Making the 5-point and the barpoint is a pretty strong move which usually has the disadvantage of Red losing a lot of gammons if White hits one of the many indirect shots. Since White needs only one more point, these gammons don’t count anymore, and Red should risk the shots. In any other situation, Red should move 11/9 6/5(2).
