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...

U.S. chess championship felt like a tornado — I wasn’t at the airport last month, but I still feel like I got hit by a tornado. For some players, the 2011 U.S. Chess Championship concluded April 29, but unfortunately April 21 was my last game. On the bright side, I had a ringside seat for the remainder of the chess matches, including the heart-pounding women’s finals, which went into an Armageddon round (that’s triple overtime)! The chess tournament featured an interesting format – the top two players from two eight-player round-robin groups qualified for the semi-final matches. The two semi-finalists from the “A” group were no surprise. Reigning Chess Champion and Grandmaster (GM) Gata Kamsky and last year’s runner-up, GM Yury Shulman, easily ...

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?

Chess notes — China is steadily gaining the respect of the world chess community as some of its players have emerged to become substantially dangerous competitors in the West. So the Chinese chess championships have been watched with interest this year. In the 2011 championship, a dark horse has once again emerged to take first place: Ding Liren. The 18-year-old won the title in 2009 (in part because of a defaulted game), despite being one of the lower-rated chess players in the field. His score this year was a startling 9-2 against such well-known chess grandmasters as Yue Wang and Xiangzhi Bu. Ding has only occasionally played in the West. World Women’s chess champion Hou Yifan scored an impressive ...

Play online 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,

Chess: A pawn endgame dilemma — Should White force a pawn endgame? It's a tricky decision... RB: My first reaction is: no, White should definitely not exchange. After 1 Nf4 Bxf4 2 Kxf4 Kd5 it seems to me as though Black is definitely better. But what else does White have? I don't want to drop the king back and allow the black king to invade. I could try 1 a4, but after 1…b6 I'm back to my original dilemma. It makes me nervous, but let's see what happens after 1 Nf4. Black takes, obviously, 1…Bxf4 2 Kxf4 Kd5. Now what? As long as ...

... 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...)

For Want of a Draw, a Player Loses the U.S. Chess Title — Yury Shulman forgot the old saying that a tie is better than a loss during his quest to win the United States Chess Championship last week. And that opened the door for Gata Kamsky to capture his second straight title. Kamsky and Shulman met in the tournament final, as they did last year, when four competitors competed in round robin play. Kamsky and Shulman emerged as the top scorers of that round and met in an Armageddon game, in which White has more time but Black only has to draw to be declared the winner. No Armageddon was needed at this year’s final, which ended Wednesday in St. Louis, because Kamsky won the first game and the second was drawn. The first game would ...

Yang-Fan Zhou breaks English international master drought — England used to produce one or two teenage international masters a year in the 1970s and 1980s, the golden era when the Olympiad team advanced to world No2 behind the Soviet Union. Now Russia and India lead in junior chess while, since David Howell became a grandmaster in 2007, the only new English GMs and IMs have been adults. Yang-Fan Zhou, 16, broke the drought last week when he scored his final IM norm at Coulsdon. It followed Zhou's eye-catching 9/9 at Brighton in February and the International Chess Federation (Fide) should formally award him his IM title in a few weeks' time. The sixth-former from Whitgift School in Croydon has made an 80-point surge up the world chess ratings, reflecting ...

... 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.
