The clock is part of the strategy. It's called flagging. You can have a terrible position but if you're opponent poorly managed his time and you win because his/her clock ran out that's not your problem. Take their elo with pride chess is a battlefield.
Blitz Timeout

Nope. You'll learn to appreciate the art of flagging eventually (or maybe not?)
The thing is the clock is also a piece. And technically if you still have a piece you can win or at the very least draw.... so if you're in a lost position, but have more time on the clock chances are your opponent only has a better position because he spent more time on his moves, so that's on him for managing it poorly, not your fault. And now they have to move fast and that increases their chances of blundering (just like you likely blundered for moving fast and got into a worse position). Their position might be better, but they still have to prove it.

Over the last 7 days, I have lost a whopping 46% of my games by being flagged, many in winning positions. Maybe I achieved those positions because of my clock usage. I spend my games trying to learn rather than win.
Less often, I have flagged others when they were in winning positions. A portion of those were when I was close to losing on time myself. I did that to learn how to better flag others when necessary in competition.
The clock is part of the game. Accept it.
If you have clearly lost a game but your opponent is short on time, is it poor form to continue play to get a win by timeout (it feels terrible), or is it important to play the clock as part of the whole Blitz format?
