    • 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

    • 1973 Greater Philadelphia Invitational Championship (part 3 of 7)

      Michael Pastor was the young superstar of Philadelphia chess. Bright and chess-obsessed, Michael made master by his mid-teens, a feat quite less common than today. Not only that, but simultaneously I had been in one of my frequent "vacations" from... | Read More

      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

    • My Only Meeting with Al Horowitz

      The time was late 1968. I was 18, and I had just had a couple of strong tournaments that had gotten my rating close to the USCF's "Top 25 Juniors" list for the US. In those days the ratings were lower than they are now and there were fewer juniors... | Read More
