Great minds think alike.
Frequently I prefer to apply common sense rather than the letter of any rule. In addition, I often find it more interesting to discuss what a rule ought to be, rather than what it is literally, right down to its rigid (and sometimes absurd) tunnel-vision conclusion.
It would be ridiculous, for example, to have a rule that would absolutely forbid any player, under any circumstances, from making a move before his opponent has pressed his clock. For one thing, that would allow too much gaming of the system. For example, player X might even deliberately fail to press his clock, so that when Y eventually moves, X can demand a penalty.
At the opposite extreme, it seems obvious to me that each player should be entitled to a clock press, whether blitz or not, as long as he avails himself of that opportunity within a reasonable time.
This would mean, for example, that if white blitzes out a move before black has completed his previous move (i.e. before black has pressed his clock), then black should still be allowed to press his clock, and if he does, white needs to remain alert to this possibility so that he, too, can press the clock appropriately.
Between the extremes, the question may be, how does one write the rule so that it’s fair to both players?
Not joking. In fact, I seem to recall reading, in a recent thread, that FIDE has endorsed this exact procedure, at least in certain cases where the opponent has failed to press his clock.
Under certain circumstances, this “creativity” makes a lot of sense. For example, what if there is a 30-second increment? If one player fails to press his clock, and his opponent eventually plays his move anyway, then both players have been deprived of their 30-second increment. It’s possible the first player “forgot” on purpose, figuring that the loss of the increment would harm his opponent more than himself. This is another example of how one player’s attempt to game the system can be rendered ineffective by an opponent who has a logical, simple, and legal recourse.
