Never keep a 'Kicker' - a high card with a pair.

Only after one player places a bet the real betting starts. Each player in turn can either 'Call', 'Raise' or 'Fold'. To fold is to pass or drop out of the round and not play. To call means willing to match the bet, and the same amount must be placed on the pot. To raise means to match the bet and add an extra bet.

"You know what luck is? Luck is believing you're lucky...to hold front position in this rat-race you've got to believe you're lucky." - Stanley Kowalski, A Streetcar Named Desire
