check call against unknown, i guess.

I tend to c/c vs an unknown, youve got the equity to and we dont want villain to shove as we have to call but we'd be way behind. I also think fold equity is minimal with such a safe turn card falling, id rather see him float a couple of flops before i double barelled.

Thats a good point about the turn card. If that was an A I guess I should be more willing to fire it again then a 3.
