I played alot at these table stakes and had to adjust my play for these stations. I think you really need a good read on the villain to make any bluff. Most of these guys never fold 2nd pair, ever. At least in my experience.

1. Call. I laugh when people bet 1/20th of the pot. Are you going to fold? No way.

2. With the kind of stats you posted this guy can be on any 2 spades, a 10 or maybe even 89o. This guys range is to open for me on the flop and when I am in doubt I fold.
However, if you think you can stack him if you make the full house, i think you can call profitably here. Your getting 3.75 to 1 on the turn (pot odds) and he has like 9 dollars left (implied odds) and your 4 outs gives you 10.5 to 1. To me this looks profitable, correct me if I am wrong.
