Well, those are all huge, so good for you. The system that I lay out works, and is going to put you into the most profitable situations possible. It sounds like you're applying a lot of the concept correctly. Leading, stop and go, tightening up your cold calling, 3-betting in better spots. Just make sure the majority of your 3-betting is coming from position.
I'm glad to hear though, and keep my updated on your progress. I'm about 27 pages+ into the workbook for the first volume, and that should really cement all the concepts in. It's going to have questions like this with explanations:
QUESTION 1 (Effective stacks of 100 BBs)
An average regular open raises to 3 BBs from MP in a 6-max cash game. Based on your HUD stats, it looks like he's opening 17% of hands from that position. The action folds to you on the button. The rest of your opponents are pretty tight in the blinds. Which of the following hands should you most likely fold based on your opponents opening range?
QUESTION 2 (Effective stacks of 40 BBs)
A short stack player that is fairly fishy open raises in a full ring game to 3 BBs from the cut-off. You don't have many hands on him, but so far it seems he's opening at least 25% of hands from that position, and has a total VPIP of 36% and a PFR of 12%. The action folds to you in the big blind. Which of these hands should you fold?
