Sorry a bit blur. It should be R6=4, h8-7.
胡海宇对许升>> If say Black H8-7 ...
Red will be better ...
Simply move R4+1 (Black C9+1)or Red H7+6 or Red C8+4 also much better.
Also found that move 29th ( red H1+2) no good.
Can move Red C8+5 and follow by C8=4 .
You can find black horse is trap no matter black move R1.2 or R9+1
