  1. Since there are two answers i can presumably give one of them without spoiling the puzzle!

  4. Oooh, there's a Grimshaw in the set play:

    1...Rd2 2.Re3
    1...Bd2 2.Nd3

    1...N moves 2.Ng6
    1...Rd3 2.Nxd3
    1...Rd4 2.Qe7
    1...R along rank 2.Nd3
    1...Bxf4 2.Qxf4
    1...Be3 2.Rxe3
    1...B along short diagonal 2.Re3
    1...d4 2.Qe7

    So that's the set play. A quick examination reveals that there is, however, no move keeping the set play in place.

  6. Indeed. Puzzle by Alvey, Surrey Weekly Press 1919, taken from (page 23) BP Barnes' Pick Of The Best Chess Problems (Paper Fronts, 1983) which I think I may even have bought in Ilfracombe.

    (The original puzzle was also from that book: page 21, Lipton [version by Jönsson] 1st HM Ring Tourney, Evening News 1958.)
