i'd need to write a C interface for it, then try to maintain compatibility through new releases. (AKA i'd effectively end up rewriting it). it might seem like less of a burden for me to just write my code in C++, but i guess i'm just a caveman who is stuck in his old ways and would rather reinvent the wheel than switch language horses just to save some effort.

The bias that Peter Drake talks about is negligible and doesn't have a noticeable impact on playout results. (and uniformity of playout isn't something to fight for in MC Go) Jason, can You tell me why You don't want to use libego instead? Actually this is open question to all comp-go readers. Is libego too complicated? Do You have problems with compilation? Or You are not comfortable with the GNU license? Any other reason?
