I'm mid 1800s over on Lichess... Same here
I incorporated 1.d4 2. e3 & 3. Be3 into my repertoire. (Because I'm a Colle Koltanowski neophyte... they go to gether like peanut butter and jelly)
The Stonewall attack is Very underrated... There is a plethora of old school theory built off 1.d4 2. e3 & 3. Be3
GM Andrew Solits' Book The Stonewall Attack and..... I.A Horowitz & Fred Reinfeld's "How to Think Ahead in Chess" really got me into the Stonewall Attack.
Once you get used to working with the stonewall pawn formation, the static nature of it becomes a strength.
Hey there!
I have played thousands and thousands of games with the stonewall and I play it OTB (1760 FIDE rated currently) , so much so that I have practically mastered it and play it on instinct now. Its an incredibly underrated opening that goes against the normal chess rules by pushing the F pawn to secure the center in exchange for weakening your king. People in the 1900 and 2000s struggle to play against it. Try it out. Here is one of my recent games. The engine doesn't like when you play the stonewall since you are pushing the F pawn which is rarely a good move. But who cares about the engine when you play it against humans.
