Gu Li's Brilliant Moves
This is the time for Gu Li's tesuji.
Ed? Black 'a' looks like a good move to me. If white 'b' black pushes through at 'c' and captures 2 stones instead of the 1 captured by pushing immediately. If white 'd' black plays 'b' and has made it up to the 4th line. If white 'e' black 'd' appears to catch the cutting stones.
Dieter: Brilliant indeed!
Jasonred : Hold on... so, the extra stone at 7 and extra stone captured IS worth the weakening of the main group? I assumed the 8,9 sequence, is that correct?
crux: It appears that professionals think that way. There's a similar observation somewhere in Invincible, where a move that causes Shusaku to capture three stones instead of two is called the losing move.
Bill: I think it makes a difference of more than 4 points.
