In the engine parameters, you can change a few things like outlook and contempt. Changing outlook to Ultra Optimistic and entering a high value for Contempt should make Ryke play more aggressively, avoiding draws at almost any cost. This does not mean that she will play better though. It is safe to assume that the standard settings are the best for overall performance. You might just get games that are more fun to watch with less draws.

You can´t do much about this on the current version, but we are talking about making this possible in version 3.0, either with options or with a separate version.
