hey OP, pretty sure i was touching 1800 blitz a couple weeks ago, and then i plummeted to 1400 blitz. and now im almost 1600 again.
its internet blitz, have some fun and try openings you dont play OTB and learn some new positions.
You are right and I do that all the time in internet blitz. I guess what irked me here , besides the fact that this person was faking a low rating, is the fact that it was a tournament. Other than that I totally agree with you, have some fun, loosen it up !!
I should repeat this bit, in case it got lost in the shuffle:
"The point is, if Black were a good player faking a low rating, no way would he play the terrible 27...Rxa7?? giving White an easy, easy win."
He was very good, so good infact that he knew he had to make a few poor moves, knowing full well that he could still win the game.
