|Aug-10-11|| ||Dr. J: Yes, that's how I saw it. About a Wednesday-level puzzle, I think.|
|Aug-10-11|| ||swr: Got it in a split second, nice|
|Aug-10-11|| ||agb2002: White has a knight or a bishop.
Black threatens perpetual with 34... Qh3+ (35.Ke2 Rb2+ and 36... Bxa7).
White can avoid 34... Qh3+ and create a decisive threat against g7 with 34.Ng5, blocking the black queen:
A) 34... fxg5 35.Rxg7+ Kh8 36.Rxh7+ Kg8 37.Qg7#.
B) 34... Qh4(5) 35.Rxg7+ Kh8 36.Rxh7+ Qxh7 37.Qxh7#.
C) 34... Rb7 35.Qxb7, etc.
D) 34... Rfb(c)8 35.Rxg7+ and mate in two at most.
E) 34... Qe2+ 35.Kg2 (35.Kxe2 Rb2+ 36.Kf1 Bxa7 (36... Rxf2+ 37.Kg1 Bxa7 38.Rxa7 + -) 37.Rxa7 fxg5 38.f5 (38.fxg5 R8xf2+) 38... exf5 39.e5 Rf7; 35.Rxe2 Rb1+ 36.Re1 Rxe1+ 37.Kxe1 Bxa7 38.Rxa7 fxg5, etc.) 35... Qg4+ 36.Kh1 + -.
F) 34... Rf7 35.Rxf7 Bf8 36.Rxf8+ Kxf8 37.Qxb6 fxg5 38.Qd8+ Kf7 39.Qxg5 + -.
|Aug-10-11|| ||Patriot: I looked at this in 'blitz mode' and chose 34.Ng5 in under a minute or so.|
|Aug-10-11|| ||sevenseaman: <Dr. J> Black wins with Rb5. White can see no profit in sacking his R on g7, so he has to save his Q. The Black B covers a3 and Q cannot support the threatened f3 N. At best it can choose a5 attacking the b5 R or it retires to a2 aiming for a spite check at e6 . The N falls. Whatever White does the Black Q will have time to check from h1 or f2.|
<1...Rb5 2. Qa2 Qxf3 3.~ Qf2 (or Qh1)#>
|Aug-10-11|| ||Fuegoverde: 34 Ng5 , and black cannot defend g7|
|Aug-10-11|| ||dadoktor: Ng5 is easy move more like tuesday i think|
|Aug-10-11|| ||number 23 NBer: 34 ♘g5 and I can't see anything for Black to do. Nice interference theme.|
|Aug-10-11|| ||kevin86: The knight to g5 move is simple and instructive. Checkmate is threatened along the seventh row and black has no answer.|
|Aug-10-11|| ||LIFE Master AJ: 34.Ng5! covers g7, threatens a nice mate in three. (I see no adequate defense.)|
|Aug-10-11|| ||NM JRousselle: It's a shame that Black threw away a slightly better game. 33... Rd6 is a better move that allows Black to trade rooks & then play Qg4. Black had the right idea, but...|
|Aug-10-11|| ||David2009: Speelman vs Short, 1980 White 34?|
34.Ng5 GOOT! wins material Best for Black seems to be 34...Qe2+! UNGOOT! 35.Rxe2 Rb1+ 36.Kg2 Bxa7 37.Nxe6 Ra8 38.Rxg7+ and White is two Pawns up.
Time to check:
Here's the puzzle position:

The EGT improves on my 34...Qe2+ defence meeting 34.Ng5 with 34...Kh8 35.Rxg7 Qe2+ 36.Rxe2 Rb1+ 37.Kg2 Bxa7 38.Nxe6 Rg8 39.Rxg8+ Kxg8

and I am not sure whether to continue 40.e5 presumably met by 40...Kf7 (not 40...f5 41.Ng5 ) or with 40.f5 . No time for more now,
back later. Enjoy playing this out to a win unaided by silicon!
I see that other kibizers have already suggested the 34...Qe2+ defence.
<DrMAL>: thanks for your comment (Tal vs Hjartarson, 1987, 7 August). The reason I like Crafty EGT is that it is available to everyone as a standardised and respected opponent. I agree that it is strong
but by no means perfect and as <CHESSTTCAMPS> discovered its playing strength (the defences it finds) can change from day to day. This doesn't matter. <Just a suggestion, cheers.>. Thanks for making it -have you considered opening your own forum (a good place for responding)?

