This is a really good game to understand the complexity of open-ended opening used by both outstanding players and importance of opening concepts.
[04R] Since Red is a horizontal 6-Rook and no longer protecting Red's right, could moving the Horse to line 4 a better choice? This will form a barrier to Black 8-rook, protect the 3-Soldier and 2-Artillery and most allow the Red Rook to create some havoc while ignoring Red's own right sector. The linked Red Artillery also provide a strong defence when needed to both sides.
[06R] Advancing the 7-Soldier to inconvenient the Black 3-horse might be another option making use of the overcrowding at Black right. If Red Rook can eat the 3-infantry, this 7-Soldier can also advances to add pressure to Black right.
[07R] Look like a opening error which allow black rook control the pawn line and extend control to both Red sectors. This results in success for the cross-palace artillery. Maybe can consider use the left Horse protect the 5-Soldier and then develop Red's left .
[09R] Once Black form the stable Fan-Gong-Ma formation, Red can consider to get ready to develop the slower left section.
[10R] My own choice would be to move the Horse to line-7 instead of line-9. This way I can linked the 2 Horse at line-5 if needed and can also be used faster to add pressure to Black right compared with the 9-Horse. Also because Red don't have 8-Rook to guard line-8. the Black 2-artillery basically has free movement which is risky for Red. One possible variation is
Red's fighting spirit (especially the Red 3-Horse) till the end is something all of us should emulate. Any mental or move weakness by Black in such case will mean a Red Victory or Draw.
A closely fought game till the end. Worthy of its Table 01 status.
