|May-26-05|| ||patzer2: Jonathan Kinlay's 50...b2!! is a hard move to classify. In one sense it is a clearance move, freeing b3 for the Rook's check to set up a decisive followup discovered check. It can also be considered a deflection move, winning decisive material after 51. Rxb2 Bd2+! In another sense, it is a pursuit combination, creating a mating web for the White King. |
|May-26-05|| ||patzer2: A bit of summary analysis:
<49. Kc3?!> (better is 49. Ree2=) <49... Ba4 50. Bb1?> is the losing move (better is 50. Kb2 =) <50...b2!!> this combined clearance and deflection sets up a decisive King Hunt and Mate in the game continuation <51. c5> (White can avoid the mating net, but loses decisive material to a deflection and discovered check after 51. Rxb2 Bd2+! 52. Rxd2 Rb3+! 53. Kc2 Re3+! 54. Kb2 Rxe1 ) <51...Rb3+ 52. Kc4 d5+!> forces the King into a mating web after <53. Kxd5 Rg8 54. c6 Rd8+> (even faster is mate-in-four with 54... Rc3! 55. Nxf6 Kxf6 56. Kd6 Rxc6+ 57. Kd7 Rcc8+ 58. Kd6 Rgd8#) <55. Kc5 Rb5+ 56. Kc4 Rd4+ 57. Kc3 Rb3+ 58.Kc2 Rc4+ 0-1> and White resigned in the face of 59. Kd1 Re3+ 60. Bc2 (60. Kd2 Rd4+ 61. Bd3 Rdxd3#) 60... b1=Q+ 61. Kd2 Qxe1# 0-1
|Aug-15-05|| ||RabbitBasher: Torre had just beaten Karpov in this line (his first loss in several years) and this was my first game vs a grandmaster, so I was a little nervous before the start. The game was adjourned and I assessed it as equal - no way for either side to make progress. I was playing over the position with my friend Robert Bellin when I say spotted the ... b2 move and started laughing - "look what happens if he allows this!". Anyway, he did allow it, much to my amazement.
The analysis by Patzer2 is good. I missed a faster win, as he points out. Actually I didn't miss it, I saw it at the time - I was just trying to make sure of the win!|

White missed a startling continuation, as pointed out by Pavlovic: 23.Nxf6!!! and, suddenly, White is winning.

|Jan-18-15|| ||kamagong24: great game by GM Torre!|
|Jan-18-15|| ||al wazir: Torre lost.|
|Jan-18-15|| ||ndg2: What happens, if white plays 51.Ba2? 51..Bc1?|
|Jan-18-15|| ||kamagong24: <al wazir> still looks great to me! hahaha|
|Jan-18-15|| ||ozu: I can say I got the 1st move right the last couple days..with the basic follow up ideas as well.. I'm not sure what I'm feeling right now...happy... Happy|
|Jan-18-15|| ||agb2002: Black has the bishop pair for a bishop and a knight.|
The knight is trapped and defenseless but cannot be easily attacked. The white king has only two available squares. This suggests 50... b2, threatening 51... Rb3+:
A) 51.Rxb2 Bd2+ 52.Rxd2 (52.Kxd2 Rxb2+ with a won ending) 52... Rb3+ 53.Kc2 Re3+ followed by 54... Rxe1 and Black is practically a rook ahead.
B) 51.Bc2 Bxc2 52.Kxc2 (52.Rxc2 b1=Q wins) 52... Rxe4 53.Rb1 (53.Rxe4 b1=Q+ wins; 53.Rge2 Rxe2+ 54.Rxe2 b1=Q+ wins) 53... Rxc4+ 54.Kd3 (54.Kd1 Rc1+ wins) 54... Rc1 55.Rg1 Rxg1 wins.
C) 51.Ba2 Rxe4
C.1) 52.Rxe4 b1=Q 53.Bxb1 Rb3+ 54.Kc2 Rxg3+ 55.Kb2 Rxg2+ 56.Kc3 (or 56.Ka1) 56... Bd1 wins the knight and a pawn.
C.2) 52.Rxb2 Rxb2 53.Rxe4 Rxa2 wins the bishop.
C.3) 52.Rge2 Rxe2 53.Rxe2 b1=Q wins the bishop.
C.4) 52.Rb1 Re3+ 53.Kd2 Rxg3+ wins a rook.
D) 51.c5 Rb3+ 52.Kc4 (52.Kc2 Rxg3+ wins) 52... d5+ 53.Kxd5 Rg8
D.1) 54.Kc4 Rd8 55.c6 Rd4+ 56.Kc5 Rb5#.
