Hold’em is known to be a high card game. The players that are holding two good high cards have the best advantage at getting the best hand or a normal draw to the best hand after a flop.
You should only play strong hands that will withstand a raise or even multiple raises, from early betting positions. Play medium strength hands from the later positions only if you have a good chance of seeing a flop at a reasonable cost. Play all strong high hands most of the time, and I suggest you play them very aggressively.
Try to take all the raises you can get. If you don’t thin out the competition, you reduce your chances of winning. Plus when you play aggressive before the flop you add credibility to any strong play you might want to use in the next round, if a not good flop falls and you want to try a steal. You have to be ready to fold your high pair hand if you get a lot of action with a threatening flop.
