This is the final part of my series on the King’s Gambit. For many readers, who are not interested in this topic, it may have appeared to be far too long. However, the thing is, if you shout “Refutation!” you are obliged to deliver the proof. I hope, I have been successful with that endeavor and that some of you have enjoyed the ride!

4. Nc3 d5 5. exd5 Nxd5 6. Bb5+ {[#] This move has only been played 7 times in almost 800 games, but receives the highest evaluation by Stockfish. Here is, what may be the reason for this discrepancy: While it actually could be White's

best move, it doesn't appear to be very attractive due to its lame character.

White plays directly for the draw and doesn't receive any substantial winning

chances. Obviously, this perspective is rather unattractive for the average

King's Gambit player. Black has several options to play for a slight advantage

without any risk.} c6 7. Qe2+ Be6 8. Nxd5 Qxd5 9. Ba4 {[#] These moves are

more or less forced. Nevertheless, we already lost 6 of the 7 games we started
