C[This is an interesting position in which Leela gives Black A as the best local move, but then Black's winning percentage drops dramatically when White  invades at B. ]

C[ A , B or C were candidates for Black 9, with Leela very much undecided. ]

C[White 10 is a move that can be played against Black's shimari. White is trying to play a kikashi, so Black will counter by playing forcefully with a hane on top or underneath. ]

C[This variation has been seen in many pro games, but is still difficult to judge. White has no ko threat for the ko with White cutting at A. When Black plays first to take at B, Black will need two more moves to capture the entire corner group, making it too slow for Black. Often this corner is left as it is until late in the game, so noone knows if it will live or die. ]

C[With the two moves 122 and 124 my winning percentage dramatically dropped from about 82 to about 60. With either move I should have played at A to capture the three Black stones with less bad aji. ]
