Louis Paulsen lost this game — and the engine says it slipped away on move 20 (Rd1). They think you'd have lost it too. Take the board at that exact moment and prove them wrong.
At move 20, White played Rd1, dropping the position from merely difficult (-3.44) into completely lost territory (-15.00). The rook move failed to address Black's overwhelming attack and left White's king fatally exposed. Paulsen needed the defensive 20.Qd3 instead, which would have kept the game theoretically playable.
