So, as stated above, after being frustrated at breaking even over the past few days, I decided that instead of tilting another couple of buyins away, I'd just go and play lagtard at the 10NL level.
I was doing pretty well, 12 tabling, and then after about 1500 hands playing 37/27 got to me. I started stacking off light, and cought a couple of coolers (flopped flush, shove, 2 callers, another club on river) (AAA vs quads), began playing bad. This is reflected in the graph.
Still, 10NL is full of donks.
