荣祥 > Step 11th (C8+2)is not realistic move , it ended up wasting step and become attacking pcs.
You idea is to have have left R9=8 being move out but not sucessful.
On Step 31th , can consider C5=7 to force the Black Horse move up or backward . Id move up juz exchange the pcs.
C5=7 Also make adjust of the formation.
Still can make C5=7 on 33 th move.Once your red R 6+2 , your weakness exposed and resulted loss of red 9 Horse.
On 48th move C8=9 , black had already know that he will be able to attack into your formation if you move black R2=3 , he can win a pcs back anytime
