No.374 by Neal Turner – A very seldom fairy combination – SAT with Royal Grasshoppers – in s#!  (JV)


Definitions:

SAT: A King is under check if it can move to only one square not controlled by the opposite side.

Grasshopper(G): Moves along Q-lines over another unit of either color to the square immediately beyond that unit. A capture may be made on arrival, but the hurdle is not affected.

    The problem seems very interesting and I believe that it’s indeed interesting.
    The explanation seems good and I believe it’s indeed good.
    The definition of SAT seems clear and simple but I don’t believe that it’s clear. I tried the other source but that only additionally blurred my faint idea of SAT.
    I’ll try again tomorow 🙂

      You’re right, Nikola, the definition is more like my understanding and it is really unclear! 🙂
      Another one (from StrateGems) is: SAT – A King is in check only if he can move on an unattacked square.
      Is this one better?

  2. Neal Turner says:

    Yes, the definition of SAT can be perplexing.
    My own working definition is simply:
    ‘A king is in check if any of its flight squares are unguarded by opposing pieces.’
    I’m not sure if this can be derived from the ‘official’ definition in the strict sense, but it seems to serve adequately and is certainly less confusing.
