I think I've already explained the reason quite well, and don't feel inclined to explain it again for somebody who has so far failed to give me any constructive advice.
Is there really an ignore function at this forum, or was Vanquish just joking? If there is, how do I use it, please?
2NL is the easiest possible stake to play.
SS are the easiest possible stack sizes to play against.
NITS are the easiest possible player type to play.
So why anyone who is struggling to beat the easiest player type with the easiest stack size at the easiest stakes possible would want to ignore anyone offering advice is beyond me; but this is probably something to do with why you are struggling to beat the easiest player type with the easiest stack size at the easiest stakes possible.
As for not giving you constructive advice. Didn't I advise you to buyin for 100bb and drop stakes until you were both bankrolled and felt comfortable rather than buying in for around 50bb at 5 / 10NL. Not only is that advice both sound and constructive.. but isnt it something you are now doing?
