    I like this light problem! The double check done 3 times with a BTB pair nS/nQ: one check by nQ and another one by nS in the role of Q. For the Black, escaping with nS won’t defence from the mate by nQ, but all possible moves of the nQ in the role of S would give an illegal selfcheck again.

    Supreme elegance, bravo!
    How might it be called, a “BTB+anti-BTB selfcheck-incarceration”?
    BTB effect determines whereto nQ might move but then, the cesser of BTB effect would cause a selfcheck.

    If anyone is ever to write a treatise on the combined elements of Neutrals+BTB, this example should go in there. A succint demonstration, with beautiful three-solution echo. Funny, too (KxnQ is no defense)!

    Well said, Mike! Appears to be the best definition for BTB. Even I can understand it without any confusion!
