Strawman. Nobody is saying the 2700 will underestimate the 1300 and treat the game as frivolous.
if you are reffering to my comment, sorry. The history is past tense. They were highly rated players and were pounded into the ground like tent stakes. SWEET!
Rare? Granted. But to the topic's heading, entirely possible.
I guess maybe the higher rated players may have used your words as their excuse...but then, they wouldn't have been that highly rated, eh?
Yes, but 2700s tend to see checkmate very very well...
And a 1300 isn't at all likely to get into a position where he or she has checkmate against a 2700...
