I felt guilty not being able to post in this thread so I got my lazy arse in gear:
1.Watched 2 bottomset videos and a GoldSeraph video in the DC Ringsside series.
2. Went through my HEM DB looking at how I play in 3bet pots, and how I isolate IP and OOP.
3. Went through some poker maths re. 3betting and "risking A to win B" with Muzz.
