    • 1973 Greater Philadelphia Invitational Championship (part 7 of 7)

      The seventh and final round was the only game on Sunday, so I had an entire day to prepare. I had a half point lead; a draw would clinch a tie for the title and a win, of course, made me the outright champion on my first attempt. My opponent was ... | Read More

    • 1973 Greater Philadelphia Invitational Championship (part 6 of 7)

      With the possible exception of Round 1 and a little bit of Round 2, all of the previous games were fairly unbalanced and all, without exception, were decisive. This changed in Round 6 when I got a nice opening advantage against Joe Weber, and cou... | Read More

    • 1973 Greater Philadelphia Invitational Championship (part 5 of 7)

      The first four games of this round-robin event were played on the previous weekend, and July 14-15, 1973 were the dates for the final three. My first opponent on the second weekend was Harvey Bradlow, an old friend/nemesis from our junior days (a... | Read More

    • 1973 Gr Phila Invitational Championship (Part 4 of 7)

      Compared to some of the other veterans at the Germantown Chess Club, Lou Golder had not been one of my frequent opponents. Possibly I had played a loss against him when I was weaker and a draw after I got stronger. In any case, I really did not kn... | Read More

      [This is the second in a series of 7 blogs about the 1973 Greater Philadephia Invitational Championship - link for Part 1] When I first started playing tournament chess in the late 1960's and early 1970's, "Master" was a very difficult title to a... | Read More

    • 1973 Gr Phila Invitational Championship (Part 1 of 7)

      This year marks the 40th anniversary of the 1973 Greater Philadelphia Invitational Chess Championship. In honor of this event I thought I would write a 7-part series with light annotation of my game in each round. Each blog will primarily consist ... | Read More

    • Middlegame Book Suggestions

      I often get asked various questions about how to play the middlegame, and I think playing many long-time control games slowly against good opposition and then carefully reviewing those games afterwards is the best way to learn about pretty much an... | Read More

    • The DATSCAN

           There are lots of things an instructor can do during a lesson to help a student, such as reviewing games, answering questions, or having the student do "indicative" puzzles. But I also include three types of exercises which I periodically ... | Read More

    • Move every piece once...

      The grandaddy of all opening principles is "Move every piece once before you move every piece twice unless there is a tactic." In his venerable book Common Sense in Chess, World Champion Emanuel Lasker's rules for development of the pieces #2 is "... | Read More
