30/60 10 handed party

no stats on the button or bb, sb is a tag, but overly agressive...

folded around to me, I raise w/ A5s on the co, only bb calls

flop is 55K, he checks, I bet, he calls...

turn is A.... anyone check here?..... I have no stats on him, hasn't done anything out of line one way or the other in the 2 orbits I've been sitting w/ him
