There are well-known poisened pawn variations in the opening phase (Sicilian, Najdorf, PP-variation for instance). But also in the middle- and endgame this occurs. Fameous example is the second game in the Spassky-Fischer match (Rejkjavik 1972) for the WC title. Black (Fischer), on move 29, takes the pawn on h2 and will regret that later (although Fischer maintained that he had 'seen' this before making the move).
Entire game:
1.d4 Nf6 2.c4 e6 3.Nf3 d5 4.Nc3 Bb4 5.e3 0–0 6.Bd3 c5 7.0–0 Nc6 8.a3 Ba5 9.Ne2 dxc4 10.Bxc4 Bb6 11.dxc5 Qxd1 12.Rxd1 Bxc5 13.b4 Be7 14.Bb2 Bd7 15.Rac1 Rfd8 16.Ned4 Nxd4 17.Nxd4 Ba4 18.Bb3 Bxb3 19.Nxb3 Rxd1+ 20.Rxd1 Rc8 21.Kf1 Kf8 22.Ke2 Ne4 23.Rc1 Rxc1 24.Bxc1 f6 25.Na5 Nd6 26.Kd3 Bd8 27.Nc4 Bc7 28.Nxd6 Bxd6 29.b5 Bxh2 30.g3 h5 31.Ke2 h4 32.Kf3 Ke7 33.Kg2 hxg3 34.fxg3 Bxg3 35.Kxg3 Kd6 36.a4 Kd5 37.Ba3 Ke4 38.Bc5 a6 39.b6 f5 40.Kh4 f4 41.exf4 Kxf4 42.Kh5 Kf5 43.Be3 Ke4 44.Bf2 Kf5 45.Bh4 e5 46.Bg5 e4 47.Be3 Kf6 48.Kg4 Ke5 49.Kg5 Kd5 50.Kf5 a5 51.Bf2 g5 52.Kxg5 Kc4 53.Kf5 Kb4 54.Kxe4 Kxa4 55.Kd5 Kb5 56.Kd6 1-0.

What are they?
After 15...Qxb2, winning a supposedly 'free' pawn, white proceeds with a kingside attack. The cost of the pawn is that blacks queen is out of the way and cannot quickly aid the defence. In fact she is so poorly positioned after taking the 'poisoned pawn' she takes to further part in the game and black is quickly defeated!

(and yes, I did see that he had to take the knight.)
Originally posted by Bosse de NageThere is the poison pawn variation of the najdorf (and winawer as was mentioned, but I play the classical french lines so I know nothing about it).
Thanks for your comments...
Are there any, how you say, openings or tactics that attempt to set up poisoned pieces?
My little pamphlet here is yellow and so old as to not be in algebraic notation (the cover is lost so I dont have a copyright, but if memory serves its roughly '67). Anyway, it gives
1. e4 c5
2. Nf3 d6
3. d4 cxd4
4. Nxd4 Nf6
5. Nc3 a6
6. Bg5 e6
7. f4 Qb6
with the pawn on b2 being 'poisoned'
Actually if memory serves me right black can get away with taking one pawn at the expense of a kingside attack/uncomfortable game. Taking more than one is supposed to be sure defeat. That however, is among GM's with nearly flawless play.
Originally posted by zebanoThe most common line is 8. Qd2 Qxb2 9. Rb1 Qa3 so yes black can take the pawn. However white has enough compensation for the pawn and the position is still considered even.
