re: Poker & Understanding EV
Red line vs blue like doesn't really matter if your winning. My red/blue lines diverge in the opposite direction because I'm an crazy agro dbag. Betting more and more often makes people fold so your nonshowdown winnings will improve. Tighter starting ranges are one thing that will improve the blue line but you seem to have that pretty well in hand.
There are a lot of ways to transfer showdown winnings to nonshowdown winnings and vice versa.
