Its not really a dumb draw it is actually a very good one.
Black wants to control the e file with his rook but white keeps making the c7 threat.
If either diverts from there plan they will get a small disadvantage and in a GM game a small disadvantage is very major.
Seeing as white has over 100 less rating than black he was probably happy to draw, job well done.
White basically said, either give me a small advantage or I'm gonna draw the game which he did.
This looks like a case of white going for a draw honestly, which is sort of a "no no" in chess, but the guy he was up against had a much higher rating.
This is a game between two GM's, which ended in a quick draw. Thoughts?
