In this year’s Prague Chess Festival things do not go well for David Navara. In round 4 of the Masters he played against Nijat Abasov (pictured) and suffered his fourth loss in a row. Navara had an excellent position but first gave his advantage away and then lost on time. The other three games of the round ended in a draw. After four rounds Sam Shankland and Abasov now share the lead with 3.0/4 each. | Photo: Nijat Abasov (Vladimir Jagr)
