King's Gambit Allgaier Horny Defence

For a third time in a week I face the King's Gambit. Each time is against a slightly higher rated player. This time my opponent "lordbluff" (1877) played the King's Gambit. After 4.h4 g4 White usually plays the Kieseritzsky variation with 5.Ne5. In the game below White heated things up with the Allgaier variation with 5.Ng5?! In response to this knight Black does best to attack the knight with the h-pawn. Of 5...h6 George Walker wrote in "A New Treatise on Chess" (1833), "I consider this to be the best move for Black, although you certainly get a fine attack in exchange for the knight."

In turn White sacrifices the knight to open up the Black king by 6.Nxf7 Kxf7. In his 2011 book "The Petroff: an Expert Repertoire for Black", GM Konstantin Sakaev gives "7.Bc4 d5 8.Bxd5 Ke8 -/+ and his compensation for the piece is insufficient." I looked up the variation on Bill Wall's listing of opening names and found 7.Qxg4 Nf6! 8.Qxf4 was called the "Horny Defence" of the King's Gambit Accepted.

Who is "Horny"?, I wondered. I had owned a copy of George Walker's book so I began to search. Then I found a note on page 63 where Walker wrote after 8.Qxf4: "This move is given as best by Horny." He gave a footnote indicating it came from "Anweisung das Schachspiel" (1824) by Johann Horny, which does seem to be available in reprints today. Since Horny gave the line for White, I myself would have called it the Horny Gambit rather than Defence. In any case, I avoided the whole Horny line when I played 7...Qf6.

King's Gambit Accepted 3.Nf3 g5

In his classic book "Chess Advantage in Black and White", author Larry Kaufman writes: "The King's Gambit (1.e4 e5 2.f4) is among the most interesting and exciting of chess openings. Why then is it so rarely played in modern times? Very simply, both statistics and analysis show that the two sides have equal prospects, and serious tournament players are not satisfied with equality as White. Nevertheless, you will surely encounter it, and if you are not prepared you can expect to get into trouble."

For the second time this week I won a game with the King's Gambit 3.Nf3 g5 variation. This time we face a more critical line after 4.Bc4 Bg7 where my opponent "Voiarnalung" (rated 1820) challenged my f4-g5-h6 pawn chain with 8.g3. A wild 3-minute blitz game followed where both sides had chances. Eventually I managed to get a winning ending.

BDG Gambit in Opening Not Ending

Business shows clearly the connection between Risk and Reward. The entrepreneur with passion follows takes a promising risk to reap a precious reward. Jack DeBoer teaches kids from his experience how to manage risk in business. See Young Entrepreneurs of Kansas (YEKs). Chess brings out the risk taking Young Entrepreneur in players.

In the Blackmar-Diemer Gambit Ryder 5.Qxf3 e6 game Bill Wall vs "Yeks", both sides take risks. White sacrifices a pawn in the opening. Both sides have threats. By the 11th move, Bill Wall had regained his gambit pawn with equal chances. Then in the endgame Black sacrificed a pawn leading to a losing position and a feeling of resignation.

Wall with BDG: Ed Herm Plays 7...e6!?

In the Blackmar-Diemer Gambit Ryder 6.Be3 Qg4 7.Qf2, Black chooses a slower idea of 7...e6!? in Bill Wall vs Ed Herm (instead of the popular 7...e5!). In this line White has boldly gambitted away two pawns when both sides go wrong on move 8. The position is mostly equal until Black blunders on move 12.

Wall-Herm, Internet .25), 1998 begins 1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 exf3 5.Qxf3 Qxd4 6.Be3 Qg4 7.Qf2 e6 [This is a conservative version of the more assertive 7...e5!-/+] 8.Be2?

Bill Wall: Absent Without Protection

Yesterday I passed a guy at work with a tool bag that had the initials "AWP". I asked him what AWP stands for. He said, "American Work Products" available at Lowe's.

In the Blackmar-Diemer Gambit Ryder 5.Qxf3 Qxd4, Bill Wall varies from the normal 6.Be3 with 6.Bd3. He is immediately rewarded when "AWP" removes the Black bishop from its job guarding b7 to attack the White queen. The "AWP" queenside bishop could stand for "Absent Without Protection".

Wall-AWP, Internet .24), 1998 begins 1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 exf3 5.Qxf3 Qxd4 6.Bd3 [6.Be3] 6...Bg4? 7.Qxb7 1-0

King's Gambit Pawn In Endgame

The King's Gambit is a great opening with 200 years of famous games. White is given the chance to play very aggressively attacking the center and kingside. It often leads to a lot of fun. I have played the White side over 400 times and the Black side over 200 times.

After 1.e4 e5 2.f4, Black usually accepts the gambit with 2...exf4. The King's Gambit Declined 2...Bc5 is also good. In the King's Gambit Accepted, 3.Nf3 (which prevents the ...Qh4+) is five times more popular than 3.Bc4. Bobby Fischer and by many other masters used to prefer 3.Bc4, but it is not so popular in club practice.

I prefer the King's Gambit 3.Nf3 g5 line as Black. In my 3 minute blitz game "BBranko" (1712) I chose to set up a solid defence and hold on to the f4 pawn. Rather than hit my h6-g5-f4 pawn chain with either h4 or g3, White just left it intact. This allowed me to win with the extra pawn in the endgame. However, I missed pushing ...g4! on moves 7-9.

BDG: Extra Material vs Good Position

The defender in a gambit has the choice between keeping the extra material or improving the position. On the one hand, extra material can lead to a won ending as I demonstrate in a King's Gambit in my next posting. But, holding on to material allows the gambiteer an initiative that may force the defender to make serious concessions that may lead to a loss. On the other hand, there are times when returning the material for more piece activity or better pawn structure is preferred.

In the Blackmar-Diemer Gambit Teichmann, the bishop is not stuck to c4. As seen in the game Bill Wall vs Ghen, White answers 6...Nc6 with the pin 7.Bb5. Eventually Black is saddled with two sets of doubled pawns. The choice of trying to keep the extra pawn with 14...fxg6!? turned out to be in White's favor in the endgame.

Wall-Ghen, Internet .23), 1998 begins 1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 exf3 5.Nxf3 Bg4 6.Bc4 Nc6 7.Bb5 e6 8.0-0 Bd6 9.Bg5 0-0 10.Bxc6 bxc6 11.h3 Bh5 12.g4 Bg6 13.Nh4 Qd7 14.Nxg6 fxg6 [Black would do better to give back the pawn and keep his structure intact. 14...hxg6 15.Bxf6 gxf6 16.Ne4 Be7 17.Nxf6+ Bxf6 18.Rxf6 Rad8=/+] 15.Qe2 Nd5 16.Ne4 Be7 17.Rae1 Bxg5 18.Nxg5 Rxf1+ 19.Rxf1 Re8 20.Rf7 Re7 [20...Qd6=] 21.Rxe7 Qxe7 22.Qxe6+ Qxe6 23.Nxe6 [White has regained his pawn with a better endgame.] 23...Nb4 24.c3 Nxa2 25.Nxc7 Kf7 26.d5 [White is winning after 26.Na6!
