Something a little different this time. White’s aim is to
deliver stalemate on his second move, not the more usual checkmate.
The problem shows a standard problem idea in an economical setting.
Solution: The key, 1.Se7+, gives five variations:
1...Sd3 2.bxc8R; 1...Kc7 2.bxc8B; 1...Ke6 2.bxc8S; 1...Kxe7
2.bxc8Q and 1...Ke8 2.Sxc8. The combination of the four
possible promotions in one problem is known by the German term
Allumwandlung (all the promotions), or AUW for short.
