On Flop, i usually c/f that with an occasional c/r. After my bet on turn, a check on river might indicate i just used the King as a scarecard. I want him to bet weaker hands like PPs or bluff, rather than making these hands fold or getting raised. Is check/call a good line here on river, or do you think unknown might call more often than he would bet himself?
