Kibitzer's Corner
Nov-09-04   Poisonpawns: Is this Korchnoi attack unsound? It seems pretty tough in this game.I am scared to play against this in the Dutch defense.
Nov-12-04   Poisonpawns: 9..Bg7 10.0-0-0 Qa5 11.Bh6 Bxh6 12.Qxh6 Be6 13.Kb1 Rf8 14.Bg2 Nbd7 15.Nge2 0-0-0 16.d5 cxd5 17.Nf4 Bf7 18.Nfxd5 This is still slightly unclear to me can anyone help with analysis? This seems like a good weapon against the dutch.
Nov-23-04   Poisonpawns: Does anyone know how to play for black against this line? I was thinking, first of all instead of 5...d6 to play d5, which could be followed by 6.e5 Bf5
Nov-23-04   Swindler: Ain't this an idea in the Sicilian (though reversed)? 1.e4 c5 2.a3? Saw a new book about it.
Nov-23-04   I sacrifice like Tal: I'll put it this way.

"Black has done nothing wrong."

So, White's 'attack' should be unsound in some sense. I think Blac is fine is he can castle queenside and offset the white centre comehow. Or maybe playing e6 or d6 instead of Nf6. I'm not sure. But it IS interesting.

Nov-24-04   Poisonpawns: Yes thats true but does any Dutch player have experience and or analysis in this line. It would be nice to here from a GM or IM :-)
Nov-24-04   drukenknight: why doesnt black push his own h pawn in order to put the question to the B? You will mess up these gambit lines all the time if you dont attempt to force exchanges.
Apr-15-05   Poisonpawns: Just wanted to say I am 2-0 now after using this line as white in tourneys,against 2100+ opposition.This is a nasty anti-dutch weapon!

  refutor: <poisonpawns> did you come to a conclusion about ...d5 v. ...d6?
Nov-16-05   mrbasso: 3...d5! is the best move.
The best way to refute a Gambit is to decline it.
May-18-09   Poisonpawns: I claimed another victim 1955 rated player this weekend in this line.I just give the opening 1.d4 f5 2.h3 d6 3.g4 fxg4 5.hxg4 Bxg4 6.f3 Be6 7.e4 the rest went quite similar to the korchnoi game.The opponent had the extra pawn, but was unable to solve his positional problems.

  ajile: <mrbasso: 3...d5! is the best move. The best way to refute a Gambit is to decline it.>

This I think depends on the defender's temperament. Also there are openings where Black might give the material back but not immediately. So there are actually 3 different scenarios.

Decline
Accept
Accept but give back later

Basically the usual theme is that the Gambiteer is trading material for a time/developing advantage. If he is successful he will get the material back and/or develop a winning attack. However the downside is that if the player accepting the gambit can hold off the attack then he will have a material advantage.

If you are a patient good defender and you play well under long term pressure then accepting the gambit would be the best way for YOU to attempt to refute the gambit.

If you don't play well under these circumstances then either declining or returning the material quickly is probably your best way to attempt to refute the gambit.

For example the King's Gambit. Both the accepted variation (1.e4 e5 2.f4 exf4) and the Falkbeer Counter Gambit (1.e4 e5 2.f4 d5) work well for Black but lead to very different types of games.

Bobby Fischer of course would have said to take the pawn and make White prove he has something tangible.
