Here is a game that highlights my lack of structural understanding! It was helpful to go through it with Nigel. Below is the game with Nigel’s notes. Nigel explained the big problem of my 10.dxe5 was that it gave Black the c5 square. 10. b5 would have been better.
He showed me two games of Korchnoi’s games (including one against Nigel!) with similar structural themes.
