Hi. The problem:
AI level - Stockfish level
1 1500
2 1470
3 1542
4 1792
The ratings for levels 2-8 are determined by its wins and losses. People have been thrashing level 2 a bit more than level 3 as of late, hence those numbers. You'll see that the ratings change over time.
More information here:
http://en.lichess.org/blog/U4mtoEQAAEEAgZRL/strongest-chess-player-everOk - it's little data based rating. So, in the code, level 2 is more difficult than level 1, ok?
Thanks.

Yes, it is. Like it says in the blog post I linked to above:
AI level 1: skill 3/20, depth 1, 50ms
AI level 2: skill 6/20, depth 2, 100ms
AI level 3: skill 9/20, depth 3, 150ms
AI level 4: skill 11/20, depth 4, 200ms
AI level 5: skill 14/20, depth 6, 250ms
AI level 6: skill 17/20, depth 8, 300ms
AI level 7: skill 20/20, depth 10, 350ms
AI level 8: skill 20/20, depth 12, 400ms
Thanks a lot!
In the future, could I send e-mail to you to talk about this (skill and depth in chess960)?
