people who except a challenge ,make two moves then stop playing,expecting you to

You'd expect it to be accept, except it's not.  Accept it. 

Even native speakers are excepted from knowing the accepted usages in english and errors are to be expected

It doesn't happen in blitz a lot, mostly in longer games.

Well, before accusing somebody, what if the guy's wife just came in and he had to explain why in addition to playing chess he watches porn?

why play for a rating? I play to win.

Especially native speakers. No one is more ignorant of the English language than the vast majority of folks born and raised in England, the United States, Australia, ...

Hey now, aren't you missing someone?

How rude, yes it's true, Canadians are also quite ignorant of their native language

Wait that may not have come out right

Wow, here's insight into either my chess mistakes or the complete disregard of Canada.  Even with your leafy flag sitting there...I was thinking:  Um, no...he isn't missing anyone...who else...the Scots?  the Irish?    the Welsh?

The vast majority is ignorant in every language group That's why world shows so much discord.

I expect you to accept the fact that accept is spelt "accept" not "except".

But they only really do that if you are stupid enough to accept a 60 minute game.

I never play games of any longer than about 10-15 minutes.

Tbh, I mostly play 1-5 minute games...

 It only happens to me when I take a hanging queen or force checkmate in two with a brilliant sacrifice that My opponent won't move

You have ellipses in your post--even the correct number of dots (another rarity)--yet you fail to comprehend their meaning in my post. A list of three followed by ellipses extends the list to all others that fit within the specified criteria.

Poor Canada, they even held an Olympics not too long ago, and yet they're relegated to an ellipses -- don't worry Canada, I still love you

Surely the implied point is that Canadians are so awesome that they never misuse the english language?

Ziryab.  Just as I missed his flag, I missed your ellipses.  And missed Bxc3.  : (

With such spelling, I would think it would be near impossible to assemble a dissertation committee.

Trust me, that can't be it. 

Actually, "except" can be a preposition, as in your example, or a verb.  Did Bob get an invitation, or did we except him from the list?

It's indeed not nice, but if this happens to a person 2 times in a row, I probably won't accept a third game... But no, you said you put an open invite out there, yeah, if they hit on you three times in a row like that it starts to be annoying!
