Classical time control ranges from 8 to 300 min. All other clubs and chess federations would consider 8 min as Rapid or Blitz though. But it seems best to create the missing Rapid category instead of just moving up this limit. After gathering lots of opinions on the matter (in other posts), I have created a final voting poll with illustrative images. Take a look !
To read before voting:
Well, people who like longer time controls can just play them, such as 15+15 or the popular 45+45 team league, and sticking to that choice will show their strength at such longer games (most are stronger). Ok, but then, after spending so many days playing for hours to establish that new level, participating in a single 10+0 tournament is enough to wash away this change.
By introducing the Rapid category for those faster games, we will create different polls of players for Rapid/Classical categories. Classical ratings will then be more stable and closer. While Rapid should hold about 90% of the games and still peak to 2700+ (as we see now), any longer time category won't peak so much. Also, the longer will probably not have a top-10 leader-board, to avoid encouragement of cheating, but may have a rating stats chart.
To improve things even further, I suggested adding the Slow category too (better name suggestions are welcome), making it Rapid/Slow/Classical. The Slow range would then hold games 3 times longer than Rapid games, still leaving as Classical the much longer ones like 45n+45s team league games (equivalent to 75m), or the rare 60m+30s (equivalent to 80m) that we see sometimes. Initially, the idea of splitting in 30 min was the most popular. But then it doesn't leave much space for a tri-split (Rapid/Slow/Classical), since the second split would have to be around 90m and it is extremely rare to see such time control to be used online. As a result, I suggested to start Slow at 25 min (which would include popular 15m+15s), and start Classical at 75m (which would include 45m+45s).
Now please vote. Thanks !
