He is 21/20 after 278 hands with steal on button of 50%

Comments on all streets appreciated.

OTR he checks back all his show down value hands, but he has also a bunch of K, Q, J high hands do you think he is bluffing those and I can profitably call this river?

My perceived range should be something like low PPs (33, 55, 66, 77), perhaps some 8 like 89, 87 and missed straight draws (56, 67).

From his perspective it doesn't look like a good spot to bluff. Is this an easy x/f than?
