Go with the streak - Bet more when you're hot, less when you're not.

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.

"The subject of gambling is all encompassing. It combines man's natural play instinct with his desire to know about his fate and his future." - Franz Rosenthal, Gambling in Islam (1975)
