[Lawman]

What's the purpose of the river bet?

[monkover]

i´d bet a little more on the river but i´m sa well folding to the shove.

[sightless]

vs such villain fold

dont bet so little in such spots, if you get raised u would be very lost

[yntm3]

Board has filled in every way possible so I just fold since I haven't invested a lot.

So should I c/c the river or bet like 5 and fold to a raise?

Fold as played. Ugliest river ever.
