protect your equity, you have no idea of his bluffing frequencies.

i agree to some extent. its something ive been thinking about lately. i think part of the reason you check is to induce bluffs from hands you beat. supposing you are up against your standard tagfish who will call u'r 3bet with 22 "for set value" and
i) never gives you action with his hand he is playing fit/fold with even if you underrep your hand by checking the flop
ii) never bluffing when you check to him

yes he only has 2 outs, but you havent gained anything from inducing bluffs...coz he doesn't bluff. so you are better off protecting your hand instead of putting yourself in a sort of negative freeroll where he only gives you action with his hand if he improves, and you dont gain anything by giving him this chance from bluffs.

pretty sure that didn't make much sense.

i do sometimes check because i "dont want to turn my hand into a bluff". its really annoying..ever since i learned that concept ive been ending up in really tricky situations where i have to call off my stack with KK on A high boards just because ive underrepped my hand.

i think most people do bluff enough to make giving a free card a decent option, but if you know somebody doesn't, then you might aswell protect your hand i think.
