Aganju: That is not how it works. The system records the times in both of your games in your records as if the game occurs between two players in the same time zone.

Next time that an opponent of yours plays a move in a game of yours, check out the clock in the upper right of your screen and then click on that game and you will see that it was played only a few seconds earlier, regardless of which time zone your opponent was playing in.

It is not just the 18 hours bonus, you know. It does not look like a bug to me.

O čem je toďten plk: Re: Fischer's clock
ThunderGr: Time limits are way too generous here, it's a bit of a joke. Some players wait until the very last moment before time-out to make a move, it's really quite sad. As far as I'm concerned slow players kill game websites, they suck all the enjoyment out of the games, makes everyone lose interest after a while. There are more and more of these guys here on Brainking (I'm not naming names but I'm itching to!). I have my own theory as to why.

moistfinger: Maybe so, but, if I am not mistaken, the 3rd number in the fischer clock indicates the *absolute limit* of the game. That is, despite of what the other 2 numbers say, the game cannot exceed the *total* of the 3rd number. So, a game with a 30 days limit will end at the 30th day, no matter who's turn is to move at that time.

"Let's look at an example of a player's time usage (and his corresponding clock display) across the first few moves of a 40/20 Fischer increment game.

The White player at the start of such a game has "40:00" showing on his digital clock, which means that he starts with forty minutes in which to make all his moves. Black hits his button to start White's clock (and to start the game). White already knows what he wants to play, makes the move 1.e4, and hits his clock to complete his move. Three seconds have elapsed between the time Black hit his clock to begin White's move and White hitting his clock to end the move.

In a traditional "sudden death" game, White's clock would read "39:57" (showing that three seconds had been used) and that would be it. But since this is a "Fischer" time control game with a twenty second increment, the digital clock has been pre-programmed to add twenty seconds back to a player's time whenever his button is pushed. Thus twenty seconds gets added to White's clock when he presses the button to finish his move, and the timer's display now reads "40:17" (his initial 40 minutes - the 3 seconds he took to move + the 20 "bonus" seconds of the added increment):

40:00 - 0:03 = 39:57
39:57 + 0:20 = 40:17


Black plays 1...e5 and hits his clock to end his move and start White's timer. The White player snaps off 2.Nf3, again taking three seconds to make his move and hit the button on his timer:

40:17 - 0:03 = 40:14
40:14 + 0:20 = 40:34


...and so White has actually gained 34 seconds since the game's start because he's playing pretty quickly.

Black bangs out 2...Nc6 and hits his clock. The White player already knows he wants to play a Ruy Lopez and plays 3.Bb5, again taking three seconds to make his move and hit his clock:

40:34 - 0:03 = 40:31
40:31 + 0:20 = 40:51


White's picked up nearly a full minute - he now has nearly 41 minutes to make all the rest of his moves.

But Black has other ideas; either by design or by accident, he doesn't play the standard Ruy reply of 3...a6 and instead plays 3...Nf6. This throws White for a bit of a loop as he hasn't prepared for this move. He eventually figures out a reply but takes a full two minutes and thirty-four seconds to think, make the move, and hit the button on his clock:

40:51 - 2:34 = 38:17
38:17 + 0:20 = 38:37


...and White now has 38 minutes and 37 seconds left on his clock to make all of his moves before he'd "lose on time".

I've played quite a few online games using the "40/20" Fischer increment and discovered that, on average, each player usually uses about an hour to play; this is a good increment to use when you have about two hours to play a game. For a faster game you could easily start with a shorter "sudden death" time or a shorter increment (or both, such as "20/10": twenty initial minutes with ten seconds added each move). A few algebraic equations have been published which let you approximate the time a game will take when using a particular Fischer time control; although it's impossible to predict infallibly the length of time which a (theoretically) open-ended game will take, these equations can at least give players a "ballpark" idea of the expected duration of a game.

Fischer increments were officially recognized by the United States Chess Federation for tournament use starting in the mid 1990's. This caused a fair amount of contoversy at the time since players had to replace their analog clocks with (then more expensive) digital models. That initial furor has died down over time, but you'll see many players still using their analog clocks for casual "sudden death" games at chess clubs or between rounds at chess tournaments. (In fact, an analog clock is still my choice for "speed" games with my friends and family, since anyone can understand how to set and use one without any special instructions.)"  


In BrainKing we have 3 parts of Fischer's clock - A/B/C:
A - time for move (on the beginning of game)
B - time added after each move
C - maximum time for one move

Example #1 -> 30days/1day/30days

Games started at 8am. Your move at 9am
30 days - 1 hour + 1 day -> 30 days (because in C we have 30 days)

Example #2 -> 21days / 18hours / 31days 23 hours

Player X - dead time at 5pm, moved at 4:40pm (20 minuts before dead line)
20 minuts + 18 hours -> 18 hours 20 minuts
