Время публикации: 24.09.2013 00:19 | Последнее обновление: 24.09.2013 00:19

The key game of Round 5 of Baku Open finished decisively. Alexey Dreev defeated the leader Nidjat Mamedov. Azerbaijani GM's decision to sacrifice a pawn after the opening (15...Nc6?) was inaccurate and brought him only problems. Another mistake was 19...Nb8? which led to a lost position, Dreev didn't give his opponent a chance to survival.

Now not only Mamedov and Dreev have 4 points out of 5, but also Alekseev, Smirnov and Zhigalko. Next round is tomorrow at 12:00 CET.
