i think a CRAI on the flop is so much better than the donkbet. Hes cbetting this flop a TON and you have good equity vs his cbet range. When he doesn't 85% of the time a non-heart peels off and then leading the turn is a lot safer. If a heart comes its an easy c/f. Checking this flop makes your life sooooo easy.

I really hate the flop bet a lot.
