COMMON PRE-FLOP MISTAKES
Other than that, it’s pretty simple. You never know what cards are truly going to be a good hand before the flop, and even sometimes after it, but there are a few general guidelines. If you have two low cards that are off-suit (they are of different suits) then you probably shouldn’t play them unless you intend to bluff. A good example of this hand is a 2c and a 7h. In this case you have almost no chance of a flush or a straight. Your best hope would be to catch a pair, and even then it is unlikely that you would have top pair.
If one of your cards is above a 10 or if your cards are suited (from the same suit) you might think of playing, but you want to keep from dumping a lot of money into this pot until you know what the community cards are. This could easily go really well, or really badly for you. Be careful!
If both of your cards are above a 10 then you should probably try to play it. However, when you do, be careful. You cannot imagine how many times you can go in on a hand thinking you have a strong one until you see the flop and realize that you have nothing.
The pros say that they are not playing the cards but their opponents. This is only slightly untrue. Your starting hand is important to winning. The worst hand to start with is the 2 7 of any suit, also known as the split. Your hope here is that you get something on the flop to give you a hand. The best hand is the Pocket Rockets, or the pocket aces. This is a great starting hand; however this hand is just a pair. The highest pair you can have yes, but just a pair. WATCH OUT! Yes, this is a good hand, but many a player has been knocked out of a tournament for going all in on this hand! Try not to bet too big on this hand unless you get another ace in the flop.
