Pavel Eljanov made a decisive step towards qualification in the next round at his game against Alexander Grischuk at round three of the World Cup in Baku. The Ukrainian Grandmaster was the only player to win his game with the black pieces and remains the only player with perfect score in the classical chess 5/5! Both players gambled, but Eljanov got luckier.
