Do people have a preference for either player at the various sizes?
I'm currently much prefering p2 at 5x5. But I think that's because I like to make messy grids with lots of small potential features in them, therefore aiming for 3 long chains.
Doesn't really matter to me, since I always win. Tho facing a first player is much more rewarding as I not only play perfectly but also cause my opponent's mistake.
