i feel that che9+1 is not very good the movement of the car is abit slow and might be taken advantage. Consider pao 89 should be better. red's pawn 3 + 1 also has abit of a problem as well should move che9+1 instead.
i have slightly different views from ji3du4
i feel that the more important move lies in move 7. sacrificing the Pawn 5 + 1 has some problems. Should pao 5 + 4 , If red che 63, black ma7+5 blacks pieces move out quickly black is slightly better.
i feel that if move 10 black che 96, red pao87, blackma5+6, red ma9-7! (think black faces abit of a problem.) (if black pao 8 + 1, red che6 + 1)( if ma3+5, red pao74, black ma5+6,red pao24!)
But i do think that move 7 che6+3 is better than the game played
