    A known theoretical win for White. Next!

    This one is better.


    Your one is only mate in 30.

    why better? Just get the bishop out of the way, and with perhaps a few moves more we have the same. Is more moves = better?

    Ah yes, with black to play I think it's a draw

    How about this one?

    How about this one?
    Assuming white has the move (otherwise Rd8+ draws) it is a standard win for white. I would start with Qf7 or Qe7 to 'split' the board for the black king in 2, reducing the options. But I am sure there are many good first moves.

    I think he means that, requiring 33 moves, this is the longest shortest mate with B+N+K vs. K

    Only 99.51% of these positions are won with White to move.
    Can you construct a drawn position with White to move?

    White should play Qe7+, Qh7+, Qf7, or Qa2, mating in 33 moves. All other moves are inferior.

    But this position is not the longest shortest mate with K+Q vs. K+R.

    That is possible. Only, the technique I use is based on a) limiting the playground for the king, b) driving king and rook apart, c) forcing the king to the rim and towards a corner and finally d) using mating threads, provoke forkings and win the rook. It may not lead to the fastes way in all positions, but will not be off by more than 5 moves, safely within the 50.

    I was referring to the position, not your peerless technique.
