[goban move=150 diagram=true coord=true float=right width=50%][/goban] Hi Guo Juan !

During a game review with Justin Teng, a yose question appear and it was hard to find the answer.

It's black turn and we were considering moves A, B, C, D.

Personaly, I would be tempted to play A in sente and then go to C.

In the game, black plays E and we say it was not the best.
