Hoping to get some feedback on a move. I am often caught in a situation where I can take/trade with more than one piece but no obvious (to me) why I should pick one option over another.
On move 20 of this game
I decided to take with the pawn because I thought that having 2 pawns in the center better against his lone pawn ...[text shortened]... w errors in the game but right now trying to focus on this specific decision.
Tough call. Your chosen move meant you had no isolated pawns, but created a weak backward e pawn. It also blocked the file for the rook, forcing it into passivity.
Taking with the Rook would have meant rooks on 2 open files, with the option of getting a rook battery on e file, but with a heavily pressurised d pawn.
I don't think that move was clear cut. But once you chose one over the other, you needed to play to the strengths/weaknesses of the position. In the game, doubling the rooks on the closed e file was very poor, as then both pieces were effectively taken out of the game.
You should work on your strategy: Silman's How to Reassess your chess is excellent. I hear Seirawan's Brilliant Chess series, including Strategy are good as well, especially for a novice.
