;W[lm]C[This cut was a mistake in direction of play\: White created a weak group in the middle while his group on the right is not settled yet\; at the same time, the black group running out from the lower-right corner is relatively strong.]

;C[A painful move for White. Black 47 and 49 along with with White 48 and White 20 form a shape called "completely split keima" - one of the worst shapes in the game.

Instead of White 48, it was better to draw back and sacrifice the stones in the middle, for example by playing at 49, but I understand that it's hard to do it once White 46 has been played.]B[jp]
