You can't know your exact equity, maybe he has Axs and doesn't want to fold to a single bet on such a dry board and tries to get to a showdown if you give up on the turn.
It's not about only pure equity that we have IMO. On the flop he probably won't fold much but on the turn he folds a lot if he doesn't have a K in his hand. Even if he calls we still do have outs and there's still river to play. Though all this of course depends on the opponent.
But if we're cbetting the flop and giving up on the turn on that exact card I'm not sure if we should even bet the flop then. Think about if you were the SB in this spot and you had a middle pocket pair, like 66-TT - would you instafold the flop to one cbet? Probably sometimes, but sometimes not - but you would for sure fold those hands on the turn. 66-TT are in total 30 hand combinations in total that most likely will fold the turn. Sure, if he has KQ, KJ he probably won't fold on the turn. Those are 24 hand combinations in total. KT might or might not fold to a reasonable sized cbet on the turn depending on the villain.
If you bet the flop and check back turn, you have no idea what to do on the river - he might rep the king and bluff us off the hand on the river.
Maybe it's not necessary at the micros to do this, but if you bet AK/KQ etc twice here it's probably good to bet this hand too vs the regulars. Vs fish I could just check back for a free card and stack off their top pair or lower flush if we hit.
