Opening the game up.....

I think the main reason you're getting spanked is because you don't play well postflop. Playing tight makes for easier postflop decisions. You generally don't have to deal with middle pairs, gutshots w/ overcard, and TPGK decisions that often.

I'd start with opening up my starting hands more in LP. Playing OOP would be next.

Someone said don't multitable while you're adapting, I agree with that.
