I realistically don't think you've seen the new breed of electronic chess clocks. They have many many different modes that can add increments before your move, after your move, or operate with a delay that counts off 30 seconds before your time starts decrementing, etc.
It is simple... Give each player 45 minutes on their clocks, and give them a 60 second delay. This is 60 seconds per shot, plus an additional 45 minutes for walking back and forth to hit the clock, racking, + a little extra thinking time.
This sounds like you are giving each player their own timer?
Make it where if a player reaches time control, the delay goes down to 30 seconds per shot. If you use up all your time and go down to 30 seconds per shot, then you better start thinking faster.
I'm about 95% sure this can not be done without resetting the clock, and who's doing this , ?
I know exactly how they work , I have played 5 to 10 games of chess every day I wasn't too sick , for the last 20 years with timers.
I do know what they can do.
I also know what they cannot do, and they cannot make the player push the button, to start his opponents timer,that is where the problem lies.
If like I put in red , you propose to give each player a separate timer , which has a slightly better chance, but many people will still forget and lose on time despite being ahead in the game.
Here's my prediction of what will happen with at least half the matches if the players are in charge of the clocks.{ Probably realistically more like 90%}
Player A will shoot and forget to hit the clock to start Player Bs clock. , {That is how the timers are actually supposed to work} Player B who is a couple of IQ points higher than player A, and just as sneaky , will notice they are still on Player As clock, and go take as long as he feels he can, without arousing player A's suspicion that something is funky in Elizabeth In.
Player A takes his turn again and we repeat about 10 times and all the while player As clock has been running, and player B still has all his time left.
Finally one of the players whos clock has been running the whole time, wakes up and smells the paint, and starts a shitstorm, because his opponents clock hasn't moved, he still probably won't realise it's his fault and will blame it on a faulty clock This will wake up all the other victims and there will be all hell to pay, while they try to find some way to fix it.
Even though in reality there should not be a peep, because the responsibility is on each player to hit the clock, at the end of his inning to start his opponents inning.
That is how they have been used since 1883.
