There are plenty of players who are probably winning/break even players who do the standard "pro" moves they see on TV. Such as getting into a 3 or 4 bet war with Ax in a blinds war, or raising or re popping a pot on the button with a marginal hand. Or making the squeeze play when they get a raise and a call or two and the action is on you. These plays are considered standard on every level. But in live poker playing with a a knowledgeable player can you guys really say these moves are more +EV then -EV on a graph?
I mean sometimes you hit flops with these hands and it makes it easier, but what im saying is because these moves are so widely known as standard play, people know you know why you are making these plays and therefore make moves you on.
Lets face it poker is getting tougher and tougher and you will probably have 2 or more thinking players at your table on any given day. Do these standard plays but you in tougher decisions usually because they are so standard?
Like everything in poker, you just pick up villain's tendencies and adjust. If you've seen villain fold to 3bets/squeeze then you can go ahead and make a move. On the other hand, if you think villain is suspicious of your actions, then you should exploit that by opening up your range and squeezing for value.
I think a lot of people make the mistake of not considering why they are making certain plays.
They're standard because the math supports it. I'll just use your first example of a light 4-bet. If it's not profitable it's because they 3-bet too tight or call 4-bets too loose. Either way if they make the standard play unprofitable they're giving you money somewhere else. You just have to know the game well enough to figure it out.
