This has been the kind of crap I've been dealing with and managing to lose 3 BI's since coming back....I don't know, seems if I play tight I get no action though looking over my FT stats since coming back to playing I'm running 17.73/6 with a total AF of 0.87 so I'm not playing tight but I'm running way too high in the SB at 33% and my W$SF is only 36%.

I do need to tighten up more at FR so will see how that goes tomorrow......game over for me tonight I think.
