Here are a few examples of nice moves made by Tiger. Perhaps other programs make these moves also. 1. Of course in this example white can play anything and win but Tiger chooses Qxf7. Here Tiger readily enters an endgame with the move Qxf7. This is exactly how any strong human would play. Most programs would most likely move the Queen. It is for me at least, an indicator that something unique is going on with Tiger's endgame eval. If it plays a move like Qxf7 maybe it knows something about liquidating into completely won endgames. 8/p2k1r2/1p2bQ2/3p4/8/1P4P1/1PP2R1P/6K1 w - - id Chess Tiger - Goldbar; bm f6f7; 2. This game illustrates an excellent liquidation into a won endgame. Noteworthy are the two rook captures on f6. The move Bh3 is one of the nicest examples I've seen of a program swapping down into an easily won endgame. Here are the three moves and the entire game. 1rb2rk1/p1q2ppp/2nb1n2/2p1p3/4P3/1PNPN1P1/1BPQ2BP/R4RK1 w - - id Chess Tiger 12.0 K6 - Nimzo '99 P200MMX; bm f1f6; 1r1q1rk1/p3bp1p/2n1bp1Q/2pNp3/4P3/1PNP2P1/1BP3BP/5RK1 w - - id Chess Tiger 12.0 K6 - Nimzo '99 P200MMX; bm f1f6; 2r2rk1/p2qbp1p/2n1bR1Q/1NpNp3/4P3/1P1P2P1/1BP3BP/6K1 w - - id Chess Tiger 12.0 K6 - Nimzo '99 P200MMX; bm g2h3; [Event "SSDF Game 40/2"] [Site "Hans C."] [Date "1999.11.07"] [Round "22"] [White "Chess Tiger 12.0 K6450"] [Black "Nimzo '99 P200MMX"] [Result "1-0"] [WhiteElo "?"] [BlackElo "?"] [ECO "B24"] 1. e4 c5 2.

A nice move exploiting some of black's kingside weaknesses. 1rb1r1k1/pp3p1p/2np2p1/q1p5/3bPB2/2NP1BP1/PPPQ1R1P/5RK1 w - - id Chess Tiger 12.0 K6 - Nimzo '99 P200MMX; bm f4d6; 4. Nxc5 leads to active piece play for white. The next few moves went 1 ... Nxf1 2. Kxf1 Bc8 and black's position is extremely cramped. Whether or not Nxc5 is the best move is debatable(black's move Bc8 may not be the best defense)but it appears to reveal an awareness of how the relative value of pieces change depending on position. r2q1rk1/pp1b1pbp/2n1p1p1/2p1P3/P2pNP2/1P1PnNP1/2PQ2BP/R1B2RK1 w - - id Chess Tiger 12.0 do - Shredder 2 P200MMX ; bm e4c5;
