Well in hindsight I guess I would...

Make a pot sized bet (about $5)
Dealer would have probably called
Turn comes club
I'd have been worried about 2 clubs and two spades and bet 3/4's of the pot, so about 15$
Dealer would have called
River comes 3rd spade
I don't know what to do check? This is where position kills me
At this point he'd know doubt move all-in.
I'd like to think that at that point I'd see my 3 of a kind had shriveled up and save my remaining chips. In reality I still might have put him on a bluff, as I had many times that day where i wanted to call but had nothing, so this time i still might have called.

The other way I looked at it was this: This guy was going to call any bet I made, so the best thing for me to do was make him pay the maximum price to try and make his draw. If we did it 10 times I'd win 7 of them, so I made him pay way over the odds really.

With my lack of experience I'm really not sure.
