Re: Poor mans testing process please

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...

Re: Skippers memorable game(s) (not)

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...

Skippers memorable game(s) (not)

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. [Event "Computer Chess Game"] [Site "LAPTOP-1FK7MTIP"] [Date "2020.03.18"] [Round "-"] [White "Skipper"] [Black "Fairy-Max 4.8V"] [Result "1-0"] [TimeControl ...

Re: What's new 2020 ?

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.

What's new 2020 ?

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

Re: Goofy 2

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...

Re: Goofy 2

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.
