After checkraising flop and getting called, best move is put villain on a range and evaluate his tendencies. Therefore, you may assume how often will your bluff be successful. For example, if you checkraise + bet turn vs villain who is known to call multiple streets with middle/bottom pair, gutshots and overcards you will have no success in making him fold anything except hands with absolutely no potential to improve.So, generally, you shouldn't be bluffing any boards unless you have a good reason to.And why would you try to bluff pot commited villains, since pot committed obviously means that he won't fold ever?

First of all we should know what you are playing. Bluffing in hypers is different from bluffing in turbos.Then there are differnt ways of bluffing. One is the C-Bet if you do not hit the board. This is pretty much default. Than there is abuseing regulars weekness (being a regular yourself you should be pretty familiar with what boards the regular will make a cbet or not). On a flop like A72 rainbow I have no problem check/raiseing my regular opponent because I know that it is a perfect board for him to represente the Ace. If he calls me, I give him lots of credits and wont bet unimproved again - unless I have some pretty good reads ofc. If your opponent is not a total morron he will give your check/raise lots of credit and would very rarely bluff into you on the turn once you checked unless he got a very strong hand also.
