I keep returning to the combination of artistry, complexity and romanticism that is the Evergreen Game. The freshness of ideas that occur with close analysis continues to intrigue and inspire each new generation of chess players who choose to explore this breathtaking game. In fact, the actual moves of Adolf Anderssen and Jean Dufresne are just the beginning, the true beauty of The Evergreen Game lies in the endless possibilities surrounding blacks infamous 19th move. Had Jean Dufresne chosen better there, I remain confident that the game would still be evergreen. In my notes below I include all of my discoveries from two decades of teaching the game. For ease of study, I recommend copying the text and pasting it into your favorite chess program. Enjoy!

The Evans Gambit is an aggressive choice named after the Welsh sea Captain
William Davies Evans. Here white gladly offers a pawn so he/she can open the
center and develop faster than in the Giuoco Piano(1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5
4.c3 Nf6 5.d4) by not having to spend a tempo on playing pawn to c3.}
