So this is probably one of the worst played hands I've seen in a while. Did you think you had the nuts with 3 diamonds and both of you checking down? It's okay to fire out your $1 feeler bet on river but when you get checkraised twice, the second one being all in, WTF were you thinking?
Seems Villain knew quite well what he had, considering he stacked you after you somehow called a 4-bet all in on the river with the eight-millionth nuts
