When I say situations where c/calling is close to optimal play, I mean where you catch a minor piece of the flop against a maniac and call it to the river. For instance, you have 67o in BB, call a SB raise and call down on a board of J72 three suited.

Edit: I am in NO WAY suggesting that check calling is an optimal play in all situations, even against maniacs. Of course you need to bet strong hands for value.
