What is your favorite time control and why?


The first ten or so years I played I neither owned nor used a clock. Playing without a clock is still my favourite way to play.

10/5 and occasionally 15/10
Long enough to think about moves (not too much, though) and also short enough that you don't have to worry about stallers.

3/0 blitz or 1/0 bullet. Allow me to play quick games from my bedroom against strong players including GM's IM's etc.
Rapid 20 mins. As an old guy with memory issues I find 10 mins. too fast for me, 30 mins. I will loose interest in the game.
