The US Championship is being broadcast at www.uschesschamps.com and both the Capablanca Memorial and the US Championships are being broadcast at  www.2700chess.com    Rounds start at 2 pm in Saint Louis and 3 pm in Cuba.   2700chess has larger boards than the official site but doesn’t show the time remaining and appears to start with a 15 minute delay.
 
   The computer does not think this week’s game was particularly well played, but it seemed exciting at the time.  With neither king able to castle, my attack arrived first when my opponent grew short of time.
  This week is my first use of the newest HIARCS software to analyze the games.  Unfortunately the program now scores all the evaluations from the White point of view.  The previous software evaluated the position for whomever was on the move, which makes a lot more sense and is easier to read.  For example, the MINUS point seventy-two after Black’s 9…Nf5 means Black is actually winning by that amount.  Eventually, half of my accumulated game files are going to read one way while all the newest entries read another.  I haven’t found anything in the software’s preferences to correct this confusion so we are all just going to have to get used to it.  The pgn file it prints out also looks a little weird.  It’s just a reminder that when it comes to purchasing computer chess software, user-friendliness counts for more than whether the program sees fourteen moves ahead or sixteen moves ahead.
