B76 Sicilian Dragon: Yugoslav Attack, 9.g4 and 9.O-O-O (1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 g6 6.Be2 Bg7 7.Be3 O-O 8.f3 Nc6 9.Qd2 Bd7)

This was played in a team match called Rematch. It was played on 47 boards between LATINO and Space Angels Celebrate Thanksgiving For All Angels In Andromeda's Cluster Of Infinite Bright Stars. I played on board 11 for Space Angels Celebrate Thanksgiving For All Angels In Andromeda's Cluster Of Infinite Bright Stars and in addition to this loss, I won my other game against cedula1066. The final result of the match was 37.5 - 56.5 in favor of Space Angels Celebrate Thanksgiving For All Angels In Andromeda's Cluster Of Infinite Bright Stars.

There was only one truly critical moment in this game and that you can see below. It is taken after the move 13...Rfc8.

I made a huge mistake in the position and played 14.Bh6?? I have seen similar exchange sacrifices on c3 like the one my opponent played in this game before, but for some reason I was not aware of the danger in this game. I should have played either 14.Nb5 or 14.Nd5 instead. I think I would prefer the latter if I were to end up in this same position again. My 14th move was the move that cost me the game and the game ended quite quickly after that.
