The evals have a lot of similar things, but CB had more king safety as it was easier to discover what was attacking squares around the king... due to vector loads, compares, merges, etc... CB used null move, R=1, no recursion, Crafty uses null-move R=3...2, with recursion allowed. CB used singular extensions and a pretty complex selective search just prior to the quiescence search which also included checking moves and check evasion. The two programs are too different to compare, without running them against each other. Getting a T90 is difficult. To get a comparable multi-cpu alpha is also not easy. Which means a comparison is non-trivial.
