The reason I wanted to know the EV was actually to know if surrenderEV (-50%) was better than the best EV decision (could still be negative EV therefore) from the chart. So you were ahead of me there.
TBH my neural blood flow is not existent, because I cant make sense of your chart. The only thing I can think of is that you mean pulling out totally is that you receive your complete bet (and these are the positive EV situations)? Is this even a rule somewhere?
