Coming out of hiding for 1 post....
I don't recommend this play at all in online play. You will not have the information needed to play correctly after the flop.
Since you may do it anyway...I will mention some times when it will be most useful.
(1) When the table is very tight. This is quite uncommon online. To decide if the table is good for this type of play, keep track of how many players see the flop on raised pots. If players are raising around 3x or 4x the BB, most flops should be taken by 2 players, sometimes 3 players. If 4 or 5 players are typically calling these raises before the flop, your play will be a disaster.
(2) When your opponents are capable of playing good poker. For your play to work, your opponents must respect the hands you are representing. If they cannot fold when u have them beat, they cannot fold when you act like you do. If they cannot fold when someone outflops them, they cannot fold when you outplay them.
(3) When you are running cold. As mentioned, this play requires respect and solid play from your opponents. You don't want opponents trying to keep you honest with marginal hands. If you havent played much lately, your aggression will be repected.
(4) When you know your opponents. This is the most important thing! If you don't know when your hand is the best hand (nearly all the time), you are not good enough to use this play. If you can read online players this well, you are a much better player than I am.
(5) In cash games. Everyone will be playing weaker hands in tourney play and this is not the situation you want for this type of play. You will find this play works better at higher stakes, where the players are better and everyone cares about the money in front of them.
(6) When you are the only player doing it. If other players are playing like this and you know it, you should play straightforward and break these players by getting in with the best of it.
Sammy was playing with the best TAG players in the world in that game. He also caught his share of starting hands and good flops. Also, (very important) he was playing with his opponents money. He would have mixed up his play more if he lost a couple big pots and was risking his own cash every hand.
I would just not do this if you play online. Save this play for when you get on HSP.
