Play online chess |  Subject: Traxler Gambit
Message:
I hope there are someone who knows enough about it.After these moves:
1 e4 e5
2 Nf3 Nc6
3 Fc4 Nf6
4 Ag5 Fc5
5 Axf7 Fxf2
6 Kxf2 Axe4+
7 Ke3 Qh4
Black has a great positional advantage and there are combinations that takes you to the victory.For example;
8.Nxh8 Qf4+
9.Ke2 Qf2+
10.Kd3 Ab4+
11.Kxe4 Qf4#
But if white plays 6.Kf1 instead of capturing the bishop,black's both rook and queen are under the attack.So,black loses his rook.And after this,how must black play to have a chance to have a positional advantage or take a piece?
I thought about of it but couldnt solve the problem.I hope there are someone who can help me here.

After 6.Kf1 Qe7 7.Nxh8 d5 8.exd5 Nd4, Black has reasonable attacking chances.

1. If White takes the f2-bishop, then after 6...Nxe4+ 7.Kg1 is (according the Estrin) the best move.
w
If 7.Ke3 Qh4 8.Qf3 Ng5! (if 8...Nc4 9.Nxh8 is playable)
9.Nxg5 Qxg5+ 10.Kd3 d5 11.Bxd5 Bf5+ 12.Kc3 Nd4
13.d3 Qe7 "with as immensely strong attack..." (Estrin).
The g1-retreat might well be good enough for the draw, though White will be on the rack for a long time to come.
2. The effect of 6.Kf1 is to prevent Black's gaining a tempo with the knight-check on e4. Black has, perforce, to make a quiet move 6...Qe2 whereat White takes the rook. But then 7...d5 and Bl;ack gets a dangerous attack:
w
A sample line runs
8.exd5 Nd4 9.Kxf2? Bg4 10.Qf1 Ne4+ 11.Kg1 Ne2+ and Black wins (12.Bxe2 Qc5+ etc).
The Traxler - indeed just about the whole Two Knights' Defence family - is one of the richest and most fascinating opening lines of play Chess has to show. Pity about the Ruy Lopez...

London Chess Classic: Kramnik's lesson in positional play — McShane-Kramnik, London 2009. Black to play. With two rounds to go in the London Chess Classic, the Norwegian chess prodigy Magnus Carlsen looks set to win the tournament. Vladimir Kramnik, his main rival, is in second place. In this game from round three, Kramnik displayed his refined positional understanding. RB I've been following this tournament online, but I missed this particular game, and more's the pity because I can't find a good continuation for Black. Clearly Kramnik has the better game – the two centralised knights look very threatening – but how to convert Black's positional superiority into a winning position? 1...Nxd2 2 Nxd2 doesn't lead anywhere and ...

Thanks for your answer but your answer created a new question in my brain.
"1. If White takes the f2-bishop, then after 6...Nxe4+ 7.Kg1 is (according the Estrin) the best move" you said like that but now how must black go on not to lose advantage?

Gelfand Wins World Chess Cup — Boris Gelfand of Israel is the 2009 World Cup champion. Gelfand won the title by beating Ruslan Ponomariov of Ukraine in a playoff on Monday. The first four games of the playoff were rapid games (25 minutes per player per game) and Gelfand took the lead by winning the second game. But Ponomariov, with his back to the wall, won the last rapid game to tie the match up again. The playoff then went to blitz chess (5 minutes per player per game) and Gelfand once again took the lead by beating Ponomariov in the first game when he managed to trap Ponomariov’s queen in 21 moves. Ponomariov rallied again, winning the second game. But Gelfand won the third and Ponomariov ...

