Chess Game

With this game I got greedy and won material on the kingside by pushing all my pawns.  After that my king was a little exposed and I had a great deal of difficulty coordinating my pieces.  In the end, the extra material won.

I thought that Marti played way above her rating.  Marti meant to play c6 on the second move but touched her king knight and we went into the Marshal which I don't particularly like for Black.

Re: Chess quiz

This is an interesting chess quiz. If you wanted to cheat, you can
look at the source of the web page and not only see the correct moves
, but the scores it gives alternate moves.

4 friends at work showed this to me. Two of them got ratings in the
1200's and two of them got ratings in the 1500's. Between the 4 of
them they only got 1 puzzle correct. I took the quiz, only spent 25
minutes on it, got just 3 correct and a rating of 1890. The puzzles
are difficult.

Kayden

It looks to me like Kayden's results might be good enough to  get him over 2500 and finally make Grandmaster.  (I haven't tried to calculate a rating, but he did beat Ben Finegold.)  Going into the last round he is tied for second place.

For some reason the website is not allowing me to download all the games.  There is this win...
