Hi all, I have pretty much no facilities for testing changes in my program for gains or loses. What is the best compromise that will get me in the ball park? I can, and have a lot of stats, but is there a most logical/reliable way to determine if a change is a plus or a minus ? Time to depth ? Node...

Had to do with this code. As expected. Looks like this code works if (TimeManagement.SearchExpired(Level, TimeControl)) { if (plyCount == 0 && IDMoveProcessed ) // IDMove is move from previous iteration and searched through { // already a move found at top level and at least as good as move from pre...

Don't know where to post this but almost ages ago when Skipper won from Fairy-max. Ouch missed a mate in 1 move 79. So too many bugs I guess.

Greetings from Sam the Eagle

Only have to skip some more irrelevant moves.
Only have to select a move from a list of legal moves which at least does not worsen a position.

So it should not be difficult.

Did I miss something or are there no new inventions after LMR and (convolutional) neural networks ?

No disabling SEE in QSearch harms performance. It takes Skipper already at least twenty seconds to find a move at level 1 in position below: [d]r4rk1/p1q1ppb1/1p4p1/2Np1b1p/1n1P2n1/6P1/PPP1BP1P/R1BQNRK1 w - - 0 15 6 -18 2797 5840580 c5a6 b4a6 e2a6 c7d8 a6b7 a8b8 5 -22 2628 5568258 c5d3 b4d3 e2d3 f5d...

Wait. 4 seconds now. I had to disable SEE pruning in QSearch. Don't know yet if that harms/improves overall performance.

Takes 30 seconds for Skipper to find Bd3 in this position. That is too much when playing blitz games.