Things get pretty theoretical after this line.
The main line (bearing in mind the theory I have available is 30 years old!) goes:
7.Kg1 Qh4 8.g3 (8.Qf1?) 8...Nxg3 9.Nxh8 (for the consequences of 9.hxg3, see infra) 9...d5 (9...Nd4; 9...Ne4?; 9...Nxa1?!) 10.Qf3 Qd4+ 11.Kg2 Nf5
12.c3 Qxc4 13.d3 Qh4 14.Qxd5 (14.Rg1!?) 14...Ne3+ 15.Bxe3 Ba3+ and Black has no more than a perpetual.
Note that both sides can deviate quite a bit, so there may be buried in all this some decisive resource for Black - or White.
Back to the 9.axg3 line, here's a game played by correspondence between the readers of a Soviet schoolboys' daily paper and Mikhail Tal:
White: "Pionierskaya Pravda" Black: M. Tal
1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 Bc5
5.Nxf7 Bxf2+ 6.Kxf2 Nxe4+ 7.Kg1 Qh4 8.g3 Nxg3
w
9.hxg3 Qxg3+ 10.Kf1 Rf8 11.Qh5 d5(!) 12.Bxd5 Nd4!?
(Apparently 12...Nb4! is better, using the attack on the bishop further to develop Black's game and force exchanges whilst retaining the pressure on White's game)
13.Qh2 Qg4 14.Qxe5+ Be6 15.Bxe6 Qf3+ 16.Kg1 Ne2+
17.Kh2 Qf2+ 18.Kh3 Qf3+ 19.Kh4 Qf2+ (19...Qxh1+?? 20.Bh3+ Kxf7 21.Qe6#)
At this point, White could secure the draw by bringing the K back to h3, and a perpetual. But the lads hoped to make something of their material plus...
20.Kh5? Rxf7 21.Bxf7++ Kxf7 22.Rh2 Qf3+ 23.Kh4 g5+!
24.Qxg5 Rg8 25.Qh5+ Qxh5+ 26.Kxh5 ...
At this point,
b
Black forced the draw by...
26...Ng3+ 27.Kh6 Nf5+ 28.Kxh7 Rg7+ and a perpetual.
But from the diagram position, a Moscow schoolboy found that Black could have forced a win - a checkmate - even with such scanty material available.
See if you can find it!
Cheers,

A tragic knight — The London Chess Classic, a fabulously organized eight-player elite tournament, shaped up as a confrontation between two great chess grandmasters, the top-rated Magnus Carlsen of Norway and the former world chess champion Vladimir Kramnik of Russia. By the luck of draw, they met in the first round, and Carlsen won. The Norwegian GM was still in a clear lead on Sunday with four points in five rounds, a full point ahead of Kramnik. U.S. chess champion Hikaru Nakamura drew four games and lost one. The tournament concludes Tuesday. The Carlsen-Kramnik duel looked like a perfectly played game by the Norwegian, who took advantage of Kramnik's stranded knight. "If one piece is ...

... That Q on h5 is really the creamy complexioned monarch in drag. Sorry about that. (Normally I check over my postings in order to emend mistakes like this, but I've been finding lately they have been vanishing without trace. Not what you want to see when you have just spent a good half-hour on it...)

A Game Lasts 163 Moves, and That's Not Even a Record — Chess professionals are conditioned to games that take four to five hours and last about 50 moves, but occasionally play lasts much longer and the contest becomes a war of attrition. That is what happened between Nigel Short and Luke McShane of England in the first round of the London Chess Classic, which started on Tuesday. McShane, who had White, got a tiny advantage out of the opening, but Short defended well, and after 60 moves it seemed as if the game would end in a draw. But McShane, 25, persisted and Short, 44, was forced to continue to defend. It took McShane seven hours, and 163 moves, but he finally broke Short and forced him to resign. That ...

Soviet training methods still reign in the chess world — Two decades after the USSR broke up, Soviet training methods remain potent at the chess board. When the field of 128 was reduced to the quarter-finals in the current World Chess Cup, all eight grandmasters remaining had their education from Soviet coaches. The final four-game match now in progress to decide who qualifies for the 2010 candidates is between Ukraine's Ruslan Ponomariov, who won the 2002 World Cup as a teenager, and Boris Gelfand, the 41-year-old top seed. In the semi-finals Ponomariov beat Vlad Malakhov 4-2 while Gelfand eliminated Sergey Karjakin 2-0. In both the semi-final and in the game below the Israeli chess veteran defeated ...

... spotted the win for Black in that last diagram:
26...Nf4+ 27.Kh6 (If instead 27.Kh4 them ...h5 threatens mate by ...Rg4# - and it cannot be stopped [27.Kh4 h5 28.Rg2 Rxg2, then what?]) 27...Rg6+ 28.Kxh7 Rg7+ 29.Kh6 (29.Kh8 Ng6#) 29...Kg8!! (The key. White has no answer to the coming ...Rg6#).
Neat, eh?

if nxf7 I beat the cm 8000 (otb i am maybe1600)and in theory black should be ok, at least equal. The cm 8k is very weak and materialistic andif u feed it with the line nxf7?! ,it will follow a very greedy stupid line... bxf2+ ,kf1 ,qe7,nxh8, d5!! , exd5, nd4 etc. try it vs your achine if u have 1 very funny to beat the silly thing!!
the variation is seldom played cause after bxf7+! black is in trouble.
