Through my experience in playing poker for the past 2 years, I see many reasons to call a bluff, or a hand you know you have that is great. Still these are some possibility that it's not the greatest. Do you call or do you not? We all know pocket AA and KK aren't the best. Even though they are, they still get cracked. I had pocket threes once. On the flop hit trips. How would I know that some might already had the straight or higher trips. It's just unbeleivable how things can happen when luck doesn't come your way. Well the question is do you call it all the way down or do you raise it.
