuted by h6> 29...Qxd5+ should be even worse for white|
|Oct-20-15|| ||gawain: I thought about 29 Rxh7 but I was preoccupied with the fact that 29 Nh6+ is almost mate. Almost. |
Distracted by the black knight I decided to try 29 Qh5 instead, thinking that Black had nothing better than the hopeless 29...Nh6. Wrong! Later, after finding out that 29 Rxh7 was the winning move, I noticed that 29 ....h6 refutes Qh5. Careless of me.

|Oct-20-15|| ||Check It Out: I saw 29.Rxh7 but didn't do so well following it up. Seems like a difficult Tuesday, following a difficult Monday. By the time we get to Sunday we'll need Carlsen's help.|
|Oct-20-15|| ||Bubo bubo: 29.Rxh7! threatens mate in three starting with Rh8+. Black has no sufficient defense:|
A) 29...Kxh7 30.Qh5+ Nh6 (or 30...Kg8 31.Qh8+ Nxh8 32.gxh8Q+ Kf7 33.Qg7#) 31.Qxh6+ Kg8 32.Qh8+ Kf7 33.Nxd6+ and Black loses the queen or his rooks: 33...Kxf6 34.Qh6+ and 35.Nxb5 resp. 33...Kg6 34.Nxb5 Rxh8 35.gxh8Q Rxh8 36.Bxh8
B) Moving the knight leads to mate: 29...Ng5 30.Rh8+ Kf7 31.Nh6+ Kg6 32.Qf5+ Kh5 33.Rh1#
C) Moving the Re8 down the e-file avoids immediate checkmate, but loses house and home after 30.Rh8+ Nxh8 31.gxh8Q+
|Oct-20-15|| ||The Kings Domain: Nice game by the young Kasparov. Although he was no prodigy the sound attacking style he became known for was already in place by then.|
|Oct-20-15|| ||Ackj: The home page says "29?" but shows the position at move 28. I'll take at least a little credit for finding 28.Nf5 threatening mate or royal fork.|
|Oct-20-15|| ||jdc2: The position on the front page was after move 27, not 28. Still got 28. Nf5 Nf7 correct, after that I didn't see clearly.|
|May-29-16|| ||Chessman1504: The Rxh7 sacrifice bears a slight resemblance to the winning tactic Nakamura missed against Carlsen in Zurich 2014.|
|May-29-16|| ||yiotta: Basically, this was Garry giving odds of the queen's rook, see final position. (OK, just felt like kibitzing :).)|
|May-29-16|| ||RookFile: Black played 10...Bc5. What exactly did that accomplish for him?
The question here is whether white is going to attack, or black. You need to establish what the roles are going to be. If you're supposed to play defense, then play defense.|
In this game black thinks he's going to attack. He's going to whip up an attack on f2. Well, it didn't exactly
work out, did it. The bishop ends up somewhere on the queenside, doing nothing,
while black's kingside burns down. Ugly or not, 10....d6 followed by developing
the queenside pieces would have been a lot better for black than the game.
|Feb-01-17|| ||Albion 1959: So where was the extra queen? There was actual promotion in the game. Yes there were some lines when black resigned that showed the promotion of the pawn on g7, but to class this in the multiple queens category - NO !|
