I think less-than-5 minutes games are an insult to Chess. What do you think ?
They may not be chess, strictly speaking, but they aren't worthless, either. Being a time pressure addict on OTB chess I have gained quite a bit by playing 3 and 5 minutes blitz (although blitz is certainly enough not my strong point, I like to blunder a lot).
OTB means over the board games !
Learn to play fast chess. Maybe you will learn to value it then.
