I can relate to what you are getting at, disagree when its said in such a general way.
So many times when calling is the best move, and said like the above will mean lots of people take it literally and will end up being -ve to their game[/quote
obviously i used it in a general manner of course but calling will get you nowhere.if you have outs and you wanna continue its better to raise cause this way you have more ways of winning the pot and also you dont let your opponent know where your at if your on a draw. after you see a flop or after getting raised,you must think about whether you think your hand is better than your opponents or not.if you think it is,then raise but if you think its not then fold.calling is a move that i really try to avoid although i do use it sometimes. depending on what kind of a game im playing.tourney, sit and go, cash, hyper turbo, etc.
