[Dulce Liquido]

I don't really like preflop, but that's just a matter of taste I guess.

I'd fold flop.

I'd make my turn bet a little larger, although I guess 20 is fine. Are you betting 20 to fold to a shove if he CR's?

I think on the river there are a few 2pr hands he might have (7,6 5,6 4,6 all these depend on his preflop play though) and it's unlikey he's checking the river with a str8. I probably shove (for value), but I don't mind checking.
