Play computer 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...

Two Draws and a Blunder in Dortmund — One of the eternal frustrations of chess is that a well played game can be lost with one careless move. Shakhriyar Mamedyarov of Azerbaijan, the No. 6 chess player in the world, was reminded of this on Wednesday at the elite Sparkassen Chess-Meeting in Dortmunt, Germany. In Round 6, Mamedyarov was White against Arkadij Naiditsch of Germany. Mamedyarov got a clear edge out of the opening and had his opponent under pressure for much of the game. Naiditsch defended well and the game seemed to heading for a draw when Mamedyarov blundered, taking a knight with his rook that was defended by Naiditsch’s queen. As chess blunders go, it was not exactly colossal, but ...

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?

Shankland Is US Junior Chess Champion — Samuel Shankland, an 18-year-old international master, survived a three-way playoff on Tuesday to win the United States junior chess championship. Shankland was the No. 2 seed, but he beat Ray Robson, the top seed and a chess grandmaster, in an Armageddon game to claim the title. As there were three players tied for first, there were two playoff games. Robson, by virtue of having the better tie-breaker scores, met the winner of the first game. In that one, Shankland beat Parker Zhao. The playoff involved long Armageddon games, just like the one used at the U.S. Chess Championship earlier this year. Shankland and Zhao, each chess player secretly bid on how much time, up to ...

Play computer chess | 7.Kg1
Message:
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,
Ion

Krush Is US Women's Chess Champion; Playoff Will Decide US Junior — Irina Krush, 26, won the United States Women’s Championship on Monday by defeating Abby Marshall, 19, in the final round of the chess tournament.

... 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...)

Mamedyarov Leads in Dortmund — Shakhriyar Mamedyarov of Azerbaijan took over the lead of the elite Sparkassen Chess-Meeting tournament in Germany on Sunday after he drew his game while his co-leader, Ruslan Ponomariov of Ukraine, lost. Mamedyarov has 3 points after four rounds, Ponomariov has 2.5, Le Quang Liem of Vietnam, who beat Ponomariov, has 2, and Vladimir Kramnik of Russia, the defending chess champion, Peter Leko of Hungary and Arkadij Naiditsch of Germany are tied for last with 1.5 points each. The standings are startling as Kramnik, Leko and Naiditsch are all previous champions in Dortmund, while the top three players have never won there. Mamedyarov faced Vladimir Kramnik of Russia, the defending chess ...

Viktor Laznicka seals runaway World Open victory — The World Open in Philadelphia has been staged annually since the early 1970s, and although it has never quite justified its grandiose title it is still a huge magnet for chess players from grandmasters to novices. It is a big money event, with high entry fees but first prizes of several thousand dollars even for weaker sections. Its continued success reflects a ruthless policy by the organisers towards rating cheats, coupled with a highly flexible schedule. The final rounds are on Independence Day, but it is possible to compete anywhere between three and seven days and to re-enter if you start badly. For GMs in the top section, it can be a vicious battle. They normally get a minimum ...

... 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.
