One move a day (2)

Also, it seems that, after 9. d4, the f4 pawn will fall.

Yes, which is not as clear after 9.d3, because that move isn't forcing on the queen, giving black a tempo to play, for instance, Bh6 after which white wouldn't want to play Bxf4 Bxf4 Qxf4+ Qxf4+ Rxf4+ winning the f4 pawn but losing the game.

Very true. Correct me if I'm wrong, but White can't afford to exchange the queens, unless if it's in a mating combination, or it will weaken the attack.

Well 9. d4 leaves b2 undefended but that doesn't really matter. 9. d4 Qxd4 10. Be3 Qxb2 11. Qxf4+ Nf6 (11. ... Qf6? 12. Qd4+ and black loses his queen while white gains more tempos and his bishop remains active and black's development still isn't that good) 12. Bd4 and black is in trouble (IMO he already is). Supposedly, black will play 10. ... Qg7 (10. ... Qf6? 11. Qd5! and f4 falls). Probably I haven't mentioned something important but I also think it's going to be 9. d4.

Let's not run ahead too far, but after 9.d4, 9. ... Qxd5+ is not forced, let alone the 9. ... Qxd5+ 10.Be3 Qxb2 .... We will find out in the coming days.

I have played almost every variation of the KG more times than I can count (with the exception of the Keiseritsky(sp?) ) and I haven't found any move better than 9.d4. I am only about 1700 on here but experience has to count for something.

white has committed two pieces to this attack.

material no longer matters.

d4.

d4. This is all about the f-file and white's already committed to the attack. c3 seems too slow. White's got to get the bishop and other pieces out.

1. e4 e5 2. f4 exf4 3. Nf3 g5 4. Bc4 g4 5. O-O gxf3
6. Qxf3 Qf6 7. e5 Qxe5 8. Bxf7+ Kxf7 9. d4

The obvious move is 9..Qxd4, as has been discussed. One move I wonder if it would be playable is: Bc5!? with the idea of giving back a piece in return for keeping the f-pawn a little longer and slowing white's attack.

Any thoughts?

I think this is where Black has to break out of the main line and play...

Qf5.

Qf5.

9. ... Qf5 is the mainline, and much stronger than Qxd4+. It allows black to reserve the f6-square for a piece rather than his queen . Instead of Qxd4+ Be3 Qf6 Bxf4 now Qf5 Bxf4 Nf6 becomes possible. This may be a crucial factor in the later defense. Of course, white is not forced to play 10.Bxf4 .....