33...Rd6 34. Rxg7+ Kh8▢ 35. Rh7+ Kg8▢ 36. Qg7#
|Aug-10-11|| ||abuzic: <Dr. J:...<BLACK> TO PLAY AND WIN>
(same position after balck's move 33)
Black wins the exchange after: 1...Rb5 2.Qc7 Bb6 3.Qc3 Ba5 4.Qd3 Qh3+ 5.Kg1 Bxe1 6.Nxe1 Qxd3 7.Nxd3.
|Aug-10-11|| ||chessgames.com: Just for the record, the Chessgames staff had no idea about the shocking 34...Qe2+ (!) resource. Apparently it doesn't change the outcome, but it's certainly a fun continuation to examine. Thanks, brilliantly spotted.|
|Aug-10-11|| ||psmith: <sevenseaman> It's 33...Rd6 that was suggested, with the Queen still on g6. Not 34...Rd6 with the Queen on g4 and Knight on g5. So 33... Rd6 34. Rxg7+??? Qxg7 .|
|Aug-10-11|| ||beenthere240: <David2009>
41. f5 has the advantage of anchoring the knight with pawns on light squares and also frees the f4 square in case the knight needs to be redeployed. In the current position, ,,,Kf7 would be uncomfortable for the knight.
|Aug-10-11|| ||Creg: 34.Ng5 looks like the right move. It blocks the black queen from protecting g7 and threatens 35.Rxg7+ which in turn will lead to mate.|
|Aug-10-11|| ||estrick: <David2009: Speelman vs Short, 1980 White 34?Crafty End Game Trainer link: http://www.chessvideos.tv/endgame-t... The EGT improves on my 34...Qe2+ defence meeting 34.Ng5 with 34...Kh8 35.Rxg7 Qe2+ 36.Rxe2 Rb1+ 37.Kg2 Bxa7 38.Nxe6 Rg8 39.Rxg8+ Kxg8 to reach . . .> |
instead of <38. Nxe6>,
I played 38. Rxh7+ followed by 39. Rxa7, and after 40 . . . fxg5, 41. fxg5 and White is up with four connected pawns vs one, which even I couldn't botch, even on the first try.
|Aug-10-11|| ||estrick: <agb2002: E) 34... Qe2+ 35.Kg2 . . . Qg4+ 36.Kh1 + -. >|
Doesn't Black just play 35 ...Qxf2+ leading to a quick win for the second player?
|Aug-10-11|| ||agb2002: <estrick: <agb2002: E) 34... Qe2+ 35.Kg2 . . . Qg4+ 36.Kh1 + -. >|

You're right thank you! I can't explain this blunder, since I saw the possibility of taking the f2 pawn with the rook (36... Rxf2+).
|Aug-10-11|| ||stst: Brute force by the front line RxP+ does not work. The N also does not help.
The quiet line maybe somewhat hidden:
34.R1d1 (threatening R7d8):
IF (A)34....QxN, 35.R7xg7+ Kh8, 36.Qg7#
IF (B)34....Qh3+, 35.Kg1 Bf2+, 36.Kh1 Qg4, 37.Rxf8+ KxR, 38.R1d8#
IF in between the Bk Q tries to get back to the back rank, say @36...Qh5, 37.Rxg7+ repeats the (A) line: Kh8, and Qg7# follows immediately.
|Aug-10-11|| ||sevenseaman: Thanks <psmith>. I think my move numbering went awry. I have used Rd6 as the 32nd move for Black rather than rightly using it as the 33rd.|
<NM JRouselle>'s suggestion about trading Rs is still not clear to me though.
It comes out as 33...Rd6 34. Rxg7+? Qxg7 35. Qxc5 . A loss of exchange for White? In fact White is worse off, as noted by you as well. So what was <NM JRouselle> trying to say?
|Aug-10-11|| ||naruto00122: how I missed this one?
|Aug-11-11|| ||Dr. J: <sevenseaman> I do believe you're right. After 1...Rd6 2 Rxg7+ Qxg7 3 Qxc5, the win for Black, even if it exists, would be much harder.|
