In the 2025 Vlissingen Open, 2117-rated Joel Van der Werf, playing Black, faced Dutch GM Erwin l’Ami, nearly 500 rating points higher, and impressively outplayed him for much of the game. Using precise, prophylactic pawn moves and harmonious piece coordination, Van der Werf steadily restricted White’s activity, expanded on the kingside, and reached a clearly superior position. However, in a critical moment on move 40, he traded his strong bishop for a knight, and the game eventually ended in a draw, a fine underdog result but one that could have been an upset win.
