[Spook]

I was hoping to check raise the flop (obvoiusly).
Is the pot big enough that a small bet will scare anyone off, and conversly is the pot big enough that I have to try to win it without a free card.

Can I fold to a turn cap? Or do I have to call it down. Villian is loose and agressive postflop.

edit: i hope that a player with top pair will bet out to protect.
