Using: http://p4wn.sourceforge.net/src/index.html?start=r2k3B/ppp2p1p/7n/3p4/8/1P3N2/P4qP1/4RRK1%20w%20q%20-%200%2017&player=white

and setting the computer level to slowest, after 17. Rxf2 the computer responds with 17...Ng4 but the Knight from h6 is still left in the original position, and two black Knights appear on the board.

Right. It looks as if the display code is confused, but the engine has a correct view of the game -- that extra knight can't move, and if something "captures" it, the move is not read as a capture.

dusadrian commented 9 years ago

One other common denominator for all (latest) three issues is that computer level is set to slowest (level 6). Either that, or the way FENs are interpreted and/or constructed, might have something to do with the errors.

I think #16, #17 and this are avoided in the master branch. Adrian, if you find otherwise please reopen. Thanks.

Just retested the issue, it's solved for good. Awesome job, thank you!
