Don’t show your hands
Many people who fold out on their hands have the habit of letting others know what cards they held. This habit is very bad as it gives information about what cards you will attempt to play.
Based on this information the other players will be benefited to play a better game against you.
So, if you have taken the option of folding, do it without letting the whole world know what you had been dealt with.
Instead of giving out information, you should be the one who is an information seeker. Ask questions and wait for answers and listen to them carefully.
Use the information that comes in your direction to your advantage. Ask out for opinions. When people are asked for their opinions, they think highly of you and give out information easily.
