L'Ami struggles against 2100 Elo player - The Underdog

by Arne Kaehler
8/11/2025 – 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.

The Underdog!

We all love stories where a vastly underrated player surprises everyone by beating a much stronger player. Fortunately, we are all human.

But how do these things happen? What are the moves that lead to success? And what can we learn from these examples for the times when we face a stronger opponent?

Dutch IM Robert Ris presents us with real-life examples of such encounters from the past month. Together with his co-host Arne Kaehler, they look at the tactics and strategies that led to the upset.
