now i could simply win with Qb3, but i screw it up! i wanted to block the black bishop or exchange it so..the rook can move to b1

the silicon thinks nothing to fear and i am clearly better.. but to tell the truth i was afraid of f6 and i dont have a place to put my knight.

Qb3 is clearly superior! but i continue with my plan to put the rook at the b-file.

c5 and Rfg8 are better according to Rybka.

this is a bad move..now c5 make black life easy I just did not like to open the g-file. indeed Bxb4 is the right choice.

a mistake..c5 was the right one. Now i can take the knight.

now i get quality too..

well this sacrifice was because i thought i could not save my knight and not some brilliant calculation! Indeed i will destroy black pawn structure, get a pass pawn and create some attack opportunities too. Although Bxf8 is clearly better.

the natural move!

actually Qd6 and Kd7 holds my attack. Also the black queen controls the black square along h2 diagonal. A nightmare for my king.
