SB checks, Hero ?

Check behind or push? Sb has 177 left, I cover. Comments on all streets obviously appreciated.

Your action is going to vary greatly depending on what type of player this is.

Unless you think AK is calling a push i'd check behind here. Villans river check is confusing, once you call the flop C/R I can't see why a set would bet so small on the turn. If his turn bet is for value surely he would value bet river with a Sets or KQ. Looks like KJ?
