|Jan-20-11|| ||gourav27: The idea is simple.Ra1 +finishes the task|
|Jan-20-11|| ||culei: Gourav27 how about nb1|
|Jan-20-11|| ||Formula7: 23...Ra1+ and now;
A) 24.Bxa1 Qa3+
A1) 25.Bb2 Qxb2#
A2) 25.Kb1 Qxa1+ 26.Kc2 Nb4#
A3) 25.Kc2 Nb4+ 26.Kb1 Qxa1#
B) 24.Nb1 Rxb1+ 25.Kxb1 Qxe4+ loses two knights for a rook
C) 24.Kc2 Nb4#
Time to check.
|Jan-20-11|| ||TeaChess: Strange. Ra1+ didn't come to my mind at all. How about 23. ... Ra2?|
|Jan-20-11|| ||An Englishman: Good Evening: One thing is for certain--0-0-0 was a polite request for trouble, and Polgar was only too happy to oblige. 6.0-0 was probably an improvement upon 6.d4, too.|
|Jan-20-11|| ||rilkefan: In my 24. Nb1 Nb4 line above, I should have considered 26. Kd2, where I seem to be ending up with a draw.|
|Jan-20-11|| ||vanytchouck: Too, toot, too easy (rather a monday one) :
Typically the first kind of move i'll check (even in serious tournament) on the board.
The question is whether this move is really that good ...
25. Bxa1 Qa3 + and then?
And then you see the knight, ready to come to b4 attacking both c2 and d3.
With the Bg7, there is no way the white kig can escape ...
26. Kc2 Nb4 and 27... mate
24.Kc2 Nb4 # !!!
Too, too, too easy one!
|Jan-20-11|| ||Stormbringer: Didn't find it, could not figure out how to beat Nb1, and I figured the other potential moves Bg4 (skewering Queen and Rook) were too small a gain for decisive victory.|
|Jan-20-11|| ||David2009: A Kolev vs Judit Polgar, 1993 Black 23...?|
23...Ra1+ looks safe seeing 24 Bxa1 Qxa1+ 25 Kc2 Nb4# no time for more just time to check
==== Must dash.
|Jan-20-11|| ||Freelix: 21...Rxa3 is also a nice move. Even without calculating every variation, a R is well worth trading for B and pawn plus an exposed K. Here, Black has a winning attack, thanks to the crucial opening of the main diagonal with e4.|
|Jan-20-11|| ||vanytchouck: Hé, hé ... I didn't even think about Nb1.
Not so easy then ; - D (even if it's not that difficult) ...
|Jan-20-11|| ||gmalino: Material even, a slightly better pawn structure for black, white threatens to win the exchange by Bxa3.|
Doesn't lead to anywhere, but after 2 min of searching I found
So if there is a way to avoid mate it is not taking the Rook on a1
doesn't help either.
Looks like the a1-h8 diagonal is simply to strong for black.
|Jan-20-11|| ||gmalino: like <vantytchouk> <dzchiel> and a few others I completely ignored Nb1!
Why is it that I ALWAYS miss details? Concentration? Character? Coffee?|
The week and my whole live are full of this missings, hmmm.
I don't care..
Instead keep smiling.
It's a rainy day oh yeah....
|Jan-20-11|| ||plateos: Black appears to able to force mate with the power of Lg7 & Rc6.|
23. ... Ra1+
24. Lxa1 Da3+ (24. Kc2 Rb4#)
25. Kc2 Rb4+ (25. Kb1 Dxa1, Kc2 Rb4#
26. Kb1 Dxa1# (25. Lb2 Dxb2#)
Rather simple for Thursday.
|Jan-20-11|| ||agb2002: Black has the bishop pair for a bishop and a knight.|
White cannot take the rook with 24.Bxa3 because of 24... Qxa3+ 25.Kc2 (25.Kb1 Qb2#) Qb2+ 26.Kd3 Ne5#. However, White would like to play 24.Nf6+ followed by Nc4 with the double threat Nxa3 and Nxd7.
