I'm sure you mean well, but advocating a check/call in this situation against this type of opponent is just not very good advice.

If you were against an opponent whose PF range is much wider, and who would be more likely to bet part of this range that we beat, and who would be more likely to bluff raise with hands in that range that have zero showdown value, I could see the value in a check/call line.

Here, however, the villian has a narrow preflop range, and very limited post flop aggression. He is virtually never betting any hand on the river that hero is in front of, certainly not often enough to justify a call. This villian also is never bluff-raising this river. He will, however, call with many of his non-pair but showdownable hands.

The only reasonable choices for hero on this river is to bet/fold to collect from A-high hands and/or fold 88 or 99 and/or avoid showing his hand. Check/fold is also viable, but not optimal as this villian is likely to call with A-high.

The numbers your throwing out mean very little because you're not taking into account the cominations the villian is more likely to have played that way, and what he's likely to do with them.
