[gmandan]

How badly do the beats affect your bottom line? I've just been finding myself doing great during the beginning of a long session and always ending down 30BB each day for this past week. The sets are really pounding me on the head and just catching myself in bad situations (my AQ vs. villian's AK) multiple times. Does even a little chip spewing make a positive winrate into negative and is impeccable poker play necessary to even come out ahead at least 1 BB/100? It's just been tough trying to make it through 1/2. I'm definitely over-bankrolled. I've just been frustrated trying to improve and not be so result orientated but with such a small sample size of hands I just feel lost even after reading/studying through SSH and posting/reading hand examples. Any other help?
