Summary
You had a playable opening but lost the thread in the middlegame when time pressure kicked in. One hanging piece decided the game — fixable with a simple pre-move check habit.
What you did well
Main mistakes
Turning point
14…d5 — opened a line to your knight on c6. White's bishop took it next move and the position collapsed.
Main lesson: Before pushing a pawn, count attackers and defenders on the square you just opened.
Practice prescription: You missed 2 forks and 1 pin — start 10 fork drills, 5 pin drills, then one slow rapid.
