I do that too! Except on my main account......

Strangely, I started feeling the same way as Shaddy recently. I started hating losing but probably for a different reason.

I think the reason is that the way I perceive the game has changed. Go has a special character which is not so strong in other games like chess, backgammon, bridge, etc. Every move says something. If you perceive the game like that, then an opponents overplay, (or e.g. an impossible invasion try) seems to say "I think you are weak enough to let me get away with this overplay".

In backgammon, an overplay would mean more something like "I feel lucky". In chess, the thinking is in a way more analytical, of course the moves have meaning but they don't "speak" as strongly as in Go.

If an opponent tells me that I am weak enough to allow him this or that invasion to succeed, I started perceiving it a kind of humiliation. And in the end if he can get away with it, this makes me feel less well. I hope it's just a temporary situation.

- Thoughts running through my head at point like that are more like: "Looks like the hunting season just started!" I love unreasonable invasions.

And how do you feel when they live when you are pretty sure they shouldn't?

Perhaps you could tell yourself that your opponent doesn't know what his words mean? There are deliberate overplays, but more often, your opponent doesn't know he's saying your weak. He's just choosing the best play he can find.

I admit I get into this mindset sometimes, and I like the characterization of certain moves as "offensive" . I usually take some time to stretch and talk myself out of this mindset. I find I play my best when my thoughts are "live, die, or kill, what can I learn from this?"

Also, I've been on the other end of this. While I've gotten away with vulgar/offensive moves before (not my style), I suspect that some players act as if my moves are offensive when they aren't; so perhaps I do the same thing sometimes--my opponent wasn't really being offensive, but just saw a weakness I didn't.

Another thing--about 70-80% of the time, if an invasion really is offensive, I don't have to kill it. But I won't see that if I'm too busy being offended.

- See the difference is that I don't hold expectations. I'm thinking about stealing base, or preventing access to center as general strategy. Even the opening chapter of Attack & Defense book discusses that goal of killing is unreasonable. I regard this game as intellectual play rather than straight-faced competition. Maybe this is why I find it hard to empathize with OP.

This is of course possible. Sometimes I am not sure whether my opponent is aware of what is going on, or maybe I am completely out of tune myself. On the other hand, I am absolutely sure that I also play such overplays myself without noticing it.
But this consideration still doesn't change my perception during the game.

Before, I used to see the each move as a puzzle to be solved, rather than seeing the whole game as a competition. I don't know what happened but recently my perception has annoyingly changed and this incredibly reduces the fun of playing. Maybe it is time to give a break but the game is like cigarettes, in the sense that you cannot stop so easily even temporarily.

My old teacher ONLY had a drunk account...

Reminds me of a joke:

A young woman walking down the street noticed a little old man rocking in a chair on his porch. She called out to him as she passed. "Hello there! I couldn't help but notice how happy you look. What's your secret for a long happy life?"
"I smoke three packs of cigarettes a day," he replied. "I also drink a case of whiskey a week, eat nothing but fast food, and never exercise."
"Wow!" The woman was amazed. "How old are you?" she asked.
"Twenty-six," he replied.

I feel much the same way as entropi, except that I don't care all that much whether I win or lose: what bothers me is the constant feeling of being out of my depth, and it doesn't really help that my opponent is even more out of his/her depth than I am. This consciousness of my own ineptitude seems to be less of a problem in chess, though I'm not very strong at chess either. Whatever the reason, I find it so discouraging that I don't play much any more. Which is of course a vicious circle, because you're never going to improve if you don't play.

It's good to feel out of your depth. If you don't feel out of your depth you probably aren't playing an opponent appropriate to your level, and you won't be learning anything.

Plus if you ever start not feeling out of your depth then you're either 9d or you're fooling yourself!
