;W[mg]N[Problem position]C[The game is difficult for black and they need to make the most of their thickness on the right side. White's move at 1 is natural and black 2 is a nice response taking aim at an invasion on the lower side. What should black's priority be after white 3?]LB[mg:3][mj:1][mn:2]

;B[kg]C[It is much better for black to immediately jump into the fray and separate white's stones. Ultimately black makes a lot of points while covering some of their weaknesses at the top, and it's unclear what profit white's central ponnuki is generating. This seems like the best way for black to keep in contention.]N[Improvement]
