Dilemma

I recently won two game due to a timeout of my opponent. While winning is in general a good thing it is still a difference to me if I win by playing good or being lucky by having a opponent who looses on time. Winning by timeout always leads to mixed feeling. On one hand it is a clear strike according to the rules of the game everybody agreed on by joining a match. on the other hand it doesn't feel like a real win as I haven't beaten the opponent  but time has.
