  • Questions for Canadian Open organizers

    RE: Time Controls of 40 moves/90 mins, remaider in 30 min, with 30 sec.
    increments from move 1.

    1. Why not the nearly the same but simpler 120 minutes total, with 30 sec.
    increments, as in the Open section of the Hart House tournament that
    runs the week before?

    2. What would happen if a player forgets to reset their clock from
    the Hart House tournament, oversteps the first control of 40/90,
    but their flag doesn't fall as their clock is allowing all/120.

    Couldn't they just argue that they thought these time controls were
    the same?

    The G/120 time control usually results in longer games, as often, games do not reach the 40th move. The digital clocks should automatically add the additional time to each player's clock at the 40th move.

      I'm not sure I understand the second part of your
      answer Kevin.

      I think you mean that the 30 minutes is added to
      a player's clock once their first 40 moves is played.

      (But they still get 90 + 20 minutes to play their first
      40 moves, yes?)

      I can't see that the time control of all moves in 120
      minutes with 30 second increments but no first control time
      is much inferior to the one stipulated.

      Both controls have 120 minutes for all moves, plus
      30 seconds per move, so their games aren't any
      different in length of time, nor probably in moves.

      The 120 SD will probably have games with more
      time spent on earlier moves and less on later ones.

      My question to the organizers was is the first time
      control worth the extra complexity and potential
      confusion, given there are 2 tournaments within one
      week of each other being run by the same TD,
      with very similar but still different time controls?

        Assume that theoretically, a game lasts for 30 moves, before checkmate is delivered by white (on the 30th move, 59 ply). Black prolonged the conclusion of the game for as long as he could, despite being clearly lost. It is assumed that both players use all of their time, down to the last second. Thus:

        with the 90m + 30s/m time control:

        The additional 30 minute sudden death time control will not come into effect.

        The maximum time consumed would be the sum of the initial time control multiplied by two (to account for both players) plus the number of individual moves (59 in this case) multiplied by 0.5min in order to account for the increment, minus a required one second remaining on each player's clock.

        = 90 min x 2 + 59 x 0.5min - 2/60 min
        = 209.4666 min


        with the 120m + 30s/m time control:

        The maximum time consumed would be the sum of the initial time control multiplied by two (to account for both players) plus the number of individual moves (59 in this case) multiplied by 0.5min in order to account for the increment, minus a required one second remaining on each player's clock.

        = 120 min x 2 + 59 x 0.5min - 2/60 min
        = 269.4666 min

        As you can see, the game could last for an additional hour.

          Although the TC's are similar, this is a FIDE requirement for norms.

            I am not an organizer of this year's Canadian Open, but I was of the last one in Edmonton, so I will try to answer this question since we used the same time control then.

            Essentially, for norm purposes FIDE only allows a few time controls to be used. Game 120 with 30 seconds increment is not one of them. In fact the only time control in one section that is allowed is 90+30 seconds increment, but this is too short.

              Thank you. That makes sense now. Possibly Hart House doesn't see obtaining norms a realistic possibility.

              Kevin, I think we agree that game quality is better, probably why FIDE prefers it.
