3x is just a standard raise though. He might have wanted to isolate with the window licker knowing he would call. I think he would also do this with TT and maybe even 99 if he thinks seat 3 will fold, and he might also be worried about his limp UTG. I dunno, I'd certainly be raising in Seat 4's position with TT, wouldn't you? 99 sometimes, even 88 would be a borderline raise occasionally. Plus of course AK and maybe AQ as well.

Besides if you do push he has to be really worried about what YOUR hand is.. if he is doing this with 99+,AQ+ he will probably fold all bar QQ+,AK+ again like before.. but the difference this time is the overlay is much bigger, and you don't have to worry about overcalls, as there's just the BB to act.
