Good player will check nuts on the river if he thinks player is crazy agroo.
I do it often aginast player like this cose they always bet river.
Most of the time its against 60/25 guys that reraisde your flop c-bet and keep betting. This is a bit different but still can be done if you think this guy is good ... i think i am happy to fold that river |
