After writing an article about the "death" of mechanical clocks, I thought it only appropriate to announce their continued longevity. Now that USCF has added the "Blitz Rating" there will be time controls that use no delay. In fact the longest time control will be G/10;d0 (10 minutes - no delay). The shortest time control is G3;d2 and any combination of minutes plus delay that does not exceed 10 is permissible. Examples: G5;d5, G7;d3, G5;d0, and so on.
While mechanical clocks may be passe, watching a flag fall will still stir the passion in the hearts of old timers.
I'd be remiss if I didn't mention that your mechanical clocks can be used in cooking. Set the clock for how long you like your steaks grilled per side and punch the clock when you flip it over! Or - boil for 5 minutes, reduce heat and simmer for two minutes.
