14.m12 was a bad idea. I think 14.k11 prevents 15.h9

I survive to 25.s16 and screw up with 26.p15. 26.q12 looks better by far.

27.r13 cuts off top right, so then I messed up lower right with 28.r20 instead of 28.s19

Then I get a break, 30.q11 31.q10 32.r7 33.r8 34.q5 35.m6 36.o10 so the battle shifts back to lower left quad and I made it complicated with 38.f21 where 38.f17 would have simplified things.

Finally, 46.122 would have made my life miserable.

46.l20 not 122

Good Grief... I cannot type. 40.h17 41.h16 42.e23 43.n10 44.s10 45.j21 46.i22 47.l20 would have been difficult

35 m6 was the mistake leading to a defeat. if i had played 35 o7 i probably had won.

The bot agrees that |35.o7 is crushing for white, and M6 was the final losing move of the game.

Earlier, R20 was a losing move by black, and |28.s19 would have won.
