renton once posted that you always have enough implied odds to call a potsize bet on the flop with a flush draw...
i pretty much agree.

what your missing on raising is that when ever you raise a pot on thr flop or turn you are thretening opponents stack. In essence you are saying that your opponents stack is on the line as we're getting it all in.
Its about pot building. Of course you can raise flop and take a free turn card when you need it or make a trap check with a set to shove it all in on the river etc

by raising you use your positional advantage to force your opponent to play big pots with what are often only tp hands. On sites where players are weak tight raising makes them run so fast they cant fold AA fast enough. On other sites, you get nice odds to call and get called when you hit and shove the river.

Hero needs to know what exactly he is doing versus specific opponents and how he can do it. As a rule of thumb i raise versus good players and call versus bad players as bad players will take hands too far anyway because ZOMG I HAVE TP WITH QUEEN KICKER!!!!!!!!!!!!!!!!!!!!!!!

awwwwwwwwwwwwwww in baby!!!!!!
