Why not bet turn? Since he overcalled his range should be a fair bit wider, including quite a few weak Axs. You can then x/b river.

bet turn x/b river imo

As played, operating under the assumption that BB flats all Axs and 3-bets AK, CREV tells me this is a +EV call assuming he bets AJ+ for value and bluffs all his GS+BDFD hands OTR, so KJs(2 combos), JT(2) and KT(3).

I think combos of AQ can also be pretty heavily discounted because he would squeeze to iso the fish a fair bit, right?

I have him betting something like this: 3h3c,3h3d,3c3d,Ah2h,As2s,Ah8h,Ah3h,AhJh,AhJc,AhJd,AsJh,AsJc,AsJd,JcTc,JdTd,KcTc,KdTd,KsTs,KdJd,KcJc.

Versus this range we have 50% equity so more than enough to call. If we give him all AQ combos we have 38%, so even then calling is +EV.

I like betting the turn as well. BB overcall is gonna be wide enough to justify vbetting here.

As played, easiest call in the world. There are some missed draws and he might even be vbetting worse.

+1 to bet turn, xb river. As played you have to call. He could easily be valuebetting worse.
