Fries Nielsen Big Pawn Advances

Fries Nielsen enjoys a variation which begins 1.d4 d5 2.Nc3 Nf6 3.Bf4. What originally caught my eye was the BDG style pawn advances with 4.f3, 5.g4, 6.h4, along with an un-BDG like move 7.e3. This Fries Nielsen opening is not quite a Veresov that begins 2.Nc3 Nf6 3.Bg5, nor is it quite a London System which begins 2.Nf3 Nf6 3.Bf4.

The International Master Jens Ove Fries Nielsen of Denmark faced Patik Drugge of Sweden in another game in this line. Here Black played 6...h6! which appears better than 6...h5 which I covered in my earlier Fries Nielsen post. After 7.e3, popular chess engines offer several alternatives to 7...c5 in 7...a6 Stockfish, 7...Bd6 Houdini and 7...Be7 Komodo. All these lines leads to equal chances, but of course that also means the better player has the better chances.

Fries Nielsen (2442) - Drugge (2175), Visma IMB 2015 Vaxjo SWE (8.2), 28.06.2015 begins 1.d4 d5 2.Nc3 Nf6 3.Bf4 Bf5 4.f3 e6 5.g4 Bg6 6.h4 h6 7.e3 c5 [7...a6 8.h5 (8.Bd3 Bxd3 9.Qxd3 c5 10.Nge2=) 8...Bh7 9.Bd3 c5 10.Bxh7 Nxh7 11.Qd2=] 8.Nb5 Na6 9.c3 [9.a3=] 9...Be7 10.Bd3 Bxd3 11.Qxd3 Qb6 12.a4 Nd7 13.Ne2 c4 14.Qc2 e5 15.Bg3 0-0-0 16.b3 Nc7 17.bxc4 dxc4 18.Rb1 Na8 [18...h5 19.g5+/=] 19.Qa2 a6 20.Na3 Qc6 21.Nxc4 Qxf3 [21...f6 22.Na5+-] 22.Rf1 Qd5 23.Qb3 b5 24.axb5 axb5 25.Qxb5 Qxb5 26.Rxb5 Nc7 27.Ra5 exd4 28.exd4 Nf6 29.Bxc7 1-0

Sicilian Defence Bg2 Without Nc3

Kingside fianchetto chess moves in the Sicilian Defence are common for Black with Bg7 Dragon variations. The White move Bg2 appears in the Closed Sicilian after 2.Nc3. Why? Because an e4 pawn, Nc3 and Bg2 fight against Black's d5 square. When White controls d5 in the Sicilian, he slows Black's counter attack. What if White plays Bg2 without Nc3? Black reacts quickly with ...d5 and instant equality.

Ernest Huber competed actively in APCT postal chess in the late 1970s and early 1980s. We met in four times when I was always slightly higher rated. Here White's creative set-up fell apart due to the 10th move. White turned his attention to the queenside where Black had castled. Alas the main action was on the kingside where White had castled.

Huber (1850) - Sawyer (2050), corr APCT 1980 begins 1.e4 c5 2.Ne2 Nc6 3.g3 d5 4.Bg2 dxe4 [4...d4 5.d3 e5 6.f4=] 5.Bxe4 Nf6 6.Bg2 [6.Bxc6+ bxc6 7.d3 g6=/+] 6...Bg4 [6...e5 7.0-0=] 7.0-0 Qd7 8.d3 0-0-0 [8...e5 9.Nd2=] 9.Nbc3 h5 10.b3?

Blackmar-Diemer Algeria Masters

When you reach the Blackmar-Diemer Gambit after 1.d4 d5 2.e4 dxe4 3.Nc3 Nf6, how should you play if your opponent declines your 4.f3 pawn offer with 4...e6? The first thing is for you to regain the pawn with 5.fxe4. In this French Defence type position, Black continues 5...Bb4. Material is even.

White must deal with Black's immediate threat against the White pawn on e4, as well as potential threats against d4 and the pinned knight on c3. Sharp tactical play is required by both sides to avoid losing quickly. White's choices are 6.e5, 6.Bd3, 6.Qd3 or 6.a3. He cannot play them all, and certainly not all at once.

Two master level opponents from Algeria with almost identical ratings transposed to the Blackmar-Diemer Gambit. This BDG Weinspach Variation 4.f3 e6 was played by Moussa Sidali (also called Sid Ali) and FIDE titled master Khalil Bengherabi. Chances were equal for the first 10 moves, but then Black gradually got the upper hand. Ironically Black's last move was 28...f3 when White resigned.

Sidali (2202) - Bengherabi (2201), 13th Ameyar Mem 2015 Algiers ALG (6.9), 12.06.2015 begins 1.d4 Nf6 2.Nc3 d5 3.e4 dxe4 4.f3 e6 5.fxe4 Bb4 6.e5 Nd5 7.Qd3 c5 8.a3 cxd4 [Other options include 8...Qa5 9.Bd2 cxd4 10.Nb5 Bxd2+ 11.Qxd2 Qxd2+ 12.Kxd2= and 8...Ba5 9.b4 cxb4 10.Nxd5 exd5 11.axb4 Bxb4+ 12.c3=] 9.axb4 dxc3 10.bxc3 Qc7 11.Bd2 [The simple 11.Nf3 gives White a good game. 11...Nd7 (11...Nc6 12.Qc4 0-0 13.Be2 Qb8 14.Bf4=) 12.Qd4 Qxc3+ 13.Qxc3 Nxc3 14.Bd3 Nd5 15.Bd2=] 11...Qxe5+ 12.Be2 Nxb4 13.Qc4 N8c6 14.Nf3?

