If you don't know the exact details your comparisation is going
nowhere.

The SE is a nice example of this. The SE that Vincent tested is
totally unlike what DB used. It's tuned for a chessprogram like
crafty, not DB.

I have one that is closer to DB, but Vincent didn't test that of
course. Also, depiste all publications MANY of the details are
totally unsure. SE is VERY complex. And you're not ever going
to get something close to what DB did because they simply left
out way too much details.

I am telling you now that you are never going to get this
comparisation to work. Not unless Hsu fills in the missing
details.

Hello? How can you know this? The better your eval is the
more pruning is going to hurt.
