Raise it up to $77-$80. This forces SB to call $55-$58 of the $120 he has left to win over $180. He'll shove a set and a lot of overpairs, maybe even a big heart draw. It gives him great implied odds, but if he pairs the river, he'll have issues laying it down getting ~ 3:1 on a riverpush- same goes for if he chose to call with 88-TT.

With a read that SB had an overpair I don't like a push, make a pot commiting raise to about 70-80 this way money will go in on the river.