White chooses to attack kingside and hope. The alternative 19.Qd3 Qc1+ 20.Bd1 0-0-+ gives Black as solid position.] 19...0-0 20.Ng5 h6 21.Nf3 e5 22.Qh5 Be6 23.g4 e4 24.Ne1 f5 25.g5 f4 26.gxh6 Bh3+ 27.Ng2 Bxg2+ 28.Ke1 f3 0-1

Goring Gambit Endgame vs Moore

The Scotch Game has important side variations after 2.Nf3 Nc6 3.d4 cxd4. In my 4.c3!? Goring Gambit postal chess contest vs Robert Moore from APCT in 1978, Black chose to accept the gambit pawn with 4...dxc3. White built up a standard attack on the squares e6 and b7 which I defended with 10...Qc8!? After a long battle where both sides had chances, we reached an even rook and pawn ending.

I remember writing out pages of analysis following principles I learned for endgame texts. One of my favorites was Fine's Basic Chess Endings which was later revised by Pal Benko. I read the original descriptive notation version cover to cover in the mid-1970s. I thought I had everything worked out for a draw, but I miscalculated and threw the game away. I think my opponent was Robert C. Moore from North Carolina which USCF lists these many years later as having a 1887 correspondence rating.

George Fawbush Finds Dutch Win

When you play the same opening pawn structure repeatedly, you become comfortable, and maybe competent. Or you can slip into lazy lackadaisical lost positions. The Dutch Defence can be played by Black against anything except 1.e4. My set-up here was the Classical Ilyin-Zhenevsky 3...e6 and 6...d6 variation of the Dutch favored by GM Simon Williams. Black leaves the center available for moves like 5.c4 and 6.d4.

I played George Fawbush nine times in my postal chess career. In six I had the Black pieces. We both scored +4 -4 =1. "G.E.F." played a wide variety of openings, often at a 2300 master level. At times, he dropped out of tournaments for health reasons.

Basically my Dutch becomes a Bird's Opening in reverse. It feels like I just passively sat back and waited for things to happen. The real danger comes when White gains the initiative and wins material. Here I resigned when down two pawns.

Fawbush (2200) - Sawyer (2100), corr APCT 1982 begins 1.g3 f5 2.Nf3 Nf6 3.Bg2 e6 4.0-0 Be7 5.c4 0-0 6.d4 d6 7.Nc3 Qe8 [A critical line is 7...Ne4 8.Qd3+/=] 8.Re1 Ne4 9.Nxe4 fxe4 10.Ng5 d5 11.cxd5 exd5 12.Qb3 c6 13.f3 Kh8 [13...a5 14.fxe4 a4 15.Qc3+/=] 14.fxe4 h6 15.Nf3 dxe4 16.Nd2 Bf6 17.e3 Qe7 18.Nxe4 Be6 19.Qc3 Nd7 20.Nxf6 Nxf6 21.e4 Rad8 22.Be3 Bg4 23.d5 Rfe8?

Backing Into Four Knights Game

The Queen's Knight Attack first move 1.Nc3 found its way into almost every game I played during 2003. From there I took whatever path I felt like at the moment. That might mean a visit to an original line or maybe a transposition into a popular opening variation. Here we passed from a Vienna Game to a Spanish Four Knights Game after 4.Bb5 Bb4, I benefited from Black's move 7...a6 which proved to be too slow. Later I mounted a strong attack and checkmated her on move 19.

By opponent's handle was "lynch_valeria", which happens to be the artist stage name for an Argentine singer and actress who is about my age. Whoever she is, a 1701 Yahoo rating was pretty good since they started everyone at 1200. Yahoo chess ratings over 2000 were rare when I played there, except for maybe computers rated 3000.

Sawyer (1900) - lynch_valeria (1701), Yahoo 2 12, 13.08.2003 begins 1.Nc3 Nf6 2.e4 e5 3.Nf3 Nc6 4.Bb5 Bb4 5.0-0 Bxc3 6.bxc3 0-0 7.Re1 a6? 8.Bxc6 dxc6 9.Nxe5 Re8 10.d4 c5 11.Bg5 [11.Bf4!?+/-] 11...cxd4 12.cxd4 h6 13.Bxf6 Qxf6 14.Qf3 Qb6?

Caro-Kann Defence Dennis Kiick

The Caro-Kann Defence leads to solid play. White can open up the position by 3.exd5 with a Panov Attack 4.c4 where tactical skill is rewarded. Chess is fun as a hobby. Some find glory while others achieve more notable accomplishments beyond chess.

White below is Dennis Kiick whom USCF lists as living in Tennessee. I assume he is Dr. Dennis Kiick, learned professor at Lincoln Memorial University who is an expert in health and history. We played two APCT postal games simultaneously. As White I won a Queen's Gambit Declined, but in both games he played logical moves throughout.
