Alternate Mating

  • #1

    I played a game and won, but the computer analysis gave what it called a "faster mate" even though (unless I'm missing something) it was the same number of moves, and "a better move," even though both sequences were forced - go figure. But I found it curious that I never even considered the computer's more direct sequence of moves.

    Both moves are equally good.  Your choice is prettier. 

  • #3
    Your sequence was 1 move longer than the computer’s.

    2....Qxg3 3. Qg2 Rf1+ 4. Qxf1 Qh2#
    2....Qf1+  3. Kh2 Qxh3+ 4. Kg1 Rf1#

    The problem is your opponent didn’t play best defense. Your opponent made a mistake after qxg3 and played qg2. That is the only reason your sequence ended up being the same amount of moves as the computers best sequence 1 line before. Had your opponent found Bg2 instead of Qg2, you would see why your move was “inferior.” Just telling it to u the way I see it by computer analysis. But still a nice mate.

    Bg2 Qh2#

    3. Qf2! seems to hold on for an extra move

  • #8
    My apologies I meant bishop d3 or bishop f3. They both delay the mate by 1 move. Your opponent playing qg2 turned it into a mate in 2 whereas Bd3 or Bf3 both led to a mate in 3.

    When you are comparing your moves to a computer’s make sure your opponent is playing the best defense. In other words, open the game with “self analysis” and look what happens when he moves his piece. If mate in 3 becomes mate in 2 after HIS move, then he played inaccurately. It is only when the mate count drops on your move that the game is being played accurately on both sides. I can see why the confusion took place. Although it was “inaccurate” on his part, the engine won’t flag an inaccuracy considering the mate was still forced. However it will still flag you for not playing the “most accurate mate”. Whatever, it was still a nice mate.

    I see.  Now that I look closer 3. Bf5 would also hold for a bit longer.  Thanks.

    I like the rook sac

    No problem, definitely didn’t want to sound like an annoying engine enthusiast just hope I cleared up any confusion :) happy to help

    Actually I was confused by the analysis.  The computer line was clearly better.

    I thought that topic was going to be something else.
