yahoo is 5x5 and “play whoever else is online” but if you find someone else who wants to, you can play 6x6 on a 10x10 grid. I've done this before (I am wccanard there too—look out for me). jijbent.nl and yourturnmyturn.com are turn-based and 6x6. jijbent is in Dutch but ytmt is " a translation of jijbent” so you can play ay ytmt for a while and then start at jijbent. jijbent is as good as here, if not better, in terms of really top quality players.
