炮8+5就优势了。如车3+1,炮2平1,车3平2(or马3进2),车1平2 red is clearly better.
Move25 相3进5 (with the plan of 炮1退1 but no obvious target) is also a clear mistake, should die die 马3进4. Should black 车7进1 then 马4进6, 车7平4, 马6进4. Else lose pawns lose 兵种。
Move31 炮1平3 also no good. Should eat. 炮 1st file better than 3 file.
I'm not saying Lu Guo Long no good. But this round, Hong Quan Fa can play better than him. Once in a blue moon situation. Haha. No offence.
