That was a Quick game and looks like you just lost on time. Three games already, but you didn't mention winning a Long game after two moves. What happened there?
That was a 2+0 game, meaning you clock counted down from 2 minutes. You moved slowly and lost--it's easy to get a better position if you use more time than your opponent. 
When you look at seeks, pay attention to the Time field.
"6 0 (blitz)" means your clock begins with 6 minutes on it--that's all you get.
"10 8 (long)" means your clock begins with 10 minutes on it, plus 8 extra seconds are added to your clock every move. This is called an increment.
Thanks likeforests -- you have helped. I will be much more careful. I like to win on the basis of skill -- what do they allow in a masters tournament -- 3 min/move? The game I addressed was not even out of what I would have called the opening segment -- not close to mid-game. I doubt if applying the, I suppose, tactic will ultimately get anyone very far and certainly with any pride.
Again, thank you for some explanation. Although I was not aware of playing a later blitz -- tried to avoid, somehow I ended up with a 1436 blitz rating -- whatever that means on one's first sessions.
First attempt on-line -- Grizzlytae (I believe) won on basis of time -- I haven't a clue how that occurred or if that player somehow received a benefit from the tactic -- it certainly was not on position, and I do not consider myself a slow player by any stretch of the imagination. I believe one piece was exchanged, and I threatened check on the move. I am definitely not accustomed to watching some clock but rather concentrating on the game. Is there some time length expression I should key on? Appreciate any help. Thanks.
