Two other things you might try that will normally give you the best results are to compile crafty as a single object (I belive in the Makefile.nt this is the craftyx option). This will allow the compiler to optimize it as one large object. The second item is for the Intel compiler and use the PGO option. To do this; 1. compile crafty with the additional options of "/prof_genx /prof_dir ." 2. run crafty with the following command "crafty < prof" Note the prof file is below. Make sure you have a normal crafty.rc, book file and EGTB path when you run this and in the same directory as the source as it will create a file that will be used in the second stage. 3. del crafty.exe crafty.o egtb.o 4. compile crafty with the additional options of "/prof_use /prof_dir ." -----Begin prof file---------------- st=10 ponder=off display nomoves setboard rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq move book off setboard rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq move setboard 1k1r4/pp1b1R2/3q2pp/4p3/2B5/4Q3/PPP2B2/2K5 b move setboard 3r1k2/4npp1/1ppr3p/p6P/P2PPPP1/1NR5/5K2/2R5 w move setboard 2q1rr1k/3bbnnp/p2p1pp1/2pPp3/PpP1P1P1/1P2BNNP/2BQ1PRK/7R b move setboard rnbqkb1r/p3pppp/1p6/2ppP3/3N4/2P5/PPP1QPPP/R1B1KB1R w KQkq move setboard r1b2rk1/2q1b1pp/p2ppn2/1p6/3QP3/1BN1B3/PPP3PP/R4RK1 w move setboard 2r3k1/pppR1pp1/4p3/4P1P1/5P2/1P4K1/P1P5/8 w move setboard 1nk1r1r1/pp2n1pp/4p3/q2pPp1N/b1pP1P2/B1P2R2/2P1B1PP/R2Q2K1 w move setboard 4b3/p3kp2/6p1/3pP2p/2pP1P2/4K1P1/P3N2P/8 w move setboard 2kr1bnr/pbpq4/2n1pp2/3p3p/3P1P1B/2N2N1Q/PPP3PP/2KR1B1R w move setboard 3rr1k1/pp3pp1/1qn2np1/8/3p4/PP1R1P2/2P1NQPP/R1B3K1 b move setboard 2r1nrk1/p2q1ppp/bp1p4/n1pPp3/P1P1P3/2PBB1N1/4QPPP/R4RK1 w move setboard r3r1k1/ppqb1ppp/8/4p1NQ/8/2P5/PP3PPP/R3R1K1 b move setboard r2q1rk1/4bppp/p2p4/2pP4/3pP3/3Q4/PP1B1PPP/R3R1K1 w move setboard rnb2r1k/pp2p2p/2pp2p1/q2P1p2/8/1Pb2NP1/PB2PPBP/R2Q1RK1 w move setboard 2r3k1/1p2q1pp/2b1pr2/p1pp4/6Q1/1P1PP1R1/P1PN2PP/5RK1 w move setboard r1bqkb1r/4npp1/p1p4p/1p1pP1B1/8/1B6/PPPN1PPP/R2Q1RK1 w kq move setboard r2q1rk1/1ppnbppp/p2p1nb1/3Pp3/2P1P1P1/2N2N1P/PPB1QP2/R1B2RK1 b move setboard r1bq1rk1/pp2ppbp/2np2p1/2n5/P3PP2/N1P2N2/1PB3PP/R1B1QRK1 b move setboard 3rr3/2pq2pk/p2p1pnp/8/2QBPP2/1P6/P5PP/4RRK1 b move setboard r4k2/pb2bp1r/1p1qp2p/3pNp2/3P1P2/2N3P1/PPP1Q2P/2KRR3 w move setboard 3rn2k/ppb2rpp/2ppqp2/5N2/2P1P3/1P5Q/PB3PPP/3RR1K1 w move setboard 2r2rk1/1bqnbpp1/1p1ppn1p/pP6/N1P1P3/P2B1N1P/1B2QPP1/R2R2K1 b move setboard r1bqk2r/pp2bppp/2p5/3pP3/P2Q1P2/2N1B3/1PP3PP/R4RK1 b kq move setboard r2qnrnk/p2b2b1/1p1p2pp/2pPpp2/1PP1P3/PRNBB3/3QNPPP/5RK1 w move setboard /k/3p/p2P1p/P2P1P///K/ w move setboard /k/rnn////5RBB/K/ w move quit -------End prof file-------------------- Bryan
