Charles,

Your playing history is an anomally. I have played players 400 points below me
and lost and I have played players 400 points above me and won.

There are some players who play "similar" to computers in that for their level
of ability, they make very few tactical mistakes. You may be one of those types
of players. I am not one of those types of players. I can make a valid sac of a
knight against a player 600 points higher than me and worry the heck out of him
and 5 moves later, I can make a putzer move that 3 moves earlier, I mentally
said to myself could not be made in the game.

My current rating is almost 400 points lower than yours and I would make a wager
that in a 10 game match of 40/2 G/60, I would take 1 to 2 points from you. Why?
Because I sometimes play at expert level and sometimes play at D level. It just
depends on how well I am concentrating at the time.

Yermo will almost definitely not win 6-0. The reason is that if he is leading
the match (say 2-0), he will take a draw in a basically drawn position and not
push for a win that may not be there. This happens a lot at the GM level and I
cannot imagine that it will not happen in this match.

I have drawn or beaten at G30 or slower times every 1900-1999 player in the 2
main clubs I have played in within the last 3 years at one time or another and
my rating is currently in the high 1500s. I would predict that there are very
few players with your type of record.

Your assumption here is based on your previous assumption as to other players
having similar narrow banded win/draw/lose ratios like yourself. This is rarely
the case, so the second assumption here is probably also based on a false
premise. To illustrate my point, go to ANY state chess web page and look at the
results of recent tournaments. You will find many examples of players 150+ apart
where the lower rated player wins or draws against the higer rated player. For
example, just last year, a D rated player drew a master in our state. He even
had a won game, but he didn't see it over the board (he did see it on his own
after the game). This particular D rated player also played me during that
tournament. He had never beaten me in many G30 or slower games, but he beat me
that tournament. He was like a house on fire. It happens.

Well, I'm late. Gotta go. I'll add more later.
