5/10: River Decision in a Blind Battle

[Mathieu]

The only way that you can be good is if SB also had a 3 and is now bet/folding the river. If he had 2 I'm thinking he would have folded, and a 6 or A just made it.

How many 3x does he complete in the SB compared to amount of 6x or Ax? Is the ratio better than 1-6.5? If yes this is a call.

If the structure is 2/5 I really don't think villain will play enough 3x to warrant a call.
