£50 B&M SB/BB Hand

[Ranners]

Bit of background info - I've played with villain in the Mirage during the 2006 WSOP ($100ish tournament), but I'm 99% certain he has no idea who I am (I confirmed this after the tourney). I never played enough hands to get any kind of read though. It's quite odd that the next time I play with him is a year later, especially as I play at this venue quite a bit.

Blinds are 600/1200. 20 minute clock, this level has just started. Hand before he calls an all in for 1/3 his stack with J9s because sb has pushed 3 times on his bb. He beats K4o. He seemed annoyed that someone was trying to 'take the piss'.

17 left - 6 paid - Avg stack is 13k (crapshoot time)

Hero has 23.5k
Villain has 23k

Dealt to hero Ac9c

All fold to sb
Villain completes
Hero raises to 4200
Villain calls (after a dwell)
(At this point I make him for ATC)
Flop 974 rainbow
Villain checks
Hero bets 4k (I want a check raise here)
Villain calls
Turn 5 (completes rainbow board)
Villain bets all in (circa 15k)
Hero ????

I'm interested in the view of each street here. I think my flop bet is poor, I expect a check raise judging on his past behaviour, but when that doesn't come, pretty much any card on the turn kills my hand.
Almost all the players in this tournament are quite poor and weak-tight, but I'm giving villain a bit more credit because I've seen him in Vegas.

-Edit-
*apologies for the format - I know it's not that easy to read. Not sure on the best way to post live hands.
