Mr. Lucky's Law on All-In

You will go all-in with the worst hand twice and win, only to go all-in later with the best hand and lose.
Avoid going all-in early in the game or tournament unless you have the nuts or you are short stacked and this is the best hand you have seen and the blinds are coming around to you. Tournaments are more than just about survival, but if you want to survive, resist going all in, even at the final table.
Going All-In is not a bluffing option, unless you are the chip leader or head-to-head and have a playable hand.
