Type A: You were dominated from the start and could never muster any resistance
Type B: You had equal chances and were eventually outplayed late in the middlegame or endgame.
Type C: You almost won, but couldn't find the right continuation to drive the full point home (and ended up losing as a result).
B for me. It least it seems like it in the games I've looked at.
"B" pour moi as well.
I am a mixture of types B and C, but type C, depends on my mood,
type A could be in need of opening pratice? When I started out,
I think it is important to look at all games equally. Take nothing for granted. Yesterday I discovered that I could have won a game one move quicker. I learned to execute a tactic/combination better. It does not seem like much of a point, but maybe with a few seconds on a clock it could mean the difference between a victory and a time loss.
..and I have lost games a full queen up, because failed to win promptly ... losing on time.
I learn from Type A the most...I can just quickly go look up the theoretical move I didn't play which got me into trouble
type C I have a LOT of losses from that....dunno how to minimize these losses though.very often I get this advantage that looks decisive,I desperately look for the knockout blow,can't find it,and blunder somewhere due to time pressure and lose.these losses hurt the most.i'm doing tactical exercises every day to rectify this but I suspect this problem won't entirely go away.
When I was losing all the time, I learned how to avoid getting in bad positions so quickly. But I definitely learn more from my wins now, than my losses.
For me, I tend to learn the least from type C, and more from Type A and B. This is because of my own frustrated ego, where I don't want to even look at games I should have won because they just piss me off. It's a bad habit for sure.
Against better players, I had lots of type A games. For me, these are most frustrating. At the same time, these were also the games that eventually convinced me I needed some serious opening theory study, and I'm thankful for that now. It's simply not true that grasping principles of development are enough to get by for long. In post mortem, I still peruse every single game of mine (even those won) especially regarding to where the first "out of book" move was and if I could do better at that point next time.
