“Some of you may remember that several years ago I was collecting proof games in chess variants with a view to eventual publication.
I now have a round 500, and put the collection on the web for anyone who is interested. Please feel free to view, download, or print (probably not a good idea – it runs to 162 pages. But it is mainly set in 14pt type, suitable for print in “booklet” format.)
Magazine editors and fairy/retro subeditors are invited to broadcast this information to their readership, and everyone is invited to fill in any gaps in the collection. Please send me any proof games I have missed. In English, French or German – I have macros which translate TCFDRP or TSLDKB to RSBQKP, both in the Forsyth and the solution. Enjoy!“

Good effort. Thanks.
very good Anthology of proof games!
just about your last problem in Variant Chess, i think there is a démolition! ( sorry)
Peter Fayers VC 2010
After Black’s 1st,
Superpawns, Glasgow Chess, White Must Check
1 Pb2xg7=S+ Bxg7
but : 1 Ph2xc7=S+ Qxg7 🙁
BTW : I keep this pdf in my favorites :o)
Oops: forget the demolition…
It is an other proof games, I am very badly woken! 🙁
A great achievement, Peter!
Here are my first notes:
2. This problem received 2nd Honorable Mention (judge C.C. Lytton)
3. See P1000389 in PDB. Problem cooked by Gerd Wilts: 1. h4-B a6-B 2. b3-B Ta4-B 3. La3-B Txh4-A 4. Txh4-B Sh6-B 5. Txh6-A a5-A 6. Tg6-B Sa6-B 7. Tg8-A h5-B 8. Txf8-B h4-A 9. Tb8-A h3-B 10. Txc8-B h2-A 11. Tb8-A hxg1=L-B 12. Ld6-A Lh2-A 13. Sa3-B Lxd6-B 14. Db1-B 0-0-B 15. 0-0-0-B Dxb8-B 16. Th1-A Dxb3-A 17. axb3-B Tf4-A 18. Kd1-A Lf8-A 19. Ke1-B Te4+B
It is almost like an encyclopaedia of fairy conditions! It will keep me occupied for several months containing as it does so many beauties! Great!
Very nice Peter!
Should this important project be exhaustive concerning fairy conditions/pieces, or the fact that “variants” are considered is leading to some selection?
If not, and according to WinChloe, here are the missing categories related to my own practice:
Moreover, some “important” works are not quoted, such that the first prize of the Trillon Memorial Tournament (a Backhome PG selected for the Fide Album).
It is purely a collection, not a selection. Every VPG I have seen published is in there, including some not very good ones (some of mine are like that). If it’s been published, has not been cooked, and I can find the solution, then it qualifies.
Which brings me to your list of “missing” variants. I typed stip=’bp’ and k=’lortap’ into pdb, and got 3 results. None of them had solutions!
I’ll try with your other suggestions; any I find that qualify will be in the next volume.
In order to get a full collection, maybe you should buy WinChloe, or be in touched with a composer who owns it – indeed this program contains some problems not quoted in the PDB server.
As an example WinChloe shows 14 not cooked Lortap PGs. Note that the french name is used – Elliuortap (Patrouille reversed, instead of Patrol)
The proof game in your Back Home article here on JF is the only one I’ve seen in this genre, though I have not solved it yet. Is the FIDE problem that you mentioned above on JF somewhere?
The article contains a second Backhome PG example, although not the “Fide” one. Here it is (in French language):

Thanks. I apparently scrolled through this one. Saw the 7
(or 7.5)-mover. With my old phone, I cannot download pdf’s. Need to do that on my desktop PC. Sounds like the coverage on fairy proof games is fairly broad in Fayer’s pdf. I would like to read it.
A FOURfold Schnoebelen, all of them BackHome-motivated! Brilliant.

Thank you very much, Peter! And thank you Paul for a comprehensive review!
Yes, the cook to 288 was known. I did not fix it yet.
