LamChop at 5sec move on P133 and it only got 2/24 correct! Guess I'll give it a longer run. Where are these positions from? Specifically, which positions (if any) are in other test suites? I like to know when a suite contains positions that I already use for testing. > >4Q3/6pk/2pq4/3p4/1p1P3p/1P1K1P2/1PP3P1/8 b - - bm Qg6; >8/5pk1/4p3/7Q/8/3q4/KP6/8 b - - bm Qd5; >r3bb2/P1q3k1/Q2p3p/2pPp1pP/2B1P3/2B5/6P1/R5K1 w - - bm Bxe5; >r1b5/p2k1r1p/3P2pP/1ppR4/2P2p2/2P5/P1B4P/4R1K1 w - - bm Bxg6; >6r1/1p3k2/pPp4R/K1P1p1p1/1P2Pp1p/5P1P/6P1/8 w - - bm Rxc6; >1k2b3/4bpp1/p2pp1P1/1p3P2/2q1P3/4B3/PPPQN2r/1K1R4 w - - bm f6; >2kr3r/ppp1qpp1/2p5/2b2b2/2P1pPP1/1P2P1p1/PBQPB3/RN2K1R1 b Q - bm Rh1; >6k1/2q3p1/1n2Pp1p/pBp2P2/Pp2P3/1P1Q1KP1/8/8 w - - bm e5; >5r2/pp1RRrk1/4Qq1p/1PP3p1/8/4B3/1b3P1P/6K1 w - - bm Rxf7 Qxf7; >6k1/1q2rpp1/p6p/P7/1PB1n3/5Q2/6PP/5R1K w - - bm b5; >3r2k1/p6p/b2r2p1/2qPQp2/2P2P2/8/6BP/R4R1K w - - bm Rxa6; >8/6Bp/6p1/2k1p3/4PPP1/1pb4P/8/2K5 b - - bm b2; >2r1rbk1/p1Bq1ppp/Ppn1b3/1Npp4/B7/3P2Q1/1PP2PPP/R4RK1 w - - bm Nxa7; >r4rk1/ppq3pp/2p1Pn2/4p1Q1/8/2N5/PP4PP/2KR1R2 w - - bm Rxf6; >6k1/p4pp1/Pp2r3/1QPq3p/8/6P1/2P2P1P/1R4K1 w - - bm cxb6; >8/2k5/2p5/2pb2K1/pp4P1/1P1R4/P7/8 b - - bm Bxb3; >2r5/1r5k/1P3p2/PR2pP1p/4P2p/2p1BP2/1p2n3/4R2K b - - bm Nd4; >8/1R2P3/6k1/3B4/2P2P2/1p2r3/1Kb4p/8 w - - bm Be6; >1q1r3k/3P1pp1/ppBR1n1p/4Q2P/P4P2/8/5PK1/8 w - - bm Rxf6; >6k1/5pp1/pb1r3p/8/2q1P3/1p3N1P/1P3PP1/2R1Q1K1 b - - bm Qc2; >8/Bpk5/8/P2K4/8/8/8/8 w - - bm Kd4; >1r6/5k2/p4p1K/5R2/7P/8/6P1/8 w - - bm Kh7; >8/6k1/p4p2/P3q2p/7P/5Q2/5PK1/8 w - - bm Qg3; >8/8/6p1/3Pkp2/4P3/2K5/6P1/n7 w - - bm d6;
