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...

Endgames, part 1: Rook against Bishop — A superb lesson from Magnus Carlsen in endgame technique. It's been a while since we looked at the endgame, so this week we begin a short series on this often neglected area with a terrific demonstration of endgame technique from the ever-improving chess world No 1 Magnus Carlsen. Although White has the advantage of rook against bishop, Black has an extra pawn and a solid position on the chess board. How did Carlsen make progress? RB I'm pretty sure the answer lies in g4. The question is whether to nudge the pawn forward immediately or whether some preparation is needed first, perhaps exchanging on d5 or advancing the king to e3. The only way is concrete calculation, so let's see what ...

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?

Dortmund Begins — The Sparkassen Chess-Meeting (an odd name, to be sure) began Thursday in Dortmund. Though the chess tournament is not at the level of Linares or Corus, it still attracts top players, notably Vladimir Kramnik, the former world chess champion from Russia. Kramnik has been associated with Dortmund, as the chess event is often referred to, for many years because he has won the tournament nine times, far more than any other. He first won it in 1995 and is the defending champion this year. The tournament is a double-round robin this year, meaning each competitor plays all the others twice, once with each color. In addition to Kramnik, the No. 4 chess player in the world, the field includes ...

Play online chess | 7.Kg1

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,

Zhao and Zatonskih Lead Chess Championships — Anna Zatonskih, the defending chess champion, took the lead of the U.S. Women’s Championship on Wednesday, while Parker Zhao, the ninth seed, solidified his grip on the U.S. Junior Championship. The two chess tournaments are being held concurrently at the Chess Club and Scholastic Center of Saint Louis. Zatonskih had shared the lead for the last few rounds with Irina Krush, the top seed. But in Round 5 on Wednesday, Zatonskih beat Iryna Zenyuk, while Krush only drew against Camilla Baginskaite. Zatonskih now leads with 4.5 points, while Krush and Tatev Abrahamyan, who beat Abby Marshall on Wednesday, have 4 each. In the junior championship, Zhao, who ...

... 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 Chess Odyssey — One single square can make a big difference in a chess game. It helped me to launch one of my longest combinations against Anatoly Karpov in Caracas 40 years ago. It was a memorable chess tournament for both of us. Karpov arrived in Venezuela as the reigning world junior champion. He played well enough in Caracas to become the world's youngest chess grandmaster at that time, at age 19, and his brilliant career began to take shape. In 1971 in Moscow, he clinched the first major tournament victory, sharing first place with the three-time Soviet champion Leonid Stein at the prestigious Alekhine Memorial tournament. In 1975 he was crowned the world chess champion. This year ...

Fast Pace Continues at Two U.S. Chess Championships — The top two seeds in the U.S. Women’s Chess Championship could make no headway against each other and drew their Round 3 game on Monday. But their two nearest competitors lost, so Irina Krush and Anna Zatonskih now lead the chess tournament by half a point over Tatev Abrahamyan, Alisa Melekhina (who lost to Abrahamyan on Monday) and Iryna Zenyuk, who lost on Monday to Beatriz Marinello. In the U.S. Junior Chess Championship, which is being held concurrently at the Chess Club and Scholastic Center of Saint Louis, Warren Harper, the seventh seed, is the surprising leader after three rounds with a perfect score. His play so far has been stellar and on Monday he demolished his ...

... 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.