D.2) 54.c6 Rd8+ 55.Kc5 (55.Kc4 Rd4+ 56.Kc5 Rb5#) 55... Rb5+ 56.Kc4 Rd4+ 57.Kc3 Rb3+ 58.Kc2 Rxg3+ wins.
D.3) 54.Bc2 Rd8+ 54.Kc4 Rd4#.
D.4) 54.Rd1 or 54.Rd2 only loses material after 54... Rd8+.
D.5) 54.Nxf6 Kxf6 only loses material.
|Jan-18-15|| ||gofer: What do they say about knights on the rim? Positionally
white is a piece down, but that may not remain so for ever...|
<50 ... b2>
Black threatens 1 ... Rb3+ 2 Kc2 Rxg3+ and defending
against it is not as simple as it seems!
51 Ba2 Rxe4!
52 Rxe4 b1=Q
53 Bxb1 Rb3+!
54 Kc2 Rxg3+
55 Kb2 Rxg2+
56 Kc3 Bd1 (Ka1 Bc1 mating)
But black is also threatening the simple pawn promotion!
51 Bc2 Bc1!
So white must accept the pawn sacrifice.
<51 Rxb2 Bd2+!>
52 Kxd2 Rxb2+
<52 Rxd2 Rb3+>
<53 Kc2 Re3+>
<54 Kb2 Rxe1>

White has survived, but is an exchange down. But worse than
that Nh5 is still dim. Where as Rg4 can come into the action
very swiftly Rg8, Rb8+. If white trades bishops the rook pair
will sweep up all the loose pawns white and I mean ALL of them!
If white keeps the bishops on the board Rg4 will come round
and pulverise the white king... ...and just for good measure
after playing Rg8, Bd1 will mop up the lose knight on h5...
Ahhh! But given how swiftly white lost after 51 c5? I doubt
it was the strongest response. Rxb2 still looks like white
will make it to an end game. <51 c5> led to a virtually
|Jan-18-15|| ||The Rocket: I must be insane! I also found the faster stronger rc3, rejected in the game.|
|Jan-18-15|| ||mistreaver: Sunday. Black to play. Insane. 50...?
Black has really dominating position, but he has yet to find that critical breakthrough.
His strength consists in strong pawn on b3 and the out of play kngiht on h5.
My first thought was to play blitz like move
but then i realized that white doesn't have to take but can simply go fore say Ree2 and black has achieved nothing.
Then i noticed this combination that looks very tempting:
50 ... b2! (this just seems to lose a pawn)
51 Rxb2 (white doesn't really have a choice since Rb3+ is a terrible threat)
51 ... Bd2+ (this is the point, black either wins the exchange or gets in Rb3+, even if he has to give material)
52 Rxd2 Rb3+
And now we should find some fatal blow.
53 ... Re3+
winning the rook on e1 seems to seal the deal. Black has some technique to show but it should be easy.
Time to check and see.
Hmm, ok i noticed the winning idea and since this is a puzzle i knew it was working, but i should have probably considered more deeply other alternatives (altough i had feeling that if it works on Rxb2 it works in every instance).
|Jan-18-15|| ||Manic: Can anyone please provide the full continuation after pulsar's/Pavlovic's suggestion of 23.Nxf6 ?|
I'm looking at it and am stone cold lost in what the continuation may entail after 23...Kxf6 (other than presumably 24.Qh5)
|Jan-18-15|| ||CHESSTTCAMPS: Black has 2 bishops for B+N in this semi-closed endgame position. White's knight is trapped on h5, but it is also inaccessible to capture and it is tying down the black king to the f-pawn, while helping to keep the queen-side closed by protecting the g-pawn. In searching for winning ideas for black, I first looked briefly at Bf4 to apply additional pressure on the g-pawn, but there is nothing in that. In any closed or semi-closed position, one should always consider pawn breaks, and black has only two available - d5 and b2. The first looks to be losing and I didn't see anything good in 50... b2 51.Rxb2 - that is, not until about the 3rd or 4th look. Then, there it was:|
50... b2! The threat is 51... Rb3#! (Who doesn't like off-the-edge checkmates in an endgame?)
A. 51.Rxb2(?) Bd2+! 52.Rxd2 Rb3+ 53.Kc2 Rxb3+ 54.Kd1 Rxb2 and white's endgame is hopeless down an exchange, because the h-pawn must fall and the knight is now vulnerable.
