Pot is quite bloated and we don't really have a strong hand way 3-way OOP. I would start by checking the flop, or if I were to bet I'd make it around 11bb. No need to make it half pot given how big the pot is already, if someone shoves I think we have to fold and invested too much money that we didn't have too.

Turn is fine I would be giving up too.

I think we have to call the turn as we block AK and villain should not really be betting much here at all. We also have outs to the nuts and block top set.

I think checking the flop is an option. If you bet then don't be afraid to look weak by making it less than half pot. If he has showdown value he's unlikely to turn his hand into a bluff just yet.

On the turn as played, I think with top pair, and the draw you're getting almost direct pot odds to continue with, you can call. His small bet can be a protection bet hoping you go away. If he has KJ or AT then he'll likely check behind on the river. If the turn bet was any bigger I would fold also.

Don't squeeze. The opener is not folding and after he calls the other guy isnt either. Call pre play a moderate pot rather than bloating it pre out of position against two players, hoping to continue into two opponents with a made hand or by some miracle they both fold to a cbet.

KQ dominates a lot of the openers range so win monies from his Kx Qx hands and break him with straights.
