Vulgar.
Black 1 wastes aji.
The automatic moves from 2 though 7 end in gote
for Black and for just a few endgame points.
Black can do much better.
Good style!
Black 1 fully takes advantage of the aji.
White has to fall back with 2.
Black 3 reduces White in sente. Up to White 4
is optimal play for both sides.
White variation.
White cannot cut after Black 1, but blocking at 2
doesn't work either. Black can turn at 3 to
significantly reduce White's upper territory in sente.
