Poker is a game of skill and luck. You can't be lucky using SSS PreFlop as you nearly always have the best of it and when you get your chips in.
Villan will either fold worse hand, call with slightly worse or much worse hand like low pair or sc's. You should win and will most of the time or he might get lucky which will also happen regularly.
The only players who can get lucky, varience I think you call it for some reason, are people not playing SSS. If the only luck you can expect in a poker game is even or bad luck you have a losing stragrgy.
