>_>

The kind of problem in go im never 100% sure of the solution... d18?


Thibault de Vassal    (2007-02-16 22:58:40)
Do it simple

Hi Sebastian... No, easier :)

Sebastian Ruiz

easier? O_O..... >_>.... <_<.... >_<.... <_> how? xD e17?

:-)

I couldn't justify, but the 'natural' and good move seems to be d17

Well

Normally in this position of the opening, it would go E17 F16 E18.

C17

Bc17 is the only move to protect the corner: if black play the very weak moves: D18 or E18, white can invade in c17 and live easyly. if black play f16 it lead to a known variation where white is unconditionaly alive in the corner [[Bf16 ; Wc17]] 1) Bd17 ; Wd18 ; Be18 ; Wc18 ; Black must play E17 (or sacrifice E18) ; Wb15 2) Bc16 ; Wd17
