all that matters is the green line, try to pay attention to the red line, but it's always about the green..........
what it usually means is that you're folding to much or bluffing to little, but as long as you get a decent BB/100 is all that matters........... obviouly depends on what your playing though...............
what some people do to get the red line up is bluff a lot, so their graph look just the opposite from yours, the blue line(showdown winnings) is losing money while the red is sky high.......
What i suggest is dont put any money in the pot if your behind, and mix some bluffs against the right people, dont do it against bad players, cause they're usually stations(dont, cant or wont fold) do it against people that you know that can fold a decent hand........
