GM Hu Ronghua's Sandwiched Horse Defense Treatise Chapter 04

In Chapter 4, the GM introduced specifically Red attacking with the 56 Cannons against Black's Sandwiched Horse Defense (SAH)  with Right Elephant Variation. There were three boards which discussed Red attacking with various formations.

• In the first board of Chapter 4, Red attacked with the 56 Cannons Variation and Black developed his left chariot as a ranked chariot.
• In the 2nd board, Red would attack with R8+6.
• In the 3rd board, Red would attack with P5+1! It would be the most complex of the 3 boards in the chapter
