14. h5-f7++ 

 If someone could PLEASE put this in an FEN format for me, it'd be highly 

appreciated.  I'm new here and not fully sure of how to do that stuff.  
The biggest mistake is when he doesn't act on my free pawn after I sac 

my knight.  I just analyzed my position from there and set him up. 

9. Qxd1 is winning for black

after 11. Bc4+ black only has to answer with Be6.

yes i saw that, but if 12 Bxe6 Kxe6 13 f7 never mind 13...Nf6 answers the threats & the BK will win the f7-pawn. White will be down the eqivalent of 2 pawns. Etienne is correct, Black's winning.

after another look i can't find a good answer to 12 Rd7+!! i believe RhinoFeeder has a brilliancy after all!!!

 Thanks.  I bet I'd be better if I wasn't so impatient with the game.  I'm young though so it's natural.  haha.

even if 8...Nxf6 9 exf6 White has strong threats against the weakened K position.

i did find an improvement for Black in the other line: 9...Qxd1+!(necessary) 10 Rxd1 Nh6!(not the "natural" Kf7) 11 f7+ Nxf7 12 Bxh8 Nxh8 & the position is virtually even.

then i went back to 8...gxf6 here 9 Qh5+! looks very strong: 9...Ke7(forced) 10 Rd1 Bd7(Qe1? because of 11 exf6+ Nxf6 12 Bxf6+ Kxf6[forced] 12 Qxe1 winning the Q) 11 Bc4 threatening mate on f7 & mate in 2 after Bh3+. So you did have a win earlier in the line anyway.

Looking back on this game I've realized the usefullness of a fianchetto bishop.  I'm a huge fan of this opening now.

 What about 10... Ke7?  Would he be able to come back from the heavy material loss?

i wouldn't want to be Black, but it is better than the game continuation. White can trade Qs & take the R, & should be able to trade-off at least one of his Bs with a winning endgame.

Still a fan?

Amazing
