Choose the best table. This is probably the tip that will increase your profits the most. If you are capping yourself at a certain blind level (you normally want 200x big blinds at the table), then use the search function, which almost all poker rooms have, and find the largest ‘average pot’. Tables with large average pots mean players are betting their money wildly, and it becomes an ideal place to make a profit.
Bet before you call. The general rule of thumb is: you need to have a better hand to call than you do to raise. If you call a bet, you learn nothing about their hand, you don’t increase the pot (by as much as a raise would do) and you don’t give yourself the chance to win the pot there and then. If you don’t have a made hand (e.g. flush or straight draw), make the bet anyway! You could win the pot, you could hit the flush or straight on the next card or you could get re-raised. Even if you do get re-raised, you have learnt a lot about your opponent’s hand, and you can re-evaluate your next decision.
Take your time. If you have your hard earned cash on the table, you should take the time to think through every decision with detail. Think through how your opponent has acted in previous hands, what he could have that beats you, what he could have that you beat and whether you have the Expected Value to call.
Bully the weak players. No, I don’t mean call them names – bully them at poker. If a player is playing timidly, and is folding anything but aces, you must be a predator and extract as much money out of him as possible. If he re-raises you, you know he has the nuts, which makes your decision easy!
