IECC Pyramid

I have been actively playing games in the IECC. I particularly enjoy their pyrmaid ladder, so I have played several games in that format. This is the latest win for me in that area of the site. I am currently working on an annotation, but this version has a few notes in it.

[Event "P-4961"]                                           [Site "IECC"]  [Date "2015.02.26"]  [White "Mahony, Michael J."]  [Black "Jacob, Sheeju Urbanus"]  [Result "1-0"]     1.e4 e6 2. d4 d5 3.Nc3 Nf6 4. Bg5 Be7 5.e5 Nfd7 6. Bxe7 Qxe7 7.Qg4 O-O 8.Nf3 {Theory is to play 8.Bd3, but I purposely played this move order because in email games my opponent is allowed to consult books, publications and databases. My plan is to potentially throw him out of theory as soon as possible so that I can take advantage of the almost 800 rating points I have on him.} c5 9.Bd3 {Transposing right back into a theoretical position.} cxd4? {9...f5 was necessary to avoid what came next.} 10.Bxh7+! {This move opens up the attack that ensues. White has a clear advantage.} Kxh7 11.Ng5+ Kh6 {Safer was 11...Kg8 12.Qh5 Qxg5 13.Qxg5 with white still holding an advantage.} 12.Qh4+ {White now has a forced mate in 9 according to Aquarium.} Kg6 13.Qh7+ Kxg5 14.Qxg7+ Kh4 {14..Kf5 holds on longer, but it is still a forced mate.} 15.h3 Qg5 16.Qh7+ Qh5 17.g3+ Kg5 18.f4# {The moral of this game is that you should understand the opening you choose to play. Simply making moves because they are in a book or database is going to get you in trouble more often than not.}
