Look at it another way. What was the quality of the win?
Did you play your best or struggle somewhat?
Did you win only because you got several turns at the table due to their bad night?
Not much is talked about the quality of a win. If I win because someone scratched on the 8ball is not of the same quality of win when I make what I refer to as a one mistake player suffer. A one mistake player is someone you play that if you make one mistake, that's it, you are in your chair for a bit.
Last night, in the 8 ball tourney, my first match was with a real inexperience player. I won the match, but it would not be a high quality win because there were a few times I struggled, for no real reason.
In the next match, I would say it was a high quality win because it was against a one mistake player. I had gotten the jitters out of me after the first match and was just stroking away.
So, look at the quality of your win and not worry about their bad night.
