Magnus Carlsen suffers rare classical defeat to Jorden van Foreest

World No.1 Magnus Carlsen suffered a rare classical chess defeat, losing to Dutch Grandmaster Jorden van Foreest in Round 4 of the TePe Sigeman & Co tournament.

The loss ended Carlsen’s unbeaten classical streak of nearly a year, his first since falling to D Gukesh at Norway Chess. The game featured a tense middlegame and a complex endgame, where Carlsen looked set to hold for a draw before late mistakes proved costly.

Van Foreest admitted he expected a draw before capitalising on Carlsen’s time trouble. Elsewhere, teenage prodigy Yagiz Kaan Erdogmus moved into sole lead.
