I have an off-topic question if you don't mind. How do you get Delfi 5.4 to play at 1500 ELO? Do you have a version different from the free version? Thank you.

Maia Lichess 1546 has a blitz Lichess rating of around 1546 . This engine is run with maia-1100.pb.gz net at node 1 on a gauntlet test below. The Maia Lichess 1546 blitz rating has now changed. It is not 1546 anymore so the rating diff of 1500-Elo may now change. Blitz Rating history: https://i.img...

I am not sure if regression from 2019 is reliable.

I am not sure if lichess rating X of 2019 is the same as lichess rating X of 2021.

What is your proposal to make the estimates more closer to the truth?

You should try Cheese 2.2, I changed UCI_Elo calculation, based on a formula from one of your previous post. It's difficult to find a formula that works with all possible ELO values. In Cheese 2.2 there are 2 modes for UCI_Elo, in cheese.ini, UCILimitMode=0 to reduce the speed, or UCILimitMode=1 to...

Hello, I am trying to implement a simple algorithm to generate chess problems. It's pretty simple, I analyze lichess game with an engine and when there is a dramatic change in the evaluation, it means something is happening. However, I can't figure out a reliable way to determine the difficulty of ...
