B33 Sicilian: Pelikan and Sveshnikov Variations (1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 e5 5.Nb5 d6 6.a4 a6 7.N5a3 Nf6 8.Nc3 Be7 9.Be2 O-O 10.O-O h6 11.Be3)

The game below was played in the first round of the WORLD OPEN RAPID tournament that was held at the FIDE Online Arena on April 12th 2015. It is always good to start with a win in which I am never really on the losing side. I did many inaccurate moves but they never handed the advantage to my opponent. There are no reference games in a different publishing tool this time since there were no high rated games that reached the position after 11.Be3. I did find three games on my reference database, but the ratings of the players were not shown there, so I did not choose to put them to this post.
