Flopped top 2 after being CRed preflop

[CLB]

Villian in this hand (UTG+1) hasn't done anything particularly out of line since I've been at the table, although I'm multi-tabling and may have missed a move or two. It's the first time I've played with him. I've been PF raising more than usual - probably around 15+% or so - because the table is so tight, and if he's paying attention I should seem taggish. We've tangled a few times recently. I took a decent pot away from him by CR AI on the turn in one case and I took another one away from him with a good sized raise on the turn. I've also checked down a few hands with him to keep from looking like too much of a maniac. Then this hand came along...

<font color="black"> This feels like raise or fold to me. If I call here what do I do if he fires a PSB on the turn?</font>
