This move must be 'Decision'. I think black27 seems not to be proper for Flankaanval.

Computer estimates +0.13. It says that 31-26 is good.

10.31-26 11-16 11.36-31














Computer estimates +0.16. It recommends 36-31, too. Mr Yambe's move is good.

7-11 12.41-36
[ 12.31-27














Computer estimates ;0.18. But I can't understand why. Black can escap from this lock.

[ 13.31-27














Computer recommends 31-27.

18-22 14.27x18 12x23














Black has 'Classic' in his left side and black is ready for flankaanval in his right side. I think his right is slightly heay.
Computer estimates +0.08 at this moment.
