I learned from an early stage that since most tables are paying out 36 to one if you hit a number dead on, you should probably bet at least more than 20 chips at a time. Even if you bet 30 and you hit a number, you still profit 6. But on the flip side, if you lose, you lose 30.
Also, if you are going to bet on a 50/50 bet where the minimum is usually 5 instead of 1 on the inside numbers, you should bet bigger than you would on the inside of the table. The chances of you winning are greater but they only pay 2 to 1 odds.
Also, I think betting on the 0 or 00 is a suckers bet and should be avoided by smart players.
