HOMEBASE (aka: "AT HOME") PROOF GAMES
In this sub-genre of Shortest Proof Games, all surviving units appear on their apparent starting squares.
In chess compositions, "silence is golden". This means that the diagram should do the talking, rather than a lengthy stipulation (or a lengthy commentary like this... :-) ). But in Homebase PGs, the diagrams are silent too! Austere and cold, only the gaps in the ranks tell to those who would bend an ear the sad yet hauntingly beautiful stories of what has unfolded on the board... heh.
So on this page are some "homebase" problems, mostly by me except where noted. I have also collected on another page all prior work I could find by other composers in this area. I would ideally like to collect all the world's homebase PGs here. ("All your homebases are belong to us!")
If you solve some of the problems on these pages, you may see that there is one particular task which adapts itself particularly well to the homebase form...
I also wondered how many "homebase" positions there are of minimum length (4.0) and have collected them all on another page again.

Finally, as a bonus, can you find the unique "homebase" Illegal
