[disjunction]

You don't give a preflop read. I think that the turn c/r and the river call go hand-in-hand, you think AK and AQ are a significant part of his range. The only way to c/r the turn and not call the river are if lots of hands with 2-4 (A2, 22, etc) are part of his range, no?

But if his range is fairly large preflop, as it should be, and isn't likely to contain 2-4, I don't think I like the turn c/r on this board. Given the turn c/r, I fold unless he is too tight preflop.