These details suggest 23... Ra1+:
A) 24.Bxa1 Qa3+
A.1) 25.Kc2 Nb4+ 26.Kb1 Qxa1#.
A.2) 25.Kb1 Qxa1+ 26.Kc2 Nb4#.
A.3) 25.Bb2 Qxb2#.
B) 24.Kc2 Nb4#.
|Jan-20-11|| ||agb2002: I also overlooked
C) 24.Nb1 Rxb1+ 25.Kxb1 Qxe4+ followed by Bf5, Nb4, etc.
|Jan-20-11|| ||gofer: White has one quick trick up her sleeve; Nf6+ blocking the a1-h8 diagonal for the bishop and effectively forcing Bxf6 as the reply
as black cannot afford to give white a tempo by moving the king. So we either need to pay check immediately or realise that we are
going into this attack without the wonderful DSB!
I looked at Bxb2+, Bf5, Ra2 and each time I was seeing that Nb4+ was horrible for white if our DSB was still controlling the a1-h8
diagonal. So finally, and perhaps a little late in the day, I saw Ra1+!
<23 ... Ra1+>
<24 Bxa1 Qa3+!> (Kc2 Nb4#)
<25 Kc2 Nb4+> (25 Bb2 Qxb2# and 25 Kb1 Qxa1+ 26 Kc2 Nb4#)
<26 Kb1 Qxa1#>
So once you see how all-inspiring Nb4+ is and how we can happily give away the rook, the rest is easy! Time to check...
|Jan-20-11|| ||daveinsatiable: Ra1 jumped out at me straight away, I saw that Nb1 was the only defence, figured that Rxb1, Kxb1, Qxe4 left white a tempo to move the bishop on d7 to a safer spot and thus N+B for R up, hoped that was good enough (which it probably is - not for me against Crafty, but surely for Polgar), wondered if I'd missed a more clear-cut variation or better defence, turned to the kibitzing expecting to be shot down. And whatdoyouknow, I nailed it.|
|Jan-20-11|| ||OhioChessFan: <David: 23...Ra1+ looks safe seeing 24 Bxa1 Qxa1+ 25 Kc2 Nb4# no time for more just time to check ==== Must dash. >|
26. Kb1 ;)
|Jan-20-11|| ||OhioChessFan: As for the game, anyone else think Polgar was channeling Petrosian with the a and h Pawn pushes?|
|Jan-20-11|| ||Ratt Boy: I'm not sure.
23...a1+ looks like a forcing move.
24.xa1?, a3+ 25.c2, b4#
Better for W is 24.b1, xe4 25.xa1, g4 26.d2, xd1 27.xg7, b3 28.c3 (b2?, h1+), e5 and the threat of ...d3+ forces xe5, and Black has gained a big fat for her efforts.
Looks like a lot of work for a little guy. I'm probably missing something. Time to check.
|Jan-20-11|| ||OhioChessFan: <dz: 24 Nb1 Bg4 25 f3 Rxb1+ 26 Kxb1 Qxe4+ 27 fxe4 Bxe2 28 Rd7 Ne5 29 Rxc7 Bd3+ 30 Ka1 Bxe4 31 Re7 Kf8 32 Rxe5 Bxe5 33 Bxe5>|
25...Qxe4 and the rest is easy for someone like Polgar.
|Jan-20-11|| ||gofer: I am really struggling to find a win against Crafty EGT (with colours reversed)... ...you try! :-)|
|Jan-20-11|| ||Ratt Boy: Dangit, I missed the obvious 24...xb1+. But I found better moves than Kolev, so I'm giving myself substantial partial cred here.|
|Jan-20-11|| ||SU1989: I found <24..Rxb1+>, however went with 25..Bxa1 followed by 26..Qxa3+.|
