grandmaster card ?

I read some news from politikencup the biggest tournament in Denmark

and the news stated that a GM was playing a game and got a worse position but then he threw the grandmaster card - which obviously mean that he offers draw.

and the other person acceptet.

is this some kind of courtesy that if you play a GM and get a better position that the GM can always getaway with draw?

is this some kind of term you have heard of grandmaster card?

that is strange- I have never heard of that- I think just offering a draw would be better

it was GM Richárd Rapport against someone with 2069.

I think he offered draw. but they wrote grandmaster card in the news but still sound like I am a grandmaster and you have to accept a draw. even though the position might be winning.

70 years ago saying was that if Reshevsky offered you a draw look if there's a mate in two on the board. This way he saved a draw on 1950 Olimpics in a game against Greek master (IIRC) Machtiadis.

P.S. I think that correct idiom is to draw a card, like in a card game. The way you wrote it, it look as he took his membership card in the GM association and threw it away - effectively resigning his membership.

Well, how much worse was the GM? It is not unheard of to take the surety of a draw instead of trying to capitalize on a minor advantage against a much better player. Against an equal player you would never offer a draw if you're clearly behind, so I think this is what they meant by playing the grandmaster card- he used the fact that he is much higher rated than his opponent - therefore has a good chance of overcoming his disadvantages - to offer, and get, a draw.

There is no such rule & I have never heard that expression before. There is a term "grandmaster draw", i.e. a short draw by mutual agreement.

found the game and I don't think the GM was so much worse

Grand Master card

The Hungarian grandmaster report was not good against Jens Jørgen Christiansen by city. "But then he pulled Grandmaster card," said Thomas Schou-Mold during analysis by commentator Per Andreasen in the auditorium. By Grandmaster card means that the Grand Master offers a draw when the post becomes wool, and the opponent receives respectful. Jens Jørgen Christiansen came immediately after up in the auditorium, and he said he was getting dark, so he accepted a draw offer, even though the position was quite favorable.

"Pulled the X card" is an idiom meaning you take advantage of the fact that you are "X."

"Pulling the grandmaster card," meant he took advantage of the fact that he is a grandmaster by offering a draw in a bad position, knowing his opponent might eagerly accept the chance to draw a grandmaster rather than risk losing later.

This thread made me chuckle 

I think you're right, but it probably doesn't always translate well.

please explain the picture I don't get it. I am not 100% sure who the stooges were or was.

The 3 Stooges were a Vaudville act in the early 20th century.  The point is "pulling a grandmaster card" doesn't mean a literal card, although it would be pretty cool if FIDE issued something like that.  It means the GM used his stature to his advantage.  The lower rated opponent was probably ecstatic for a draw against a GM and assumed that the draw was offered because the position was equal.

It is an idiom, but I think its roots are in the game of monopoly and the get out of jail free card.

I'm sure it predates Monopoly. If it comes from a game setting, I'd guess "play the trump card." Bridge-like games involving trump suits go back many centuries.

Assuming of course he does actually stand better, and not only thinks he does

why he thinks he's worse off”
