HU: chipleader Kc 7c What's your move?

[Oluwafemi]

blinds 100/200

if villian has been paying enough attention, he should know that i've been playing tight-aggressive poker- i've definitely been paying attention to him. villian likes to limp in on the SB with any kind of hand and my plan was to bluff raise my BB to keep him honest. the last couple of hands i have just checked to the flop with mostly BS.

hero 7805 after posting 200 (K [img]/images/graemlins/club.gif[/img]7 [img]/images/graemlins/club.gif[/img])
villian 5295 after limping extra 100 in SB (hand: ?)

i raise to 600 and villian calls.

flop comes: 2 [img]/images/graemlins/club.gif[/img]10 [img]/images/graemlins/club.gif[/img]8 [img]/images/graemlins/heart.gif[/img]

i check.

villian bets all-in 4895.
