For example, the flop comes with two players after a raise. The flop and turn are passed. A player bets on the river and the other a bad LAG, rises. Depending on the cards of the board, this raise is almost always a bluff. LAG evil will never check a good hand behind twice and the river card is not one that probably has helped you to have it. So either the bad LAG has a very strong hand but is unlikely or has decided, once again, try a bluff. In general, the range of LAG hands after this action is significantly unbalanced to the weak hands. If you would like to know more then you should visit Jill Schlesinger.
The best way add deception to your game is to constantly read your hand as you play. After each decision ask yourself: "What kind of hands would have played this way?" Think of each hand you might have in the same way you try to read the opponent's hand. Do not worry for now about what hands your opponent may think you have. Just think you could have your hands after playing well. Simple hand, it is normal that your ranges are quite broad and balanced. If you play a solid TAG game, increase your range of pre-flop is probably misleading. You could have great partners, premium hands, small pocket pairs, connectors could also have suites and trash. Similarly, the range of your continuation bet is also quite misleading. The fact that your opponent see you bet the flop will not give too much information about your hand.
