not so bad to achieve a draw when you are 2 pieces down

according Vajolet Rxh6 is the best move (at depth 32)

I'm check in for the time out at the begining of my search and qs functions . I think it is sufficent ?

I think you should use the flag also for not updating tables, otherwise you fill it with wrong values. e.g. don't save results in transposition table after the timeout.

what is the speed difference between cpu and gpu training for those kind of neural network?

C is compiled while JS is interpreted?

Vajolet can be compiled for raspberry too.

There are duplicates in perft.txt, 6752 is the number of unique positions.

yes, they come from a sampling from a pgn file. so there are duplicates, but it does the work it's a good set to check perft

Tried to run the perft from elcabesa perft.txt, it failed on 27 out of 6752 positions on depth 1 and 2 only. Some positions where it failed. line: r3kb1r/p1p2ppp/2n4n/1p3bq1/P2pp1PP/1PN2P2/2PPP3/R1BQKBNR w KQkq -,26,1166,30119,1307169,34774744,1484852572, status: fail, depth: 2, nodes: 1141, data: ...

Not questioning you, just found that some other I found online must be wrong :) Like this one: r1k1r2q/p1ppp1pp/8/8/8/8/P1PPP1PP/R1K1R2Q w KQkq - 0 1 It says it should be 23 at depth 1 but I can clearly count that it should be 21 for both black and white... Makes me wonder about the others I found ...

Thank you elca! Are these confirmed to be correct?

I hope so, Vajolet and Stockfish indipendently give the same result on those positions, so I suppose they are confirmed. But I haven't tried counting all the moves using a chessboard
