"Bronstein" clock setting

Subject:   Question about Bronstein clock setting
Forum:   BGonline.org Forums

On my "chess clock" Saitek Competition Pro Game Clock, the factory
Bronstein time settings works as follows:  You get 5 minutes time bank, and
3 seconds/move free. Never mind that the minutes/seconds needs to be
modified for use in a backgammon match, that is no problem.

When you start the clock, if you hit the clock before 3 seconds, you don't
use time from your time bank. So far so good. However, if you let the clock
run out for 5 minutes, you time out. That means you don't get a total of 5
minutes and 3 seconds, you only get 5 minutes in total.

I assume that since these are factory settings, this is the way Bronstein
is supposed to work. But there is some confusion whether you should
actually get 5 minutes and 3 seconds in total.

It appears as though saying "Bronstein Clock settings" is inaccurate for
the way BG clock rules currently work, if what I read here is correct.


    Compensation (delay methods)

    These methods require the use a special clock, called a delay clock.
    There are three main forms which provide compensation for both the time
    lost in physically making a move and to make it such that a player can
    avoid having an ever-decreasing amount of time remaining.

    * Simple delay. When it becomes a player's turn to move, the clock
    waits for the delay period before starting to subtract from the
    player's remaining time. For example, if the delay is five seconds, the
    clock waits for five seconds before counting down. The time is not
    accumulated. If the player moves within the delay period, no time is
    subtracted from his remaining time.

    * Bronstein delay, invented by David Bronstein. Similar to a simple
    delay, but the clock begins counting down immediately upon the
    beginning of a player's turn. When his turn is over, his clock is
    credited with an increase equal to either the delay time or the turn
    duration, whichever is less. For example, if the delay is five seconds
    but the player takes only three seconds to move, the clock decreases
    for 3 seconds and is then credited with 3 seconds when his turn is
    over. Therefore, like the simple delay, no bonus time can accumulate.
    However, unlike a simple delay, the duration of a player's turn cannot
    be longer than the original amount of time that appears on his clock at
    the beginning of his turn.

    * Fischer delay, invented by Bobby Fischer. When it becomes a player's
    turn to move, the delay is added to the player's remaining time. For
    example, if the delay is five seconds and the player has ten minutes
    remaining on his clock, when his clock is activated, he now has ten
    minutes and five seconds remaining. Time can be accumulated, so if the
    player moves within the delay period, his remaining time actually
    increases. This style of time control is common in competitive chess
    (including most FIDE events), as well as on internet chess servers. The
    delay is termed an "increment".

Matt Cohn-Geier  writes:

Yes, "simple delay" (or just "delay") is actually used far more commonly,
in both chess and backgammon tournaments, than Bronstein. Due to
indiscretion in terminology among backgammon players, "Bronstein" has been
taken to mean the same thing as "delay", although there is a difference.

You may have to adjust your clock's settings based on mode but delay is
perhaps easier to set/understand and more common.
