You should almost always raise this bet if you have a weak hand because by making this bet, your opponent is saying, “I have a hand I don’t want to call a bet with but it also might be good. ” Usually your opponent will have something like J-8, 10-9, or A-4 and is trying to “find out where he’s at” by leading into you. When this happens, you should almost always give him bad news by raising, regardless of your cards. If he does call, be prepared to fire every street, unless you know he is the type that will lead with strong hands to try to induce a bluff.
While it is important that you can determine your pot odds, it will become simple with experience. You don’t have to be 100-percent exact with your pot-odds calculations. If you can estimate decently well, you will have no problems. Say you have A-4 on a 9-6-2 board. Your opponent goes all-in. Should you call? The answer depends entirely on your pot odds. If you assume your opponent has a hand that is 9-8 or better, meaning he will always have at least top pair, and he never has a flush draw, which may or may not be true, you will win around 42 percent of the time.
I don’t play these games to make money, even though that is a nice side benefit. If you aren’t focusing on the game, you are basically playing to pass the time. If you want to improve your game, play few enough tables that you can still concentrate on what is going on. You must be able to follow every hand and actively put each player on a range. You need to pay attention to every detail about the table while you are playing, such as your opponent’s statistics, everyone’s stack size and the payout structure if you’re playing a tournament.
