Opponent is a smart semi-tight player, a TAG with tricks. 27/22/2.8 (VPIP/PFR/AF) over ~980 hands. I've been playing a similar yet slightly tighter style than him.
Villain's a good player so I know his pre-flop range is very wide here. Thus, I can assume that I'll often flop good equity with this hand and It's likely I have card-advantage in this situation vs this opponent. Generally, as we are deep there is a fair amount of room for manoeuvre here.

"semi-tight...TAG". It's subjective of course but that's the terminology I use to differentiate the in-betweeners. – Toby Booth♦ Feb 2 '12 at 20:04
