I folded what would have been a royal flush.

Dealt Kc8d in early position. UTG open raised, and I folded, which is standard for me.

Flop comes TcJcQc. I audibly say to myself "please don't put the ace out there." Of course the turn is Ac, and I would have made my first ever royal flush (also would have been the first I've even seen).

Hard to be mad, because it's a normal fold. Just annoyed a bit.
