I am trying to improve on this aspect of my game. Poker is a very emotional game and players can be manipulated by table talk of the lack there of. I am wondering if anyone has written material on this subject. I know questions like,"Will you show if I fold?" can help you gain information. Being friendly to some players may help you win their money by either preventing them from betting or putting them on tilt when you bet against them heads-up. Other players can play worse against you if you are gruff towards them since they might lower their hand standards to try and get you. Does anyone have an opinion on this subject. Is it worth trying to get better at or no?
