[utibivjn] Chess time handicap rating

Create a chess rating system designed to provide equalizing time handicaps between differently rated players.  It might have more than 1 parameter and a complicated formula.

Made useful by improvements in technology: easily available chess clocks (e.g., app on smartphone) are only recently available, as well as online play with clocks built into the software.  Elo would not have imagined this.

Resembles how amateur go 囲碁 ranks are designed around stone handicaps, allowing players of different strengths to easily play one another.

Incidentally, professional go 囲碁 games are never played with stone handicaps, so professional go 囲碁 ranks ought to switch to something like the Elo rating system, perhaps with titles (or ranks) based on rating.
