Cut Off Or Defend
Conceived by HolIgor
This is to explain the dilemma.
This is from one of my recent games. Answering Black's attack with the marked stone, White played the marked stone.
Obviously White wants to settle his group. Playing a Black gets quite a large corner and still can attack White.
But answering b cuts White into pieces. What kind of approach would you choose?
Black 3 was wrong. It was not urgent. If White 3 then Black a. Thus there was a possibility to get an large move elsewhere.
