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.Bc4 O-O 10.O-O)

This was played in the fourth round of the WORLD OPEN RAPID tournament that was held at the FIDE Online Arena on April 11th 2015. This was my second win in a row after losing five games in a row, so things seemed a little bit brighter at this point in time. There was one more round after this but the game below was the last one for me because in that last round game my opponent decided not to make any moves.
