While watching Kasparov-Fritz tonight, I recognized, that the first capture was rather late in the game (at move 29). I wondered, how often such late first captures happen. I wrote a little routine to search PGN files for late captures. I used the games, I downloaded from Dann Corbit's ftp (those a00 - e99 files - over 3 million of games). There are a bit over 1000 games where the first capture happens only after the 30th move. The "winner" is this game: [Event "ICC 1 0 09/28/97"] [Site "Internet Chess Club"] [Date "????.??.??"] [Round "?"] [White "crafty"] [Black "humanoid"] [Result "1/2-1/2"] [ECO "A40n"] [Variation "Queen's Pawn: 1...e6 2.c4"] [Annotator ""] [Source ""] [Remark ""] 1. d4 e6 2. c4 d6 3.

In a 1 0 (one minute sudden death) ICC game, humanoid made 257 moves!? BTW, I clicked through the game very fast (hitting cursor right several times per second). While doing this, I did not see a really big score (>2) until move 223. I also tried some 2600.pgn file from Dann's ftp - which should only contain games between players with 2600+ Elo. From that file (it is a few years old, 23001 games) the winner is: [Event "Sarajevo"] [Site "Sarajevo BIH"] [Date "1982.03.??"] [Round "?"] [White "Sax, Gyula"] [Black "Beliavsky, Alexander G"] [Result "0-1"] [WhiteElo "2610"] [BlackElo "2655"] [ECO "C55"] [PlyCount "82"] [EventDate "1982.??.??"] 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.d3 Be7 5.O-O O-O 6.Bb3 d6 7.c3 Na5 8.Bc2 c5 9.Re1 Nc6 10.h3 Qc7 11.Nbd2 Be6 12.Bb3 h6 13.Nc4 Rad8 14.Qe2 Rfe8 15.Ne3 d5 16.Nf1 Bf8 17.Ba4 Bd6 18.Ng3 a6 19.Nh4 b5 20.Bc2 Bf8 21.Nhf5 Kh8 22.Qf3 Ng8 23.Ne3 Nge7 24.Ng4 d4 25.Nh5 Ng8 26.Qg3 f6 27.Qf3 Qf7 28.Ng3 g6 29.a3 Rc8 30.Ne2 f5 31.Nh2 f4 32.cxd4 cxd4 33.Bd1 g5 34.Bd2 a5 35.g3 Bd6 36.gxf4 gxf4 37.Kh1 Nf6 38.Ng4 Nxg4 39.hxg4 Rg8 40.Qh3 Rg7 41.Ng1 Rcg8 0-1 First capture was at move 32.
