Hi all,
yesterday during a tournament between Weini and Horizon, a game led to this critical position which seems (stockfish says) to be a draw
[d]1k6/1pr3bR/p5P1/4pp1P/1P1pPp2/3N1Pq1/8/3Q1K2 w - - 0 88
Weini didn't find the draw and lost the game badly, here is the full game

Do you have any idea how this draw can be found. I think that because of the presence of queens and rooks the game phase is still concidered *not* an end-game and that LMR is thus still aggressive. A way to discourage LMR is such case is probably to check that score is not going down too badly. How do you check that in your engines? Do you have access to "previousBestScore" everywhere and apply LMR only if the score is not falling to much ?

Re: Hard draw, LMR question
Stockfish has a lot of code to adjust LMR based on various factors and one of them is the score differential, as you suggest.
I'd start by looking at how they do it.
I have personally not had success adding this kind of adjustment, but you can try it.

Re: Hard draw, LMR question
hello
May be you can check your 3reps (three fold repetition) if it works correctly ?
My engine Isa find a draw possibility at depth 11 :

Re: Hard draw, LMR question
Thank you for those figures. Weini find the draw (score 5 is contemp) at depth 17 only with current setting (probably too much LMR...), and this depth was not accessible at the playing TC. Maybe contempt is not working as I thought but I'll check 3reps anyway. Here is a full log by the way ... :
