Who's Trapping Who?

[MeanGreenTT]

PS $3r to 500k, no read on vilian as he was moved to table last hand. Just into level 6, so there's a LONG way to go. I'm behind average by a couple of thousand and behind to most of the table.

PokerStars No-Limit Hold'em Tourney, Big Blind is t200 (8 handed) internettexasholdem.com

Hero (t7900)
MP1 (t12930)
MP2 (t19680)
CO (t2545)
Button (t15995)
SB (t9415)
BB (t12150)
UTG (t12500)

Preflop: Hero is UTG+1 with J[img]/images/graemlins/diamond.gif[/img], J[img]/images/graemlins/spade.gif[/img].
<font color="#666666">1 fold</font>, <font color="#CC3333">Hero raises to t600</font>, <font color="#666666">5 folds</font>, BB calls t400.

Flop: (t1300) 9[img]/images/graemlins/diamond.gif[/img], 4[img]/images/graemlins/spade.gif[/img], 7[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(2 players)</font>
BB checks, Hero checks.

ok, I know this is an extremely unconventional line, but I feel this was a good spot for a trap heads-up. Vilians range is rather large, the board isn't that scary heads-up and if he buys into it, my play looks like an AK whiff weak-tight check. I might be able to take down a bit nicer pot with a raise on the Turn.

Turn: (t1300) 4[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">BB bets t600</font>, <font color="#CC3333">Hero raises to t1800</font>, BB calls t1200.

I get exactly what I want but he doesn't seem to be playing along with my plan....

River: (t4900) 6[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(2 players)</font>
BB checks.

Hero???

ok, there's T4900 in the middle and I've got T5500 behind. I could still have the best hand but if not...I increse my stack by 50% if I take it down, is this a WAWB situation? Does betting here really gain me anything? Check behind and hope for the best?

Comments on all streets appreciated, flamesuit on, Thanks!
