tests of stockfish1.9.1 against new stockfish with a single core

Uri Blass · Post by **Uri Blass** » Thu Nov 27, 2025 3:34 am

I meant to give old stockfish 1000:1 time handicap but made a mistake.
I played 18+0.03 against 1800+30 and I need to play 1.8+0.03 against 1800+30 for that purpose.

In a previous test stockfish lost 1.5-0.5 with 600:1 time handicap (1 minute per move against 0.1 second per move and in these games new stockfish had more than 0.1 second per move because of my mistkae)

Stockfish dev promotes to rook expecting to sacrifice for the bishop, and black didn't take it! (Move 64.g8R. Do the logs show new stockfish expected immediate capture?) Note to neural net: do not under-promote unless you really need a knight.

While 1.8+0.03 against 1800+30 is 1:1000 time odds, 1956.3s / 4.0s = 489.1. So stockfish 1.91 used only about half of its time allotment. Time management has improved considerably.

Code: Select all

Match 1
# name                              games wins draws losses score elo  +   -

Match 2.
# name                              games wins draws losses score elo   +   -

Are you computing with BayesElo set with a prior of 8 drawn games? 75% score percentage is 191 Elo difference in a straight-up conversion.

Those early iterations (depths) in Stockfish have become so hollow over the years,
that such tests aren't very enlightening.

I expect new stockfish to beat all old engines with fixed depth.
If I am wrong show me one old engine that can beat latest stockfish at fixed depth of 10 plies even if you give it 15 plies.
