fold pre because the presence of AK in his range means we wont have odds to mine (plus sometimes we get ATx and no action from KK or QQ, and we very occasionally get set-over-setted on TKx and TAx). as played i'm pretty comfortable folding river. there are still 10 combos of AA/KK/AK and i'm pretty sure his range hasnt been much wider than that since his first action.
