Hello Tom,
Was playing a tournament in Winboard with Djinn and 7 other engines when this game occoured:
[Event "Computer chess game"]
[Site "CHESS-COMPUTER"]
[Date "2004.07.23"]
[Round "2"]
[White "Hermann 1.1.6"]
[Black "Djinn 0.870"]
[Result "*"]
[TimeControl "60"]
1. Nf3 d5 2. g3 Nf6 3. Bg2 Bf5 4. Nh4 Bg4 5. d4 e6 6. O-O c5 7. c4 cxd4 8.
cxd5 exd5 9. Qxd4 Nc6 10. Qd3 Qc7 11. Bg5 Nb4 12. Qc3 Qb6 13. Bxf6 gxf6 14.
Qd2 Rc8 15. Nc3 d4 16. Na4 Qd6 17. a3 Nc6 18. Rfc1 Qe5 19. Nf3 Qb5 20. Qd1
Rd8 21. h3 Be6 22. Nd2 d3 23. exd3 Qxd3 24. Ne4 Be7 25. Qxd3 Rxd3 26. Nac5
Rd4 27. Nxb7 Nd8 28. Nxd8 Bxd8 29. Rd1 Rxd1+ 30. Rxd1 O-O 31. b4 Be7 32. f4
Rc8 33. Rd3 Rc1+ 34. Kf2 Bf5 35. Rc3 Ra1 36. Nd2 Be6 37. g4 f5 38. g5 a5
39. b5 Rxa3 40. Rxa3 Bxa3 41. h4 Bc5+ 42. Kg3 a4 43. Nb1 a3 44. Nxa3 Bxa3
45. b6 f6 46. Bc6 fxg5 47. fxg5 Bc5 48. b7 Ba7 49. Kf4 Bb8+ 50. Ke3 Kf7 51.
h5 Ke7 52. Bh1 Kd6 53. Kf4 Kc5+ 54. Ke3 Bc4 55. g6 f4+ 56. Kf2 hxg6 57.
hxg6 Kd4 58. Bc6 Bd3 59. g7 Bc4 60. Bb5
*
Djinn sent the move 60...Bg8 but in Winboard the move came out as Bf5? Not even sure if its a bug by Djinn. I have the games log file saved if you want to have a gander at it. Drop me an e-mail.

Thanks Luis,
I'll send you an email this evening. It looks to be an interesting bug. I've
never seen Winboard change the move, but you never know.
regards,
