    Who's turn is it?

    That's your task; figure out whose turn it is.

    Blacks mates

    Are you sure it has to be Black's turn?

  • #6

    If you're asking in a problem who's to move, there must be a well-defined answer. If I can arrange it such that it's black to move, it therefore must be black to move. (Proof by smart-alec logic.)

     

    I jest, of course. There is a way to prove it properly.

    No, you're reasoning it wrong. This problem appears on a magazine, so it cannot be cooked. Then you may follow with your reasoning. :P

    This is always true. Especially so for my originals.

    It is so true that the new Android app double-posted it.

    There really are many variations of this puzzle. The concept is the ability to lose a tempo (you can also add moves like a3/h6 etc). So now, the solution should be obvious. Or at least more so.

    Yes, no pieces can triangulate