A.1 52.Kxd2 Rxb2+ 53.Kc3 Rb3+ 54.Kd2 (Kc2 Rbxg3+) Rg8 55.Rc1 (Bc2 Rb2 56.Rc1 Rc8 57.Kc3 Rxc2+ 58.Rxc2 Bxc2 59.Kxc2 Rxc4+ with a won endgame) 55... Rgb8 56.Bd3 Rxa3 and black's rooks are in control.
B. 51.c5 Rb3+ 52.Kxc4 (Kc2 Rbxg3+ wins) d5+! 53.Kxd5 Rg8 54.c6 (Bc2 Rd8+ 55.Kc4 Rd4#) Rd8+ 55.Kc5 Rc8 56.Rc1 (Rc2 Rxc6+ 57.Kd5 Rd3#) Rxc6+ 57.Kd5 Rxc1 followed by Rb5#
C. 51.Kd3 Rb3+ 52.Ke2 Rg8 53.Kf1 (not 53.Bc2? Re3+ 54.Kd1 Rxe1 55.Kxe1 Bxc2 56.Rxc2 b1=Q wins) Rgb8, to be followed by Rxa3, Bc1, and Ra1 looks to be the right winning plan for black.
Time for review....
|Jan-18-15|| ||Cheapo by the Dozen: Near-total whiff for me. It was obvious that ... b2 was probably the move. But I didn't even see that in the Rxb2 line, ... Rb3+ would lead to a discovered check.|
|Jan-18-15|| ||Penguincw: I got 50...b2, hoping that black would follow up with 51.Rxb2 Bd2+ 52.Rxd2 Rb3+ 53.Kc2, followed by some discovered check.|
|Jan-18-15|| ||Edeltalent: 50...? Black to move
It's a somewhat peculiar position with an imbalanced pawn structure and several pieces in awkward squares - most noticeably the white knight, which is stuck on the rim with no way out (but how to get to him?). Black is clearly the one calling the shots. An active plan for White is hard to spot, maybe a break with c5 at some point, but it seems very far-fetched.
Not easy to suggest concrete moves for Black, let alone forcing ones. The weakness on e4 is well defended. A breakthrough with 50...b2 or 50...d5 doesn't seem possible at the moment. I'm reluctant to play 50...Bf4, as it gives White the chance to solve the problem with his knight by exchanging it. Besides, it doesn't even threaten anything yet.
The quiet 50...Rb8 seems like a decent move. The idea is to go Rbg8 with the threat of Rxh4 and picking up the knight. My hope is White will have to concede an entry square for the darksquared Bishop, e.g. 50...Rb8 51.Bd3 Rbg8 52.Reg1 Be3 53.Re1 Bd4+ or 52.Ree2 Bc1. But the Rg2 can also step aside and I don't think the exchange sacrifice on g3 would be sound, e.g. 50...Rb8 51.Rge2 Rbg8 52.Rb2 Rxg3+ 53.Nxg3 Rxg3+ 54.Kb4 and Black has dug his own grave.
I've looked at 50...Rb8 51.Rge2 d5 52.cxd5 Rc8+ or 52.exd5 Rc8, but can't make it work, the white bishop can stabilize the weak pawns, sometimes the white king runs to b4 and questions the Ba4.
Another thought about 50...b2 51.Rxb2 Rxb2 52.Kxb2 Bd2, claiming the white king is a little boxed in and the other bishop might miraculously make it to d1, winning the knight, but it's absolutely not there. In the process though I've finally spotted the tactical idea, 50...b2 51.Rxb2 Bd2+.

Suddenly everything works smoothly. 52.Kxd2 Rxb2+ 53.Kc3 Rb3+ or 53.Kc1 Rg2 and White is too passive to offer much resistance.
52.Rxd2 Rb3+ 53.Kc2 Re3+ 54.Kb2 Rxe1 and again White has to watch helplessly how Black brings the other rook for the decision. By the way, this last variation reminds me of Anand vs Kasparov, 1995
50...b2 51.Ba2 or 51.Bc2 don't help, as both are met by 51...Bc1 and the infiltration happens under even worse conditions.
|Jan-18-15|| ||Edeltalent: One has to be quite desperate (or a bigger optimist than Bogoljubov) to try to run forward into heavy fire with a king foresaken by all his fellow pieces.|
|Jan-18-15|| ||CHESSTTCAMPS: <50... b2! The threat is 51... Rb3#! (Who doesn't like off-the-edge checkmates in an endgame?> I'm glad nobody else had this hallucination!|
