Poker is all about what kind of a player people perceive you to be. If you open the game with a raise (regardless of whether your cards are good or not), while your opponents sit out, they will think you a risky player. Your game strategy will affect your opponents game strategy, and if you raise a good hand and then show or even a bad hand, it will decide game-play. Your strategy can backfire if your opponents play inconsistently and their decisions become easier to decipher.
When your opponents fold and you proceed by showing your big-blind may be thought of as an innocent decision. What happened was that on the basis of your decision, people folded their cards, although they didn’t know what cards you had no could they gather any insight to your strategy. They may hold true till some player catches on to you and begins to read your weaker hands and tries grabbing your blinds, which may also prove to be very effective. This way, next time you have bad cards, he’ll win. Likewise, if you continue to play with a high pair of cards (A A) and your opponents are forced to fold, that will make people vary of playing with their average hands later on in the game, which may be either a good thing or a bad one for you. There is no need to take the chance.
Another strategy employed by players is table talk. That plus showing your cards can make your game very manipulative and deceptive. You can inform your opponent that you’re holding on to good cards while they are thinking of their move, and later in the game you make a high bet which will cause them to sit out. That way, your high hand can inform others that you were not lying in which case, you can use that to bet on bad cards and people will fold, because you’ve established your reputation as truthful. Most experienced poker players will see through your table talk and won’t so easily be trapped into folding. So watch out for them since they’ll know you’re bluffing when you bet high and could lose potentially. Your strategy could be made evident to everyone and although, it could work positively, it could also backfire. But it is useful since they won’t really know what you’re up to.
Make sure you’re aware of the rules, wherever it is you’re playing. Many rooms have a “show one show all” policy, that doesn’t allow a player to show cards to only one opponent. Likewise, you may not be allowed to show only one card, which may be used by your opponents to study your other card.
