River line?

[NigelSmith]

This one's been bothering me for a while and, while it's probably pretty standard, it's a situation that comes up quite often...

Usual Stars Euro-lunchtime crowd, BB is 22/10/1.2 over 175, with a 30% VPIP from the big blind:

And I *swear* I could hear Boz screaming at me not to wuss out coz of the third diamond :-)

So is this a b/c, b/f or, given that I've played a pretty obvious TPTK line, a check behind?

FWIW, if the villain's been collecting stats on *me* he'll have me at around 14/10/3, I've seen him call down with TP-poor kicker and worse and I've never seen him C/R. On the minus side I've had a few people let me bet their hands for them recently, so perhaps I'm coming over as a bit too aggro.
