27/18 isn't exactly TAG.
I think pf I'd mix it up between 3betting and calling to bluff raise/float flops (obv folding is fine, but I don't suppose that's the question here). I suppose this depends on how much he plays back in 3bet pots or how often I'd been 3betting, also if his cbet % is huge I like calling to play at him on the flop a little more.
How many hands is this over? Cos the gap between vpip and pfr makes me think he calls too much and this may involve him calling lighter when 3bet, I might like to get a read on how he reacts first, making me a little more likely to call and play at him on the flop.
Flop, hmm. Again reads on how likely he is to bluff raise would help, like the fold cbet/raise cbet %. tbh I like a check. We obv don't fold out any better hands, and I think betting and then c/f turn kinda gives him too much scope to float us and take it away. It's a tough spot imo, but the risk of giving him a free card I don't think is as bad as the risk of him pushing us off the best hand later on. I think I like c/c on the flop and then evaluate the turn.
Turn is a c/f for me unless he's so aggro he loves to float flops and take it away on the turn, in which case a gambooooly crai could be good.
It's an interesting one though, I'm interested to hear what the "good" players (ie. not me

) make of it.
