* Move 12th , Black E3+5 can consider black C2+4 follow by C2.3 or E3+5
[Reply] If Red didn't A4+5, a workable variation is P5+1, c2+4, P5+1, a4+5, P5=6, e3+5, A4+5 and prepare to H7+5 in the next step. A4+5 is just a change of sequence. If Black c2+4, Red will P5+1.
I guess that black didn't want to go into an opening she felt too chaotic. e3+5 is a good option then.
I also think black can r8+5 instead of c2=7 at move 16.
* 24th Move 14th Black C8+2 , can consider C8-1 , force the red horse to red H6+7. anf follow by black 1.3
[Reply] Yes. c8+2 looks good but was soft. Move 23 Red doesn't need to H3-1, say C9+1, h3-5, H6+5, p7+1, R8-4!?
* 26th Move red C5.7 is a good move to make win of this game.
Black might missed the chance by moving black R8+4.
may be can consider Move 26th black C1.3 and follow by black R8+4 , worse case still can black R8.4 or R2.1
[Reply] C5=7 was wrong because black can still c8-3! Therefore Red should have C9+1 first.
Move 28 black seems have to h7-5, not quite bad yet. Move 34 p7+1 was too greedy. e5-3 is better, afterward C9-2, h5+6, black can still struggle.
Move 38, black missed the last chance to play e5-3 and lost. Had black e5-3, C9-2, h5+4, R8=3, h7+6, R3+6, h6-5, Red is in overall advantage, but black still has chances in a complicated situation.
