B30 Sicilian: 2...Nc6 3.Bb5, lines without ...g6 (1.Nf3 c5 2.e4 Nc6 3.g3 g6)

When a bit tired and feverish one should not play chess and I was both yesterday evening when I went through some of my games. I ended up messing up a completely winning position with one really careless rook move. I do not know what part of my brain snapped at the time and made me think that the move I am doing would be good. Because of that rook move I am no longer winning and I might be a bit worse actually though I may still have some hope for a draw. The game I am sharing with you now is quite a new game played at Chess.com not that long ago. The opening features once again unusual move order like so many times before in my games. This time of course the move order is not that big, you only need to change white's second move to be made in move one and vice versa to get the move order that is in opening theory. Mate in one, two, four and five puzzle pages of the blog have been updated today.
