I was pretty certain I was beat here. But I figured the easiest way to lose the least money is to raise the flop. I figured the guy with KK would reraise not to let the AKs or AK with A hearts get a free card (me if I was the one). Or AA would reraise here. Instead they all just called, creepy.

So on the river would you bet considering no one should strength on the flop or turn? My instincts said check but logic said bet because a better hand would have reraised at some point.
