even if it takes you 1move per second i guarantee it is very likely to be checkmated in 60 moves, or in jgls case since he is a beginner i believe someone like RainbowRising can checkmated him in about 25 moves, or at least after 15 moves he will be in a winning position.
A winning position means nothing if you have no time on the clock. I stand by my statement that without premoves, being up a full Queen with 20 seconds left means absolutely nothing if there's no immediate tactical checkmate.
