Ten, but only due to enormous self-control. Last time it got up to 82, then I got a life and lost them all on timeouts. I'm trying not to do either half of that again, I want to keep it to where I can manage the games without making it take hours a day, even if that is what I like to spend playing chess some days.
Also trying to redirect a bit of my chess energy to OTB and study. And maybe to non-chess pursuits as well.😕
I used to have only 20, then as another person pointed out some of the players on this site juggle several hundred. I'm up in the 60s now trying a heavier load, so far it works, but have a safety net that half my games are 7/7 which gives me more time towards the end of the week as things pick up.
