the original content of this page has been moved to BQM563. This page is being reused to discuss the sixth move in the low chinese opening. There is already the low chinese files but its organization is author specific and its content is out of date
This is the position in the low chinese opening, before . We're assuming a ni ren sei formation for White on the left, as is very common. According to An Younggil of gogameguru, a-j are common options for . We'll highlight a few of them.
White's high extension of and keeps the central influence of the chinese formation in check. Next, Black will use his sente to dismantle White's left side with a or c, or build the upper side with b. If is played at immediately, the follow-up remains largely the same.
Nowadays (2012), a steady move like is popular with the professionals, which avoids direct contact with the stones of the low chinese, while keeping its influence in check on a larger scale. Next, Black who is locally unaffected by , turns his attention to the upper side. is commonly seen, but local continuations like a and b are also common.
Another idea is to play at the top immediately, allowing Black to form an ideal territorial framework at the upper right. Next, Black will naturally shift his attention to the lower left, using the influence of the low chinese opening to build.

Elom: I once heard that this formation is bad for black. Why?
