10 runda Grand Swiss, wielka smuta u Panów

Dwie ostatnie rundy w turnieju rozgrywanym systemem szwajcarskim są decydujące jeśli chodzi o lokatę końcowa. Niestety, przedostatnia, 10 runda Grand Swiss była dla Mateusza Bartla i Radka Wojtaszka pechowa. Obaj przegrali, szczególnie szkoda ruchu Radka 33...Kh7 bo to jego pierwsza porażka w turnieju.
