GM Hu Ronghua's Sandwiched Horse Defense Treatise Chapter 03
In Chapter 3, the GM introduced the SAH with Right Elephant Variation. There were three boards which discussed Red attacking with various formations.
- In the first board, Red attacked with the 57 cannons and one of the sub-variations was Red sacrificing bother pawns.
- Red would attack with C8+4 in the 2nd board.
- Red would use the ranked and filed chariot in the 3rd board.
