riv value overbet shove

[jfish]

villain is somewhat passive havent seen him get out of line too much. i thought his most likely hands were flushes and A5 and did not think he would raise river if i bet normally with either of those and it would be a shame not to stack him. i am repping a very narrow range and usually nobody ever beleives me.
