Internet is a funny place.
I never won on time in an OTB.
People should learn that 10 seconds in a Blitzgame can be more than a pawn or even a piece.
And we are speaking about a blitzgame here.
1,3 or 5 minute games means nothing other than you lose(draw) when your time is over. So now i told you the big secret about blitzgames.
You don´t deserve the win, when you have a huge advantage and can´t deliver checkmate in 1,3 or 5 minutes, that´s all.
You invested to much time to get to your huge advantage, you were to greedy.
If you lack on technique to promote a pawn in technical endgames, you also don´t deserve the win. etc.
Guess somebody got a warning and impatient afterwards.
