Stockfish and Dragon time odds matches Empty
PostSubject: Stockfish and Dragon time odds matches   Stockfish and Dragon time odds matches EmptyTue Oct 05, 2021 4:54 pm

A couple of years ago I did a fun research how much time odds lower rated engines needed to beat Stockfish 11, see : http://rebel13.nl/rebel13/stockfish-handicap-matches.html

This time we do it different, we pitch SF14 vs sf14 in 3 steps:

Match-1 : SF14 (40/40) vs SF14 (40/80) - one-vs-two-seconds
Match-2 : SF14 (40/40) vs SF14 (40/160) - one-vs-four-seconds
Match-3 : SF14 (40/40) vs SF14 (40/320) - one-vs-eight-seconds
Match-4 : SF14 (40/40) vs SF14 (40/640) - one-vs-sixteen-seconds

And measure the elo gain.

We do the same with Komodo Dragon 2.5
