If your opponent cannot do anything active, then don't rush the position; instead you should let him sit there, suffer, and beg you for a draw.

{ Tim Harding's excellent postal chess magazine selected this as the best
correspondence chess game ever played as of 1999.|Runner up was
Timmerman-Anderson, Norwegian Jubilee 1994. Enjoy. } 1. e4 { C57: Two Knights:
Wilkes-Barre/Traxler and 4 Ng5 d5 5 exd5, unusual Black 5th moves } 1... e5 2. Nf3 Nc6 3. Bc4 Nf6 4. Ng5 d5 5. exd5 { If black play s the immediate 5... Nxd5?,
then white can crush black's position with 6. Nxf7! Typical play might look
like this: 6... Kxf7 7. Qf3+ Ke6 8. Nc3 Ncb4 9. Qe4 c6 10. a3 Na6 11. f4!
Nac7 12. fxe5 Ke7 13. d4 Ke8 14. O-O. } 5... b5 { The Ulvestad Variation. } 6. Bf1 { The odd looking retreat of this bishop is designed to prevent Qxg2 after
6... Qxd5 7. Nc3. Other alternatives give black a good game. For example, 6.
Bb3 Nd4 7. d6?! Nxb3 8. dxc7 Qxc7 9. axb3 abandons the center to black's very
active play for only a pawn. Also, 6. Bxb5 Qxd5 7. Nc3 Qxg2 8. Qf3 Qxf3 9.
Nxf3 Bd7 is OK for black. } 6... Nd4 { A new move ! The book line is 6... Qxd5 Nc3
7. Qd6 (7. Qc5?! leaves the queen too exposed). Black can also play 6... h6
which drops a pawn for active play. 6... h6 7. Nxf7 Kxf7 8. dxc6 Bc5 (Kirilov
- Shebenyuk, coor. 1985.) } 7. c3 Nxd5 8. Ne4 Qh4 { Black's pieces swarm around
white. Now if 9. d3 then 9... Bg4 10. Qd2 entombs many of white's pieces. } 9. Ng3 Bg4 10. f3 { How should black respond with two pieces hanging? Attack of
course! } 10... e4 11. cxd4 Bd6 { Black sacrifices material until it hurts. Play is
now razor sharp on the king side. } 12. Bxb5+ Kd8 13. O-O exf3 { White is a
piece up with no peace. How should white respond to black's threat of 14...
fxg2 attacking both white's Rook and Queen? The natural 14. gxf3 is refuted
by 14... Bxg3 15. hxg3 Qxg3+ 16. Kh1 Nf4 17. Qe2 (forced) Nxe2 winning. } 14. Rxf3 { This may be the losing move. After 14. Qe1!, black will find it hard to
justify his material sacrifice. } 14... Rb8 15. Be2 Bxf3 16. Bxf3 Qxd4+ 17. Kh1 Bxg3 18. hxg3 Rb6 19. d3 Ne3 20. Bxe3 Qxe3 21. Bg4 h5 22. Bh3 g5 23. Nd2 g4 24. Nc4 Qxg3 25. Nxb6 gxh3 26. Qf3 hxg2+ 27. Qxg2 Qxg2+ 28. Kxg2 cxb6 { Black's
attack has regained the lost material. Now it is only a matter of endgame
technique. } 29. Rf1 Ke7 30. Re1+ Kd6 31. Rf1 Rc8 32. Rxf7 Rc7 33. Rf2 Ke5 34. a4 Kd4 35. a5 Kxd3 36. Rf3+ Kc2 37. b4 b5 38. a6 Rc4 39. Rf7 Rxb4 40. Rb7 { Why you might ask did white stop short of capturing on a7? Indeed, 40. Rxa7
is better. No doubt that after white saw that the capture on a7 loses also,
he decided to complicate matters in the hope that black might go wrong. } ( 40. Rxa7 Rg4+ 41. Kf3 Ra4 42. Rb7 b4 43. a7 b3 44. Rc7+ Kb1 45. Kg3 b2 ) 40... Rg4+ 41. Kf3 b4 42. Rxa7 b3 { With this move white resigned. There is little use in
wasting postage on a lost game. The game might have continued: 43. Rb7 b2 44.
a7 Ra4 when black's b-pawn cannot be stopped. } 0-1
