Should I cap the River?

[Burnt Toast]

He turns over KJo

Damn it. I guess he wasn't that descent after all.

1st clue - he cold called my raise
2nd clue - he played against my raise with KJo
3rd clue - he didn't put me on a probable full house by the river.

Since the 1st clue was the only clue I had before the hand was over I like to think I would have capped the hand if I thought he wasnt descent.

Anyway, here is what lead me to my weak play. By the time he caps the turn and I bet the river a descent player would put me on a full house. A descent player would have reraised with preflop with QQ and TT (if he were to play them). AsQs is the best cold calling hand that would give him a full house.

Is it ludicris to put someone on this hand and not re-raise without knowing them for years?
