Apart from bluffing our opponents, of course, we must understand the tricks that are actually used by our opponents first, so that later we can stop the opponent's cards that can harm our bets Sometimes some players like to fold if they get a card with a small number and lure us all in if we get a good card and of course this will make our game position a little vulnerable so sometimes it makes us emotional and even act rashly in the game, patience is something that is quite needed in poker games so that we can play poker with good concentration and a calm attitude so as not to be influenced by the opponent's game tricks.
Not forgetting that we have to learn to deal with our own internal emotions.
That is, I may not pass on revealing information from my easy expression and attitude at the game table. But I have to figure out how not to be emotionally dismayed by a letter, or excited. Because if we don't control this aspect, even if we don't pass anything on to our opponents, we can be so focused on our game that we simply ignore our opponents and this could cause us to lose the game.
