Experienced a couple of things:
One really weird guy told me: "I ALWAYS fold aces preflop. You know what, out of the 50 times i've had aces, i've lost 51 times. Queens and tens are what win me pots."
Later we talked about Gus Hansen and he said "what would you do if you had AK and the flop came KJJ, and your opponent raised TEN TIMES your bet?" I said: "Erh i dno, i would probably fold." He says (while creepingly staring me in the eyes) "GUS WILL CALL THAT. Thats why Gus is a pro. I'm glad we settled that argument".
Weird ****. Later on he told my friend that he was in organized crime, had cooked for 7 royal families/3 american presidents, owned 2 nightclubs, his three favorite things in life were hookers, cocaine and poker, he started crying suddenly because his son was ill etc etc. A very entertaining person
Besides always hearing how online poker is rigged, i've also once spent 10 minutes trying to convince a lady that a flush draw vs. a set all-in on the flop isnt 50/50. 30 minutes later she called my all-in preflop shove with K8 (i had AK).
