Schmoldt vs Muhr Lemberger 4.dxe5

The Blackmar-Diemer Gambit was avoided with a BDG Lemberger 3...e5 in a game played last month between Ruediger Schmoldt of Germany and Andreas Muhr of Austria that began as a Scandinavian Defence 1.e4 d5 2.d4. White chose the same 4.dxe5 drawish line that I had tried vs Tim Harding. In that game I continued 5.Nxd1 and was outplayed by my Irish opponent. In the game below Schmoldt chose 5.Kxd1.

Being unable to castle is not such a problem when the queens are off the board and no pieces are developed. The main thing is to coordinate your own pieces and to make sure all the key squares are protected. With that taken care of, you have to look for ways to unbalance the position in hopes of victory. Schmoldt tries the risky 11.e6!? and Muhr manages to obtain a small advantage.

Schmoldt (2147) - Muhr (1962), 30th Faaker See Open 2014 Latschach AUT (6.11), 13.08.2014 begins 1.e4 d5 2.d4 dxe4 3.Nc3 e5 4.dxe5 Qxd1+ 5.Kxd1 [Another popular continuation is 5.Nxd1 Nc6 6.Bf4 (6.Nc3!?

Stephen O'Shea Hot Queens Gambit

We were hot. Burning hot in Hatboro. The air conditioning was not working this day at the tournament site. I was sweating like a pig while trying to play serious chess. How do you handle poor playing conditions? As a young man in 1981, I handled it very foolishly. The temperature reached 95 degrees Fahrenheit on this Sunday in Philadelphia. The front doors to the building were left wide open so that at least we would get some moving air from outside as we crowded around the chess tables inside. The air was still.

Our opening an Orthodox Queens Gambit Declined which leads to longer games. My opponent for the fourth round was Stephen O'Shea. He had to be as uncomfortable as I and everyone else in the room was. I lived in the South 1977-1980, but by the summer of 1981, my body reacclimated itself to Northern weather. Our bodies naturally thicken our blood in cold climates to conserve heat and thin our blood to release heat in hot climates. Now in Florida my body is used to 95 degree temperatures, but not in 1981 Philly.

So what did I do? I decided to play my tournament game as if it was blitz chess. My opponent was rated 300 points below me. All things being equal the odds of me winning were excellent. But my choice to play without much thought was stupid. O'Shea wisely played at a normal pace. For the first dozen moves we played a well-known solid book line. Three months earlier I had won a club game vs John Mack with the move 13.Qb1, a favorite of Najdorf. In later years I preferred 13.dxe5 Nxe5 14.Nxe5 Qxe5 15.f4 and tried to outplay my opponents from an equal but unbalanced position.

In the game below I am winning through move 27. Then I throw it all away in the heat of the moment with blunders on moves 28 and 29. Now fired up I stubbornly suffer on until move 65. Stephen O'Shea holds his advantage and earns a well deserved victory. USCF lists shows one Stephen O'Shea who obtained a rating in the 1700s and plays in tournaments down South in the Huntsville, Alabama. I wish him well.

Sawyer (1887) - O'Shea (1583), Hatboro,PA (4), 19.07.1981 begins 1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Bg5 Be7 5.e3 0-0 6.Nf3 Nbd7 7.Rc1 c6 8.Bd3 dxc4 9.Bxc4 Nd5 10.Bxe7 Qxe7 11.0-0 Nxc3 12.Rxc3 e5 13.Qb1 [This is a rare line meant to support b4 and cover the b1-h7 diagonal.

Sawyer Gambit 7.g4!? in Benko

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.

Loss vs David Kistler in Benoni Defence
Draw vs David Kushner in Gruenfeld Defence
Win vs Bruce Davis in Caro-Kann Defence
Loss vs William Dempler in Nimzo-Indian Defence
Draw vs Paul Norton in Benko Gambit (below)

Sawyer (1887) - Norton (1915), Allentown,PA (5), 14.06.1981 begins 1.d4 Nf6 2.c4 c5 3.d5 b5 4.cxb5 a6 5.bxa6 Bxa6 6.Nc3 d6 7.g4!? [7.e4 Bxf1 8.Kxf1+/=] 7...Nxg4 8.e4 Ne5 [8...Bxf1 9.Kxf1 Nf6=/+] 9.f4 Bxf1 [Or 9...Ned7=] 10.Kxf1 Ned7 11.Nf3 g6 12.h4 Bg7 13.h5 Qa5 14.hxg6 hxg6 15.Rxh8+ Bxh8 16.Bd2 Qa6+ 17.Qe2 Qxe2+ 18.Kxe2 Na6 19.a3 c4 20.Be3 Rb8 21.Bd4 Bxd4 22.Nxd4 Rxb2+ 23.Ke3 Rg2 24.Nde2 g5 25.Kf3 Rh2 26.fxg5 Ne5+ 27.Ke3 Nc5 28.a4 Ned3 29.Kf3 Ne5+ 30.Kg3 Rh5 31.a5 Rxg5+ [Probably Black offered a draw here. 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
