Sawyer Gambit 7.g4!? in Benko vs Paul Norton

Paul Norton played the Benko Gambit vs me in 1981 at Allentown, Pennsylvania. Inspiration of the moment led me to a wild sacrifice that was a picture of my future gambit self. The Sawyer Gambit vs the Benko Gambit is the enterprising idea 7.g4!? that I invented on the spot. The idea is to gain time by quickly attacking the center and Black's kingside before he could attack my queenside.

The concept of deflecting Black's Nf6 away from e4 makes sense on some level. There is the Shirov-Shabalov Gambit in the Semi-Slav after 1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.Nc3 e6 5.e3 Nbd7 6.Qc2 Bd6 7.g4!? which is a hot topic nowadays. In our Benko, my 7.g4!? gambit worked in the sense that I took my opponent out of opening theory that he probably knew better than me. I got enough play to survive over the board in the final round while his clock was ticking. And yes, clocks actually did tick tock back then.

At some point in the year 1981 my rating was 1887. I use that rating for all my USCF games in 1981, though I was rapidly moving into the 1900s. All my opponents in this tournament were rated above me and I scored 2-3.

He has an extra pawn and seems to stand slightly better. However, White has a passed pawn and his knights are in a solid position. Black cannot easily make progress and our ratings were close enough so that a draw will hardly move them. We were both out of the running for any prizes.] 1/2-1/2

William Dempler Wins Nimzo-Indian Defence

William Dempler of Pittsburgh played the Nimzo-Indian Defence as my fourth round opponent in Allentown, Pennsylvania. Dempler was an expert and sometimes over rated 2200 as a master. The Nimzo-Indian after 1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.e3 allows for flexibility in how Black chooses to place his d-pawn and e-pawn.

The classical approach is to play ...d5 with a central pawn structure of e6, d5, c5, which I played as Black vs George Fawbush that same year. In our game below, Black chose the hypermodern approach by placing his pawns on the dark squares e5, d6, c5. Black exchanged his dark squared bishop on c3 before it became a bad bishop. He doubled my c-pawns and left me with a bad bishop on d3 that passively protected my blocked pawns on c4 and e4. Dempler worked up a kingside attack. Lesson: Attacking wins!

This event included Sergey Kudrin and Dmitri Gurevich, two grandmasters who had just arrived from Russia; they would face each other many times over 20 years. As I recall Kudrin was slightly higher rated but I think Gurevich won this tournament. The experience of watching more skilled players improved my play and raised my rating.

Sawyer (1887) - Dempler (2095), Allentown,PA (4), 14.06.1981 begins 1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.e3 0-0 5.Bd3 c5 6.Nf3 Nc6 7.0-0 Bxc3 8.bxc3 d6 9.e4 e5 10.d5 Ne7 11.Nh4 h6 12.f4 Bg4 [12...Ng6 13.Nxg6 fxg6 14.fxe5 dxe5] 13.Qe1 Ng6 14.Nxg6 fxg6 15.fxe5 dxe5 16.h3 Bd7 17.Qg3 Qe8 18.Bd2 g5 19.Kh2 [19.Rf2!?=] 19...Qe7 20.Qe3 b6 21.Be2 Qf7 22.Rf2 Qg6 23.Raf1 g4 24.h4?
