Wouldn't a match with an open-source engine be unfair? The competing close-source engine could embed the opponents source inside it to predict the exact moves that the opponent would make, thus gaining a speed advantage.

Even more interestingly, what would a match between two open-source engines look like, if they both embedded each other?

Eliezer Yudkowsky gave a talk at MIT recently that touched on this very subject:

There's a fair bit of data (opening books) and configuration that can differ between two otherwise equivalent engines.
