NL$1000| Is this a terrible or sound play from me?

[Acevader]

I understand the merits of just folding PF here but I'm generally very tight in SB and like to let the BB know that I'm not going to just auto-fold any non-premuim hand to him all of the time.

Villain is 19/10/1.5 (290) and whilst I've not shown a hand down at this table I've not been very active so he should have no reason to suspect I'll get out of line.

I fear there will be screams of 'fold' preflop so lets not debate that one in and out. Flop, turn, river? Spew, spew, spew or good poker. By the river I was fairly certain of villain's hand.
