Marijan Petrov wins Vienna Open

Marijan Petrov won one of the stronger summer opens of 2011: the Vienna Open. The Bulgarian grandmaster edged out David Shengelia of Austria on tie-break after both had finished on 7.5/9.

The Vienna Open took place August 13-21 in the beautiful Vienna Town Hall. About 700 participants from over 40 countries played in four Elo groups: the A group for 2000+ players, a B group for Elo below 2000, a C group for Elo below 1600 and a D group also for Elo below 1600 but with only five rounds. There was also a blitz tournament (won by GM Evgeny Gleizerov) and a children's event. The rate of play was 40 moves in 90 minutes plus 30 minutes to finish the game, with 30 seconds increment from move 1.

After six rounds there were three leaders: Austrian GM David Shengalia, IM Egor Krivoborodov of Russian and GM Igor Khenkin of Germany. All three players had only conceded one draw thus far. Top seed Khenkin suffered a loss in the 7th round against another German grandmaster, Rainer Buhmann. By then a pack of seven players were in shared first place: the already mentioned Shengelia, Buhmann and Krivoborodov together with GM Mikhail Ulibin of Russian, IM Alexander Fauland of Austrian, GM Marijan Petrov of Bulgaria and GM Tomas Polak of the Czech Republic.

It got even more crowded at the top when the games at the top three boards ended in draws in the penultimate round. There was now a group of no less than 11 players with 6.5 points. Again several games finished in draws in the last round, but two players fought themselves outside and above the pack: Shengalia beat Hertneck on three, and Petrov defeated Khenkin on board one. Prizes were not shared in Vienna, so Petrov took home the full 2,000 Euros and Shengalia got 1,500.

In the B group, our friend and colleague Macauley Peterson (who, amongst many other things, produces the FEB) played an excellent tournament. He was fighting for the prizes all the time, and suffered his only loss in the last round but still pocketed a modest money prize.
