If this happens again, do I bet more on the river?

[Shoe Lace]

I normally don't make plays like this, but I'm trying to open up and play my position more. At the time this felt right.

Also I started to vary my bets a little bit, rather than sticking to an exact "3/4ths of the pot or full pot only".

I decided to show results because hiding them serves no purpose here. Villian's range is basically any 2. I figured I was up against a decent ace (AT, AJ, etc.), and wanted to get payed off on the river, not make him fold.

Btw I was prepared to check/fold to any resistance if I didn't hit the spade.
