4/20/2019 – After starting off with two straight wins at the GRENKE Chess Open, Iranian prodigy Alireza Firouzja decided to forfeit his third round game as his opponent was an Israeli national: FM Or Bronstein (pictured). The laws of Iran forbid Iranian players from playing against Israelis. Had Firouzja played, he would have risked facing sanctions back in his home country. But forfeiting a game also cost him dearly — as ADITYA PAI reports from Karlsruhe — Firoujza seemed to have lost his composure in the next round as he simply left his rook en prise against 1945-rated Antonia Ziegenfuss (pictured). Surely one of the biggest upsets we'll see this year!
