if a situation comes up such as a 22/19 or whatever reg opens from UTG+1 and we call in the BB with AsJs and the board comes down A37r without a spade, is it ever ok to c/r in an attempt to 'slow him down' and try to get to showdown vs AK or AQ (ie he might check back turn with better and we'll only have to call one bet on river bearing in mind he might fire with no showdown value thinking we took a stab on the flop with a pair and then gave up) as opposed to being faced with 3 barrells when we're not totally sure of his 3 barrelling tendencies.

edit, just realised why this is flawed but i'll leave it here as it loosely relates to the discussion.
