I clicked on this thread and all I got was this lousy pic of a manga guy
ooh, what a hot chick

Insane ches i think the theme is that if black is passively developed and there is the bishop on d3, knight of f3, And queen in starting position against a regularliy castled king (no pushed pawns) the player should look for themes like this.
In order for there to be checkmate against a good defensive player, the f6-square has to be covered, usually by a pawn on e5. If there is a defender on f6 or if f6 can be occupied by a piece, then there are more defending chances. Also, the second Bishop is usually necessary to get a solid mating net.
Not saying your sacrifice here was a bad move. In fact, it was very correct IMO because of the e7-Knight. What I was saying is that Black would have had better chances if he had played 9...Kh6 and later N-g6 because then it wouldn't be a discovered check.
After 9...Kh6 wouldn't white follow-up with 10.e4
Or am I missing something?
This looks correct -- and even afterwards black has the simple 11...Kf6 with a better game. The sacrifice was unsound in principal, if it had worked I would have been amazed :)
are you talking about me? i feel concerned when people talk about me.
LOL.
