--> I tried to seek for an answer myself, but couldn't find it..

A nice guy I often play with has the habbit to check my king move after move with the same piece (I give him this opportunity because I dont want to putt my king on an other spot).

This is apparently a matter of etiquette:

- Should he abort checking me this way and come up with a new plan,

- or should I give up and putt my king on a spot where I dont want it? 

I think he should stop, although I'm not sure.

Thanks in advance! 

offer a draw

One could say end game has started. I have more points. I dont want to offer a draw... 

He may continue to do this as long as he likes. If you move your kings to the same 2 squares over and over, the game will likely be a draw. If you don't want a draw, you should put your king on a new square where he can avoid check. He may do this as long as he likes, it is your choice whether to declare the game a draw by repition, or move to a new square.

If you want more than a draw you have play some other move, obviously.

True, but the thing is, his attack is not quit constructive. He is only attacking by queen and could never mate me only with that. 

Repeating the same moves is not very elegant - (and therefore I suppose some form of etiquette), but since he is the aggressor, I have little choice. 

Forgive me my nagging, it does not sounds satisfying yet. The two options I have, making another move or offer a draw.. Is this common sense or are these ''chess rules'' ?  

And here is the answer!

I was unaware that you didn't know it.

The player who wants a draw should offer it. If the other player declines he should try to win (else declining the draw wouldn't be very sensible).

But, as in your case, if you want to win and your opponent just keeps repeating moves without a draw offer, what could you do? I see only two options: offer a draw yourself or keep on playing until one of you falls off of the chair in exhaustion. I'd prefer the former.

Offering a draw yourself also puts the pressure on your opponent: if he declines he'll has to show something to justify his decision. Sometimes he will overdo and lose. This little trick won me quite a few drawn endgames.

You have to stop leaving yourself open to purpetual checks. It is not so much an etiquette issue as it is weak play! You don't want to let yourself be continuously checked in a winning position because that is the best option for your opponent to get a draw instead of a loss. You want to play some games tomorrow Misha?

People who just keep checking are soooooo annoying

Well, we give people all sorts of flak for starting new topics on subjects that have been covered already, so we can't complain too much at the resurrections.

Endless checking is a legal way to force a draw or blunder. There is nothing wrong with this play. If you have less time, offer a draw or claim a draw by threefold repetition. If your opponent have less time, try winning on time.

Yeah, weird, that....

If they are all cowboy checks he is perfectly within norms....tell him-"make moves that suite me".A little silly. Tuck the king into a non-check situation and guess what ? The checking stops.

Hahaha

It seems to me as if OP can't accept, that more material doesn't always result in a victory. If the opponent has a way to force a draw (perpetual check, stalemate or whatever), it's a draw. Chess is not a race in gobbling up material.

Indeed, I think sometimes the points values mislead people, especially when displayed as absolute values in online chess.

I had a situation recently in online chess where my opponent and I had moved the same pieces several times into the same positions. I offered a draw, but he declined.

Then I noticed that a new button had appeared on the screen: "Claim draw." Apparently chess.com's computers recognized that we had gotten to a threefold repetition, so all I had to do was click the button, and the game was over. If you want to win, you'd better be careful not to get into a threefold repetition, or that button will appear, and then all your opponent has to do is click.

That's why you're never repeating three times if you're not satisfed with the draw.

I thought this was about checking our variations and analysis after every move and how mentally straining and tedious it can be.  As much as I liked Kotov's Think Like a Grandmaster checking variations once and once only is bad advice, especially for someone like me who returns to previously analysed variations and notices things I didn't the first time around.

  Also, it's continuously.
