Some members don't accept a rematch request because there are so many sore losers on this site. Instead of disconnecting during the first game, the defeated opponent might instead seek "revenge" in the rematch game by sicking their chess engine on you (pathetic, isn't it?). I never play rematch games in OTB tournaments, so I feel no obligation to do so online. But if the opponent seems friendly or at least cordial, I might still accept the request anyway, against my better judgement. Sorry if I sound cynical, but I have seen and heard of much juvenile behavior here.
Would it hurt to rematch?
I always take a break after the game is over - because I need to analyse it and to take a break and relax. So for me - yes, it would hurt to rematch.

I think rematching is good if you have the time. If you don't have the time then don't! -Kingdom_Hearts

do you mean accepting another game after playing one in live chess? sometimes people want a break to analyze the game, sometimes you have to go to the bathroom, sometimes you've already played three games or six games and need a break, what does it have to do with character?

Bean ... what do you mean "demand"? I just press the rematch button. What are you even talking about? No point being clever for clever's sake.
Actually I don't play a lot of blitzes recently. i play online.
You said : " But I notice that most people here don't. I don't have a very high opinion of such people - and sadly enough there are more than enough of such people here."
Why do you look down on ppl who don't rematch? It's not an obligation. You already know that most of the players won't.
You said "It's not a big deal, of course I get over it." So why do you start a thread like this?
I think you just try to get your anger out.

No it wouldnt hurt. I usually rematch unless the other guy play to the end a totally lost position (2 pieces down for example... why they do that? better if they resign and ask for a rematch) or I had to go because Im tired of playing
For me it's more fun to play another game with another opponent, not with same one. What's wrong with this?

I rematch unless either A. I complete crush the guy so hard there is no challange. Or B. Im the guy getting crushed. If me and somebody that is about equal and we play a very good game. I always request or accept rematchs.

if you think someone not accepting a rematch makes them less than you then you are a punk. there are 1 million reasons someone wont accept a rematch and 999,999 of those reasons have nothing to do with you. the narcissism of this post hurts my eyes to read.

At slow time controls, I prefer to annotate my games immediately while they're still fresh in my memory, so yes, it would hurt to rematch.
Why do you think you're entitled to multiple games from a person? Maybe you were too weak and they want more of a challenge, or maybe they just don't feel like playing you again. There's nothing wrong with that.

Yes, it would. It hurts a lot. Because you demand it instead of requesting.
i agree . i rematch if i feel like it , i dont if i dont , period.
Axe20131010, do you ever take time to read what others have to say?
After a game is over I want to 1) analyse; 2) relax; 3) find another opponent. I play chess for my own fun, not for yours. Got it?

If they're someone i'm kind of familiar with, or friends even, i'll accept or offer an rematch (if i have the time) in Live games. Online games i tend to accept rematches, but hardly ever offer one (almost never, unless they're friends and we agreed to an 'match' kinda deal). Otherwise, i don't think it's in bad taste or an character flaw to decline. Likewise, if i offered an rematch but the other party declined, i wouldn't think nothing of it. I'm sure we'd probably meet up again sometime anyways.
Your personal habits are not representative, genius.
I was not trying to be representative, just telling you why it would hurt me to rematch.
And by the way what I said is representative - others bring more or less same reasons plus the obvious ones like too tired, too late, already too much chess, other responsibilities etc.
Now explain me what's your problem?
Someone once said, "character is who you are in the dark". I used to rematch, not thinking much about losing after winning. But I notice that most people here don't. I don't have a very high opinion of such people - and sadly enough there are more than enough of such people here.
It's not a big deal, of course I get over it. But, personally I don't think sportsmanship is aplenty in quite a lot of folks here.
