Learning how to win at online poker requires as much effort as winning in real time at a poker table but the strategies are slightly different.
Understand the odds - There is no point in playing poker if you do not study odds about your hand being a potential winner or not. Even if you intend to bluff, understanding the odds will make you bluff better. For example, let's say you have a pair of sevens and the board shows AK-9-2. Your opponent is all pumped up for action and you feel your only chance of winning would be a third seven down the river. Your odds of getting that third seven are almost 42: 1. Fold up.
Spot that bot - A poker bot is a small program being used online players these days. They have spoiled the fun of fair play but there is no way to stop them. Best is to learn to spot a bot. A player has about a minute to make a decision when it is his turn and you would, as a human, take almost all your time. Start noticing how fast the others are playing. A bot is way faster. Also, Take note of players who are 'always there' and never seem to make a wrong call. With practice you will be able to note a bot easily.
Fish for the 'fish' - Ninety per cent of poker players are 'fish'. These are the ones who play as an addiction and bet on virtually every hand. The more they lose, the more they play running their accounts bone dry. Some of them are involved in several hands at a time. Do not be a 'fish' yourself but keep track of other 'fish'. Once you have a fair idea of the table position, have spotted the bots and the fish, wait for your strong hands and go all out. Do not play on loose hands against the 'fish'.
Speed up - The thrill of online poker is in the pace of the game. Get into the habit of reading the flop fast and accurately. It is always good to sit out for a few rounds the first time you start a new table session till you get the feel of who's doing what.
Scribble clues - The advantage of online poker over table poker is you can write down patterns of play as you notice them. Whether you write down 'clues' on a notepad next to your laptop or in the 'notes' tab on poker sites, you can raise your wins by taking notes. If a player spent a lot of time before raising and you keep track of that hand till showdown, it's a huge clue to how they are thinking.
Begin small - Winning more is often based on losing less. Do not put more money into your account than what you would not mind throwing down the drain. Also, begin at small tournaments till you are confident about playing with the big cats.
Budget your time - Try and play an entire tournament. Often, staying long enough to complete a tournament puts the odds in your favor for coming away with an overall chip win. It gives you an edge in understanding that particular group and line of play.
