Variant Proof Games by Peter Fayers

vpg-pf-annSome 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.)

http://www.jsbeasley.co.uk/vchess/peterfayers.pdf

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!

  • (25.03) No.759Illo Krampis (h#3; Grasshopper, Berolina-Pawn). Light problem on the theme of Superproblem’s TT-131 (сyclic shift of guards). Warm welcome to Illo in Original problems section of JF! I’m happy to meet and introduce to you a new Latvian fairy composer!
  • (25.03) No.758Geoff Foster (h#2,5; Back-To-Back). A neutral King in a Back-To-Back problem!
  • (24.03) No.757Geoff Foster (h#2,5; Back-To-Back). Three nice mates by Back-To-Back neutral pair in a three-men problem!
  • (24.03) No.756Misha Shapiro (h#2; Gnu). Gnu-promotions + black pins after white Annihilation captures! Warm welcome to Misha in Original problems section of JF!
  • (23.03) No.754, 755Sébastien Luce – Non-standard implementation of castling in two different problems! No.754 (h#10.5; Black UltraSchachZwang); No.755 (h#2.5; Circe RexInclusive; Kamikaze RexInclusive; Duplex).
  • (22.03) No.753Julia Vysotska (h#2; Back-To-Back; Take & Make). Back-To-Back specific pin of the mating neutral piece! Hopefully, shown for the first time. 🙂 I should admit, that the solutions might look weird here and the interpretation of neutrals’ behavior with Back-To-Back can be a topic of some discussions. Myself, I find such interpretation reasonable.

  • (13.03) No.748.1Stephen Emmerson (h#3; Relegation Chess). A new version to No.748, commented by the author as “In both settings, the dual choice Se6/Sf7 is avoided by check to the wK, but thanks to James Quah, with wKd8 it needs the Relegation rule for the avoidance to work. (BR prevents new cooks).
  • (11.03) No.749Mike Neumeier (ser-h=8 / Pser-h=11; Royal piece; Grasshopper). A nonstandard way to the well known (classic) stalemate finals! Warm welcome to Mike in Original problems section of JF!

  • (07.03) No.744Stephan Dietrich (h#4; Glasgow Chess). A question: if it is still 100$ theme in case of 4 moves with Glasgow chess?
