I have had several straight flushes and I'll tell you dumbest I ever played one.
Dealt:
My thoughts -
Check my BB
Flop:
Great. Open ended draw.
Turn:
Nice. The straight is made, but I've got the donkey end.
River
Rats. Board is paired. Now I got to worry about flushes, full houses, and quads.
I had completely forgotten I had 4 spades before the River. Didn't notice the the 8S made a straight flush.
I was bummed out because the damned card was flashing danger.
I called the bet on the river and one of the players showed a hand of 88877. I turned my hand up and said, "Damn, I made a straight on the turn," and gave up.
Another guy says, "Actually you have a flush." And I said. "That still doesn't beat his Boat."
Then somebody pointed out I had the Nuts.
Then I was really bummed out because I thought I had mucked my hand.
But the dealer pointed out that my cards hadn't been fouled and I was awarded the pot.
It must have been about 10 hands before I got my head back in the game because I couldn't believe what an idiot I was.
I think that must be some kind of record for Poker stupidity.
