Brilliant! Makes a simple children's game very interesting. One aspect I really enjoy is that it makes clear the knee-jerk response towards action bias[0]. There are times when your opponent has two-in-a-row, but the probability of a frown on the third is > 50%, in which case it's in my interest to have my opponent click on the third square instead of me (but even knowing that cognitively, it's still hard to not action).
