KILL THE WHOLE BOARD after sacrificing 73(!!!) stones ⚔️⚔️⚔️⚔️⚔️ (Gokyo Shumyo 7-46) (White to Play)

This is a fascinating classic whole-board killing challenge! It is a perfect practice for recognizing real eye and fake eye patterns and for calculating what happens after your opponent captures a large number of stones.
Try playing this out on your own board and see how sacrificing 73 stones will lead to white's success!
Gokyo Shumyo (碁経衆妙), or "Brilliancies from Go Classics", is a famous collection of 520 Go problems, compiled in 1812 by the Japanese player Hayashi Genbi. This collection, with 7 sections, offers excellent practice for amateur players.
This problem is part of a playlist/chapter where I explain all 46 problems in Section 7 (Miscellaneous).
Techniques in this section include wedge, play inside, connect, cut, and ladder. The patterns are highly valuable, making for a great group of practice!
