Subject: Question regarding perft

Author: E. Nielsen

Hi,

We have got this little strange 'challenge' with our move-generator... ;-)

There is this one perft-test from
http://homepages.caverock.net.nz/~peter/perft.htm
that fails from depth 3.

r3k2r/p1ppqpb1/bn2pnp1/3PN3/1p2P3/2N2Q1p/PPPBBPPP/R3K2R w KQkq -

We get:
perft 1
Total moves=48             [ok]
perft 2
Total moves=2039           [ok]
perft 3
Total moves=97898          [should be 97862 i.e 36 positions less]
perft 4
Total moves=4087387        [should be 4085603 i.e 1784 positions less]


Is there anybody who has any idea on where such an error could originate?


Thanks in advance
Eyðun Nielsen
