Vs A Loose-Passive (Calling Station) Player
You should start limping most of your hands and trying to get value when you flop a hand postflop. If you do elect to raise, try to raise 2.5x the BB. You should raise about 50% of your hands against this opponent.
Vs A Tight (Nit) Player
You should start raising most of your hands and trying to get value when they fold pre-flop or to your cbet on the flop. When you raise, raise 3x the BB, and cbet around 3/4ths of the pot every time. You should raise about 90% of your hands against this opponent.
Vs A Loose-Aggressive (Maniac) Player
You should raise strong hands and suited connectors on the button. You make your money against a maniac by flopping a strong hand like a straight or top pair top kicker and letting them bluff into you. Do not play trappy before the flop. Just raise and hope that they 3-bet you when you have aces. You should raise about 66% of your hands against this opponent.
