The King’s Gambit is one of the oldest openings and was already mentioned in 1497 in Lucena’s Repeticion de Amores y Artes de Ajedrez. It has amused us with countless fantastic attacking games and was successfully adopted by world champions such as Spassky and Fischer. Despite its doubtful appearance, it has posed great practical problems for generations of black players.

This glorious history cannot be taken from the King’s Gambit. But these are tempi passati. Nowadays, we have strong engines that ring the alarm bell when something is not quite kosher. With their help, you can even analyze certain position types until you reach a final verdict. This means the end of an era and the inevitable decline of all incorrect gambits.

In my opinion, the King’s Gambit is clearly refuted by the Schallop Variation. Even though my analysis presents numerous innovations, the fundamental strength of this line has already been demonstrated quite well by older game material. I am hence surprised that repertoire books on the King’s Gambit are still being published, black players lose helplessly and that even grandmasters have no qualms about making it their choice. Well, apparently the market for chess ideas is simply not efficient enough, even in times of the Internet. This provides my followers with the chance to profit from the following information. Good luck!

can look out for opportunities to return the pawn in order to transform his
material advantage into a positional one.} 3. Nf3 (3. Bc4 {is not worse, but

Schallop Variation is based on solid principles. Black develops and at the
same time puts pressure on White's center.} 4. e5 {With this move, White at
least maintains the illusion of an initiative. However, it is well known that
advanced central pawns often lose their power, as they abandon important
squares (d5 and f5) and can be attacked by hostile forces (d7-d6). The
alternative 4.Nc3 is not worse and will be covered later. The psychological
problem with this move is, however, that it already looks like an early
admission of failure.} (4. d3 $2 d5 5. e5 Nh5 $17) (4. Bc4 $2 Nxe4 $1 5. Qe2 (

analyzed in concrete fashion. And yet, the quality of Black's play can
already by estimated on an abstract level. First of all, Black's extra pawn
is now solidly defended. This is annoying for White, as it frustrates White's
ambitions in the f-file. Normally, White removes this obstacle by using the
pawn break g2-g3. But now, this mechanism gets potentially disturbed by the
daring Schallop-knight. The material now branches into three sub-variations: a)
5.Be2, b) 5.Qe2 and c) 5.d4.} 5. Be2$6 {White prepares castling and at the same
time targets Black's knight. The bishop has to make do with this relative
modest location, as} (5. Bc4 $2 d5 {(remember when I commented that 4.e5

} 6... Ng7 {This is not only a prophylactic measure with the aim to remove the
knight out of the danger zone. The knight is excellently placed on g7, as it
controls three important squares. Moreover, it will now be able to occupy a
fantastic position on either e6 or f5, depending on the concrete proceedings} (

example for my remark after 2..exf4. Incorrect gambits such as the King's
Gambit are best refuted by giving up the extra material in return for
positional assets in a suitable moment. That way, the former attacker is
deprived of his dynamic potential and has to look down on a dreary position.
In this situation, the hunter clearly turned into the hunted, as already five
black pieces are directed towards the white king.} 11. Bc4 (11. fxg5 $2 hxg5

meager result for a white opening.} *
