NL25 - I am lost on all four streets, deep

[AAmucked]

Hero 39.35
Jbis covers

Six handed on FTP, villain Jbis limps UTG. Villain had been relatively tight and this might've been the first time he limped at the table. And UTG for sure. I've been here for a bit and he's been playing pretty tight. This set off alarm bells.

CO calls and SB calls and I am unfortunately dealt A /images/graemlins/spade.gif Q /images/graemlins/spade.gif in the BB, and don't want to be a super-nit so I raise to 1.75. Just jbis calls.

Flop J /images/graemlins/spade.gif A /images/graemlins/heart.gif 2 /images/graemlins/heart.gif

I bet 3.25. This makes it less likely he has AA and KK just got outflopped. He calls.

Turn 3 /images/graemlins/spade.gif

I'm still worried. What is he playing like this? If he has KK I figure I can't get any value and weaker aces fold. I check. He checks behind.

River 10 /images/graemlins/diamond.gif

I retardedly bet 6.5 into 10 as a quasi blocker. He raises to 16.5. Hero ..?

I thought maybe KQhh, A10, 22 but not to sure villain was capable of a bluff because he's being pretty tight. WTF is he playing like this?

i would never check that turn. bet/ and call or fold to a push but dont check it. If he just calls again bet the river and if he pushes fold. As played i would fold to his raise.

Raise more preflop, fold river.
