I would also like an option for removing the max time. As other’s have said, the idea that the games will be too long without a max time stems from the fact that we generally use “too long” increments. You can’t convert a byo-yomi of 30 seconds to a +30 seconds Fischer increment, that will give you a much longer game; something like +10 seconds would be more comparable.
For an example of Fischer working great in practice for go, just look at GoQuest: the time settings are 3 minutes + 1 seconds (no max time). 1 second may sound like nothing, but it’s enough that I’m never forced to lose on time.
So why would I care about removing the max time for these short time controls? Even if I could always set the max time high enough that it doesn’t effect the game (right now even this isn’t always possible, since the options are limited by whether you’ve chosen live, blitz or correspondence), having an extra parameter that doesn’t affect the game (like 3 min + 1 sec max 1 hour) looks very ugly to me, and it’s also potentially confusing for the person accepting the challenge. What’s so great about Fischer is how simple it is compared to Byo-yomi, having a max time needlessly complicates it! So having an option to disable the max time completely would be very much appreciated
(This is a minor thing, so I completely understand that it’s not a priority; just wanted to voice my support for the cause )
Edit: Also like SoDesuNe said, the fact that there’s never a max time in chess should surely be a reason for us to at least support that way of playing, so that more new players can feel at home with the time controls. Probably a much stronger argument than my silly personal preferences
