Ill advised river bluff?

[sfer]

SB is a calling station and BB is unremarkable. BB coming alive on the river tells me he got there but I thought I could get a small spade to fold because my prior actions could look like I have the K [img]/images/graemlins/spade.gif[/img]. Obviously I fold if reraised. I have a feeling I'm gonna get raked over the coals for this, so lemme have it.
