This is a big part of poker strategy, knowing how to read the table and how others on the table are perceiving your style of play. For example if you are playing too many hands, you might raise on the flop and fold to a counter raise. If you do that several times and all the other players see it, then they might push on you at the next attempt they see. However you might use this sort of strategy to loosen players up or bully tight play, you might lead them along at times by acting weak and calling their re-raises - all the while having the nuts. Being able to mix up your strategy can be a very powerful tool. You should also be able to work out who the weakest player on the table currently is, otherwise it's likely to be you and you'll be leaking chips to stronger players.
If it is a good strategy, but sometimes it does not apply, I have seen how many players just move or make a gesture with their faces and they know what possible game they have, that is; Bad or Good, when you learn to have that perception, what you should do is know how to use that to your advantage, no matter what the player does or says, because it is already known, even if you show that you have a very good game, your arguments will fall. After the 2nd bet, they usually get very excited and that gives them away, in fact there are many players who when they get a good hand, it shows so much that the others end up checking and the player does not win anything.
