20/40 hand

[KINGOFINLAND]

4 handed. Me=$4k Button=$2k BB=$11k
I raise utg to $160 with K [img]/images/graemlins/spade.gif[/img] Q [img]/images/graemlins/club.gif[/img] those guys call.
Flop is 8 [img]/images/graemlins/heart.gif[/img] K [img]/images/graemlins/diamond.gif[/img] 7 [img]/images/graemlins/diamond.gif[/img] I bet $480 both call.
Turn T [img]/images/graemlins/heart.gif[/img] what now

I don't have that good reads, but I believ both would raise flop with very good, AK is possible - and im NOT sure if they will fold those if I bet big.
I just entered the table and haven't been in any big pots, BB bluffed me out from biggish pot couple hands ago and showed T9, which he had called my reraise out of position...
