So I'm going to start an operation solely on heads up play. The majority of the play will be cash game heads up but I do play some SNG HU as well.

I have 40 buyins for 50nl and will roughly operate on a 30-50 buyin scheme for BR management. My goal for this operation is to learn how to be a better heads up player and obviously make some money in the process.

I've been playing heads up for about a week and so far have been rather successful. So far what I've learned is:

a) Tight is very hard to play against
b) You don't call allins with top pair unless you have a great read
c) Player selection
d) Player selection +1
e)Dogisheadsup is a great source of information
f) Patience. Yeah you want to get in a 3bet/4bet donk war with that maniac but you'll make a lot more if you wait and trap him.
g) If you're not making money (even if the guy is awful) find someone else to play

I have a few weaknesses:

a) 3bet donks, 3bet > 30%. I don't know how to counter it besides waiting for a good hand and I usually get frustrated and tilt far before that. Good 3bettors can avoid my monster hands too. Dogisheads suggested either minraise/limping more or calculating a +EV 4betting range.
b) Minraisers. I can't make money off them. I can't build pots up to pay off my good hands.
c) Postflop play. I'm far too passive postflop. My continuation bet is way too low, I need to checkraise more for balance, and I need to two barrel more. I just don't know when to do so.

So yeah, any and all advice is appreciated. I'm going to load up some tables; I'm looking forward to seeing where this operation leads.
