10.37-32
[ 10.37-31












Computer says 37-31 is better than 37-32. I can't get the reason. Maybe black can't keep a piece on 23. Black 24/19 without 23 is not so good. (?) 18-23 11.42-37 23x32 12.37x28 ]

Computer says 37-31 is better than 34-29. But I don't understand why. Maybe white broke the tail of 45/40/34 ? ]

32-27 is good move in order to escape chain-lock 18.32-27












23x32 19.27x18 13x22 20.38x18 8-13 21.43-38 13x22












Black has a bad binding (22/24). White 21. 43-38 has a aim to use black bad position. 22.49-43
[ 22.38-32












But 38-32 is good at this moment. White aims 31-27x31 in order to make short wing lock (KVO) in white left wing. 14-20 (22...22-27 23.31x22 17x37 24.26x17 11x22 25.42x31












When black moves this wishing to escape from KVO, black has bad shape after exchange. So it is hard for black to escape from KVO.) 23.31-27 22x31 24.36x27

23.30-25 9-14












White wanted black's 5 pieces in right wing to be freezed with 45-40-34-30. Black has very heavy long wing, so white make it in time. 24.45-40 4-9 25.40-34 9-13 26.34-29

White had a shot using the gap at 18 and 9.
[ >26...21-27












white 42-37 is dangerous.So 21-27 is good. But this black move is very difficult 27.42-37 22-28 28.31x22 13-18 29.22x13 19x8 30.33x22 24x31 31.26x37 17x28 32.43-38 20-24 33.38-33 14-19 34.33x22 3-9 35.44-40 8-13 36.25-20 24-30 37.35x24 19x30 38.40-34 15x24 39.34x25 11-17 40.22x11 6x17 (-0.01;1.65/12) ]
