The Sacrifice
Seems Ur opponent did not concentrate on initial development and cramped himself too much.. I felt he could have recovered by playing more accurately.. Keep posting.. I enjoyed the review
No, sacrificing to unlock a position is completely wrong.
Why? I won the game.
So it is not "completely wrong", is it?
"Sacrificing to unlock a position is completely wrong?" I think every Grandmaster would entirely disagree with you. Kasparov did this many times, and he was arguably the best chess master ever.
Sacrificing itself is not wrong.. but Na3 took the N in to wrong position and then Black advanced the c pawn to c4 instead of cxd4.. so it created a sort of position for white to sac N.. Follow up by black was not as solid as it should have been.. many weak moves thereafter..
