I just got deep Rybka and I'm wondering what options/boxes I can check, or what I can change in the configuration of the engine to make this program unbeatble, or as close to it as possible. Also i don't really get what hash size and ready time out is when you configure the engine. Does this have an impact on how the engine performs? with the drop down menu type it says "universal chess interface" what does that mean and does it make a difference what's in that box? Sorry for asking a million questions i'm just trying to get into this program and make it as hard to beat as possible. Thanks!
