Neju (aka Nathan):
I'm an active member of the Boulder Go Club, and I'm somewhere near the 10kyu level (my level in the only rated AGA tournament I've attended).
My favorite topic currently is fuseki. I plays the SanRenSei consistently, in order to learn at least one fuseki moderately. The plan is to switch to a radically different fuseki once I am comfortable with SanRenSei in order to see the contrast, and learn the effects of fuseki in general. I'd like to hear what stronger players consider a good contrasting fuseki.
I tend to be biased against tradition (which may be bad news for go skill!), so I like unusual fuseki. For my level, there are many modern accepted fuseki which my peers aren't familiar with, which interests me.
I feel weak at attack and defense and joseki. I'd like to study attack and defense soon, especially since SanRenSei depends on mid-game fighting to utilize the influence.
I don't play online much, I much prefer the aesthetics of the stones and goban, and the interaction with the other players.
