Looks really complicated, with the reference site not even working properly.

Alternative: install Droidfish from the Fdroid store and use engines as executables like before. Problem solved.
This is working fine indeed, but is droidfish handling tourney or just engine versus human ?

Re: Winter

I don't want to spam forum with every little patch, but version 0.9.5 adds support for Fischer Random / Chess960, which feels like a feature some people care about. Awesome, just when I started my FRC "Top 20" tournament. Will include Winter in it when you finally release it (waiting also for Minic...

Re: Calculation the playing strength of a move

A Patzer might not be able to beat Stockfish even when given Queen odds; he will have no problem to covert KQK, though. This remark makes me try to play SF with Q odds on lichess, and it seems to me, SF really didn't play well, it proposed exchanges all game long... I'm only 1600 on lichess, opened...

static null move pruning margin

Have you ever consider using a negative (little !) margin for static null move pruning at depth 1 ? We often seek for parameters in a formula like this one if ( staticScore > beta + depth * slope + offset ) return staticScore And often "offset" is 0 and is omitted and coeff is something around 100cp...

Re: uci question, receive stop before pondering starts

UCI says: * stop stop calculating as soon as possible, don't forget the "bestmove" and possibly the "ponder" token when finishing the search So, you don't have to stop immediately. You can complete the first iteration and return the best move. That's what I do. That seems like a good advice ! It se...

Re: uci question, receive stop before pondering starts

At least it works.

So I conclude that, even when engine is pondering, GUI are expecting a "bestmove" line even if there is no best move.

This looks fair anyway. My bad.
