... more generally, when I look at my losing streaks, they usually start with one genuine hard-fought loss against a better player (see, I'm a bad loser!) followed by a mixture of early-resignations, extremely careless blunder-fests, and draws offered when I had mate in 1 because I didn't think I deserved to win. This isn't great. But it makes the point that the thing holding me back is psychology more than chess.
I go through phases. I will get despondent and self-destructive, and play terribly or resign early, and have a huge string of losses. Then I pull myself together and play as best I can, and get a long string of wins. It's not cheating, it's just being a bit of a psychological mess when it comes to competitive games, and I can only apologise and say I'm working on it!
So you're saying you analyzed it after my post and before your reply, and not before that, at the end of the game, before you posted confidently that you'd been "decisively out-played"?
I'm sorry, I can't understand why it takes any analysis to see that end position is even / white advantage +1, to a player who played it.
I think what I meant by "outplayed" was that I couldn't find a single weakness in my opponent's play, and couldn't see any way I could possibly win. I still can't, but looking more calmly now, I can also see that my opponent has equally no obvious way to win, and I had no obvious weaknesses to exploit. The game was totally balanced, and I could reasonably have offered a draw. But resigning in a huff was bad behaviour on my part.
