I run old LCT II, BT2630 and BS2830 tests in Pentium4 2400 Mhz and 256 MB hash.
Maximum time
was 10 minutes for eachposition. (You can find test suites with Google). Results
for 3 top engines:

              Shredder 8      Fritz Bilbao    Gandalf 6

LCT II        30              32              32
(35 pos)

BT2630        29              28              29
(30 pos)

BS2830        20              20              18
(27 pos)

In LCT II is one dubious position:
[D]2k5/p7/Pp1p1b2/1P1P1p2/2P2P1p/3K3P/5B2/8 w - - bm c5

Also one dubious one in BT2630:
[D]2b1q3/p7/1p1p2kb/nPpN3p/P1P1P2P/6P1/5R1K/5Q2 w - - bm e5

In BS2830 is a lot incorrect looking positios like:
[D]2r1r3/p3bk1p/1pnqpppB/3n4/3P2Q1/PB3N2/1P3PPP/3RR1K1 w - - bm Rxe6
[D]rn2r1k1/pp3ppp/8/1qNp4/3BnQb1/5N2/PPP2PPP/2KR3R b - - bm Bh5
[D]r3k2r/pb3pp1/2p1qnnp/1pp1P3/Q1N4B/2PB1P2/P5PP/R4RK1 w kq - bm exf6
[D]r1b1qrk1/ppBnppb1/2n4p/1NN1P1p1/3p4/8/PPP1BPPP/R2Q1R1K w - - bm Ne6
[D]8/8/4b1p1/2Bp3p/5P1P/1pK1Pk2/8/8 b - - bm g5

Are there other errors may be?
