possible bluff at busted fd???

[teh_sponge]

PokerStars Game #12811246815: Hold'em No Limit ($0.10/$0.25) - 2007/10/24 - 00:09:34 (ET)

limited number of hands w/ villian but seems somewhat donkish and has been hitting alot of hands.

Does anyone prefer double barreling this turn???

I don't see villain playing 8x this way by smooth calling flop and giving a free card on this board.

Looks like a bluff at a busted fd to me
