I did a very unscientific test and it did seem to just play legal moves. Not only that, if I did an illegal move it would tell me that I couldn't do it.

I think said that I wanted to play with new rules, where a queen could jump over any pawn, and it let me make that rule change -- and we played with this new rule. Unfortunately, I was trying to play in my head and I got mixed up and ended up losing my queen. Then I changed the rule one more time -- if you take the queen you lose -- so I won!
