Yup! No doubt about it, Crafty is a Romi killer, especially in the end game.
Hmmm, lets see, Crafty ~16 years of developement by more than one person (mostly Bob though) vs Romi of ~2 years devlopement by only me. Does this seem fair? Nope, but, who cares!

As a point of interest though, Romi in a Nunn2.pgn match was scoring about 38% against Crafty 19.19. However, the better Romi scored against Crafty the worse she scored against other engines. So, I stopped testing against Crafty. Awhile back (not too long ago) I did a test against Crafty 19.19 that I do not remember the results except for the fact that it was quite dissmal. Hundreds of ELO points gained against all engines as a whole and about 1/3 less points against Crafty!
Crafty's younger cousin, Faile (they seem to have a similar feel) was exactly the same. Better against faile, worse against Olithink, better against Olithink, worse against Faile. One time way back, Romi managed 41.5/50 vs Olithink and then only got 37.0/50 vs Faile. Before I started the improvement vs Olithink marathon it was 36.0/50 vs Olithink and 45.5 vs Faile. Unbelieveable!
Anyway Swami, I am sending NG5 to you, just in case that you would like to run that one against the gauntlet, as well. I really think, so far, that NG5 may be substantially stronger than NG4, but it is too early to tell.
Best,
Mike
