I saw a royal flush online once at a $5 buy in tournament.
The player had AK both clubs suited and hit a dreamflop of QJT all clubs, he checked the flop and weakly slowplayed it till the river, as a royal can't make you a lot of money.
i have only gotten 1 royal in my life but it was in a 7 stud h/l game. about 2 or 3 times i have folded a hand that would have made a royal but i'm sure that has happened to all of us that play online regularly.
I`ve had 6 royals in 4 years,and one that was rabbited after I folded q 10 of clubs,culd call it 7 all together,but I don`t thibk rabbiting is accurate as the cards are constantly shuffled and if the hand was played it may have been different.
