Richard, I personally like the short algebraic better and don't use it for any adaptive purposes. Also the notation for pawn moves in the short version doesn't need a P to denote that a pawn moved. A pawn moving to the fifth rank and the forth file could be written as (d5) leaving out the (p). I don't know if this would save much space. Will the letter (p) help when using adaptive technology or is it not needed?

We also have a new format for the problems. I am now including a "algebraic" style problem setup in addition to the FEN as requested by Mike Allain. I am currently including both a short and long version of the algebraic setup. Although it is no additional work as the computer does the formatting, that approach takes a lot of space, so unless someone specifically wants me to keep the long version, I would like to drop the long version. Please post your wishes to the list or me privately. I have also expanded the FEN to include the additional fields. Now you should be able to copy the FEN portion and paste it into a file and save it as a .fen file. That file can then be loaded into your chess engine to get a second opinion! These problems are from Mario Lang's puzzle web page at http://delysid.org:80/chess/epd.cgi and are reported to be from Fred Reinfield's book "Win At Chess" 1958. I am numbering the problems like the web page as WAC1, WAD2 and so on. Each problem is posed as "What is the best next move...", and only the first move is given as an answer. Each is the first move of a combination, though, so we will have to deduce any following moves on our own. We have not had much in the way of list discussion on the problems from Larry Evan's book so I want to ask if anyone has suggested changes. I think the Reinfield problems may be a little more difficult, although this first one is about the same as the others we have been doing. Would this work better and be more educational if list members answered the problems and discussed what principles were at play? I am open to suggestions on any of this as we can always improve our process. Remember the point of this list is to help learn more about chess. So here is the first WAC problem, remember to let me know if you want to keep the long algebraic setup. Problem WAC001: -------------------------------------------------------------------------------- White to move FEN Problem Setup: 2rr3k/ pp3pp1/ 1nnqbN1p/ 3pN3/ 2pP4/ 2P3Q1/ PPB4P/ R4RK1 w - - 0 1 Short Algebraic Problem Setup: White: Kg1, Qg3, Ra1, Rf1, Bc2, Ne5, Nf6, Pa2, Pb2, Pc3, Pd4, Ph2 Black: Kh8, Qd6, Rc8, Rd8, Be6, Nb6, Nc6, Pa7, Pb7, Pc4, Pd5, Pf7, Pg7, Ph6 Long Algebraic Problem Setup: White: King g1 Queen g3 Rooks a1 and f1 Bishop c2 Knights e5 and f6 Pawns a2, b2, c3, d4 and h2 Black: King h8 Queen d6 Rooks c8 and d8 Bishop e6 Knights b6 and c6 Pawns a7, b7, c4, d5, f7, g7 and h6
