If you want to earn profit with poker games in the shortest amount of time possible, your best bet would be to play at Sit and Go games, which are more easily managed because they have a distinct beginning, middle, and end. The fact that Sit and Go games are softer or require less depth in playing styles means it is possible for you to see a reasonable profit if you can play appropriately, and can multi-table as well as able to resist being too emotional in playing. Additionally, you need to employ some basic Poker Sit and Go Strategy, such as the following:
A good Poker Sit and Go Strategy starts early on, before even joining a table. You need to first consider whether the risk versus reward ratio of the game needs you to play aggressively or conservatively. For example, if the blinds were pretty low during the start, you would be wasting your "secret weapon" by bluffing early. During early stages, majority of your opponents are more aggressive and tend to gamble a lot, particularly because they don't feel comfortable until they add a notch to their list of double-ups. With low starting blinds, it would be a good poker sit and go strategy to play a little further back and let them unleash all of their best hands. You will get rewarded just for surviving, anyway. If you wait until your opponents are fewer and the blinds are higher, your strong hand and aggressiveness will be more effective and will have more rewarding effects.
When the sites have become tighter, another good poker sit and go strategy you can use is called the Continuation Bet, which is when you immediately make a bet after the flop that gets dealt after you've raised the hand pre-flop. This puts you in control of the hand, and by raising the flop, your opponents tend to check to you. Betting at this point, usually between half or the full size of the pot will make your opponents put you on a bigger hand or a bigger pocket pair. When the board finally comes out with 3 rags, or if your opponents only got a fraction of the flop, and are immediately faced with another bet from one of the preflop raisers that followed suit, they tend to be scared and just throw their hand away.
The good thing about Sit and Go poker games is that they don't require a large amount of time investment, which means you can earn a good amount of profit merely by playing a game here and there and quitting once you've gone past break even. More importantly, don't forget to have fun while you are at it. The fast pace of Sit and Go poker makes it appealing even without money involved, which means the addition of profit allows you the luxury of earning money while playing and having fun. Using poker sit and go strategy is not that time consuming and will only require minimal effort in exchange for consistent profits.
