Variant Proof Games by Peter Fayers

External Events & Adds 14 Comments

vpg-pf-ann“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.)

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.759 – Illo 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.758 – Geoff Foster (h#2,5; Back-To-Back). A neutral King in a Back-To-Back problem!
  • (24.03) No.757 – Geoff Foster (h#2,5; Back-To-Back). Three nice mates by Back-To-Back neutral pair in a three-men problem!
  • (24.03) No.756 – Misha 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, 755 – Sébastien 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.753 – Julia 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.

  • (14.03) No.752 – Kjell Widlert (#6; Circe; Maximummer). The eternal Albino theme, with a use of Circe and Maximummer here.
  • (14.03) No.751 – Karol Mlynka (h=2; Face-To-Face; Circe; Phantom Chess). Nice thematic play of the two Pawns!
  • (13.03) No.750 – Julia Vysotska (h#2; Back-To-Back; Take&Make; Lion; Rabbit). A combination of Back-To-Back and Take & Make.
  • (13.03) No.748.1 – Stephen 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.749 – Mike 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!
  • (09.03) No.748 – Stephen Emmerson (h#3; Relegation Chess). One more variation of 100$ theme called “-$60 theme” by the author! 🙂
  • (08.03) No.747 – Gani Ganapathi & S.K.Balasubramanian (h=2; Take & Make). Two pairs of thematic pieces in action!
  • (08.03) No.746 – Aleksey Oganesjan (h#12; White Minimummer; White UltraSchachZwang). A nice journey of the wP and a promoted wQ!
  • (07.03) No.745 – Peter Harris (ser-#7; Royal piece; White Maximummer; Sentinelles Pion Advers; Super-Circe; Chameleon Chess). An exotic mate with 4 fairy conditions and white royal S!
  • (07.03) No.744 – Stephan Dietrich (h#4; Glasgow Chess). A question: if it is still 100$ theme in case of 4 moves with Glasgow chess?
  • (06.03) No.743 – Vlaicu Crișan (4→ser-#2; PWC). Rundlauf of the black King combined with neutral AUW in Miniature!
  • (05.03) No.742 – Sébastien Luce (ser-#16; Anti-Circe). A new interpretation of Albino theme shown in No.725, but this time with a neutral pawn and a neutral Excelsior in Anti-Circe!
  • (05.03) No.740, 741 – Alberto Armeni – two different problems with AUW: No.740 (#2; Anti-Circe); No.741 (PG5,5; Annan Chess).
  • (04.03) No.739 – Tadashi Wakashima (h#2; Invisibles; PAO). A new interesting example of the Invisible(s) piece, that was a theme of 9th Japanese Sake TT, 2009.
  • (01.03) No.738 – Vlaicu Crișan & Andreas Thoma (-20 & #1 Proca Retractor; Anti-Circe). Unusually long interesting Retro-play!
  • (01.03) No.706.1 – Andreas Thoma (-8 & #1 Proca Retractor; Anti-Circe). Improved version of No.706!
