How do you call such players ?

@drumteatr
I think you don't understand my point.
Suppose your opponent is the king of fairplay. When is it OK, according to you, to leave the match ?
- When the munber of played games is even ?
- When the score is even (It might never happen) ?
- When one or the other wins two consecutive games (It might never happen) ?
- When you have played let's say 27 games, forgot the "history", and start to be tired, what should you do ?

What are the "unspoken things/rules" ???

@Brno7, i think you should read title post again.

There is number of players up to 10-15% who play with you only until they win.That is it. This is just fact.
With my statement wanted see if someone else noticed this pattern as well or not.
According to answers, looks like reason is sudden eat/analysis/sleep/fatigue itch. ;)

Probably this could be only Blitz/Bullet pattern, need check classic games.

@drumteatr

I think you are on to something and you should spend a lot more time trying to get to the bottom of this sinister situation. Ultimately obsessing over this for as long as possible will do more to improve your game than trivial pursuits like analysis of your play, or taking an early morning walk.

You have stumbled into the entrance hall of chess mastery and I will no longer go along with this concerted effort to block you out of the secret chamber. This is it man. People who decline a rematch. Never forget. :)

I never noticed such a behaviour like @drumteatr seems to notice. ANd I do not think there is such a thing as rematch obligation. You never can expect of anybody to have another 20 or 30 minutes of spare time for playing chess.

But @Brno7 asked a very polite and patient question. What would be the real fair play criteria for leaving? After the second defeat? Is that your answer, drumteatr? Or after the second defeat in a row?

I think it's quite normal though...

Psychology. Some people get enraged by losing - so if you are that kind of person and the opponent beats you and asks for a rematch and he KNOWS that you are angry - you might as well decline and move on.

Because playing while raging ( do they call that "tilted" around here ? ) might lead you to select sub-optimal moves.

The logic part of your brain finds better chess moves than the animal rage part of your brain (:-)

When my opponent won he went.

Among other probable causes, like
- sinister plots to expropriate you of a handful of worthless ratings points,
- being shaken to his core because of the vast amount of skills you just exhibited,
- the porn movie he was watching in another browser window was starting to get interesting,

he maybe simply have deemed you not strong enough to make playing you interesting and worth his while.

But I won some game against him before.
