    I wouldn't call this puzzle easy. It took me a few minutes to get it and I play OTB strength of 2200+

  • #282

    What if black  moves KF1 during  checks? Can he possibly win or draw?

  • #283

    There's a very similar puzzle that goes in the opposite direction

  • #284

    Nice one!

    Not quite...

    2...Kf1 3.Qe3 (Qe7 works too) g1=N and there is no immediate mate here.

    Nice one. Requires some visualization and understanding. You need to see the idea of bootstrapping the queen along the a8-h1 diagonal:  1 Qa8 Kg1 (forced) 2 Qa7 Kh1 (if 2...Kf1 3 Qe3! and it is mate next move: 3...g1 4 Qe2# or 3...h1 4Q Qe1# this is a key line that is tough to see). 3 Qb7 Kg1 4 Qb6 Kh1 (the above sideline still applies) 5 Qc6 Kg1 6 Qc5 Kh1 7 Qd5 Kg1 8 Qd4 Kh1 9 Qe4 Kg1 (you had to see that white can mate on e1) 10 Qe1#

    Anytime black plays Kf1 and white responds Qe3 then black can prevent immediate mate with g1=N.  Of couse white then has a non-puzzle caliber win, but it does take a little technique.

    Nope.  White still wins but it takes longer than the puzzle line.

    I thought that at first. But then the black pawn moves to the last square and gets promoted, which forces a queen exchange so that the last black pawn get get promoted and black then wins.

  • #295

    why did the white king not step forward and deliver the checkmate from the queen?

  • #296

    the second black move should be kf1
    then white will win after 42 moves
    bad puzzle

    So kc2, kd2, ke2 is checkmate in one

     

    but okay 🤘🏽

  • #299
    I don't understand, isn't Kd2 just checkmate in the first place?

    But the white king always sees Mr. Copperhead twice, and so he says to himself: "Don't drink and drive!"
