What I have learned about HU play....

[JuiceyJ]

Im starting to learn that HU play is all about being aggressive. Im slowly starting to find that most people will try to trap you with their monsters. I play aggressive on the button and will always raise 2.5xBB despite what I have. I do this to set up for the kill-shot, they can't put you on a good hand if you play your bad hands the same way you would play your good hands.

I dont know if that makes sense to most. But it makes perfect sense to me. Its hard for me to write what I am trying to say.

I think too many players fold 0% of their hands heads-up. Depending on the opponent, I'll fold 10%-40%, mostly oop ofcourse. If I'm playing the hand on the button (which is very high %) I use a standard raise proabably like 75% of the time. I mix in some odd raises just to mess with their heads.

I fold like 30%, standard raise with average and good hands and just limp in with pocket pairs and 2 high cards. If the game takes too long, obviously, I'll vary it.
On the flop, I like to c-bet when I have some pair or high card (to look like a standard c-bet), check if the flop is not good and also check if I have a monster (slowplay). I've never read many recommendations about HU play, so...its still very intuitive for me.
I like to play OP in HU, its easier to trap.

Have you ever heard about the SAGE system in HU play? When you are shortstack and you play in push/fold mode your opponents tend to make mistakes. I heard its a great strategy against very good players, but I'm not sure if it works properly.

HU is starting with a massive chip advantage, losing 50 flips in a row, then die with JT vs J9. And there is no way around it.
