I was lucky more than once this game. It looks like white could have won with |9.s17 which threatens white M16. For example 10.p16 11.r15 or 10.q16 11.r14 12.r17 13.q18 14.t16 15.m16 So, I probably should have played |8.l18 or |8.l16.

16.R18 was very hasty of me although it might still be winning. |16.p13 would have been much better because it still wins on the right and it threatens black N12.

One possible variation at the end was |23.h20 24.i22 25.k21 26.l21 27.m20 28.j22 29.o19 30.p13
