My big leak

[MixedNuts]

I think that this is one of my biggest leaks, going for draws and missing. It seems that I do this all the time and slowly lose money. I never seem to make it up when I do hit my draws. The Joker is a maniac and has to put in the last bet. The Penguin is pretty ABC. Any thoughts?
