If he's calling wide to 3 bets then you can happily go ahead and make this part of your value 3 bet range expecting to dominate his continuing range a lot. It's not a huge deal though and calling here is defo good here too, and often better depending how he reacts to 3-bets.

As has been said shove the river vs Ax worse 2 pair and be happy about the easily more than 50% equity you have vs his calling range.
