Villain seems to be a straightforward nit and is running 10/6 with a 3% 3Bet over 300 hands.
I 4B for value + I'll be OOP + if I just call I'd invite the original opener and I don't want to play this hand OOP vs 2 players.

Since this guy is a nit I have his range at QQ+ AKs,AKo (mebbe JJ)

I'm just wondering about the right flop line here. I think if I bet anything more than 1/2 pot he'll just fold hi JJ, QQ, KK hands and obv continue with AA, AK. But why would I want to fold out JJ or QQ? I think if I check he'll play the hand pretty straightforward and I can comfortabley fold to any action, as I don't expect him to be betting JJ, QQ, KK here very often. I was thinking about betting small like 1/4 to 1/3 pot to keep his high pairs interested, but then I thought I'd be put into some tough turn spots with a lot of $$$ in the pot as he'll likely just call with his whole range.

So thoughts on flop line are needed thanks:
