Being ‘Pot-Committed’
The beginners at poker games make a very common mistake that cost them money: they make the mistake of betting too much. This is because they do not understand the mechanics of the game just yet, and are only beginning to get a grasp of their game. 
However, there are those hard-headed players who keep on doing the same thing, which can either pay off greatly or be a huge disaster. They call their actions being pot-committed.
Let’s give an example. Say you are playing a game, and you have reached that point where there four of you staying for the river – the other three have folded. Player A goes all in, and so does Player B, and you do as well, and that gives a total of $300 in the pot. Let’s say Player D only has $10. His odds of winning the pot would be 30 to 1, which is not that good because if the other players have gone all-in, chances are they are either very confident with their bluff, or they have really good hands. Still, given the odds, Player D decides to go all-in as well, and gives his final $10. Even if his hand has a good chance of being a winning hand, the chances are still against him because the other players may be able to get higher hands; and while he only has to win 1 in 30 games to make profit, which initially is a good odd, he still has to consider the fact that his opponents were not afraid to go all-in, which means they are very confident with how high their hands are.
Then again, is it a total sin to be “pot-committed”? Well, here is the thing: The only time that it is not a sin is if you know that you have a very strong hand to play by the time the river comes. Otherwise, it is not smart to throw in all your money into the pot without considering whether or not you will win. If you’re a seasoned player who wants to take risks, take twice before going this extreme when it comes to placing bets in the pot.
