How to reduce elo in Crafty 22.1 JA?

[bob]

Very good. This is interesting feature.I put it at skill 50. Makes
for a good game for players less than 1400 elo.

Thanks Robert,

Gerold.

P.S. Be good trainning for openings using large opening book.

Just to see what it takes to get Crafty down to the level of my favorite patsy:

Code: Select all

2 Crafty-22.1 JA (4%)   1220  161  128    15   80%  1000   27%
3 Chad's Chess V015     1000   91   90    41   50%  1035   22%
4 Crafty-22.1 JA (3%)    854  158  190    10   30%  1000   20%
6 Crafty-22.1 JA (2%)    644  218  468     6    8%  1000   17%

What are those numbers? 4% = skill 4?

Be interesting to see how this works out although ratingsj vs humans are different animals. One thing that is important is that this skill feature appears to be pretty well independent of hardware. Skill 70 reduces playing skill by 200 Elo no matter what the original hardware was to obtain the starting rating...

Sorry, I accidentally left off the header. Since skill goes up to 100 I shortened the description to a percentage, though I realize the Elo difference isn't going to be linear. I was just trying to show that Chad's Chess seems to play at a skill 3 to 4 level. I set Chad's chess to Elo 1000, so you can see very roughly the change in strength at low skill levels, even with the extremely small number of games.

If you still have the skill settings that make Crafty equivalent to your calibration engines I, and I'm sure others, would be interested in seeing them.
