{ 00036.5.21 Analyzed by Candidate Master Daniel Waite } 1. e4 e5 2. Nf3 Nf6 3. d4 exd4 4. e5 Ne4 5. Qxd4 d5 6. exd6 Nxd6 7. Bd3 Nc6 8. Qf4 g6 9. O-O Bg7 10. Re1+ Be6 11. Ng5 O-O 12. Nxe6 fxe6 { So far you and your opponent have played "book"
moves. In other words these moves are already known. 
It is impressive that you and your opponent have
picked through the maze this deep into the game. You
need to be wary of being lead to the slaughter. Never
take on an opponent in their territory. You can avoid
the Petroff/Russian Defense with 3. Nc3. This will
get you back into lines you probably know and
positions where you are comfortable. At the very
least, you take your opponent out of his specialty. } 13. Qg3 { At this point you vary from "book." The old thought
is that the first to stray from the lines of the past
either gets their head handed to them or they have a
brilliant idea. In this case, you get your head. You
have many problems -> the open d - file, the half open
f - file, the non-development of the Queenside pieces,
Black's control of the middle, weak King position. 
(All tactics are based on positional elements.) 
Somehow you must buy some time to develop your pieces.
 Not to question theory, but you should go back and
understand how this line has led you to a miserable
position. BTW, this looks like one of those moves a
computer would make. } 13... Bd4 { Chess lesson #1: Black takes advantage of a "pivot
point." This is the square(s) that the Bishop uses to
attack the same side of the board that it sits on. 
Often we see a Bishop cutting across a diagonal but
the real danger comes from these pivot points where
suddenly it is attacking back across the grain. This
move is brought to you courtesy of your lack of
development. } 14. Re2 { Now your Rook is not on the back row. There is
nothing to defend against the back row checkmate. 
Whenever there is a weak King position, look for a
tactical shot. } 14... Ne5 15. c3 { Ouch, this is probably the only move that looses. 
You should have tried Bg5, Bf4, Nc3, or Nd2. When
your opponent has this much development on you, you
can not afford the time to chase pieces. Besides, c3
does nothing to move the Bishop of the "dangerous
diagonal" (the diagonal that bears down on your f2/f7
square). You are completely lost at this point. 
Chess lesson #2: Development is more important than
breathing! Chess in a sense is a war game where you
must mobilize your troops. If you do not, you insure
an easy game for your opponent. Again, this is
another computer like mistake. Play more live
opponents. } 15... Ne4 { Chess lesson #3: Pattern recognition. First, your
King is on the back row with no breathing room. 
Second, you have to deal with the open files. The one
that is going to seal your fate is the d - file. 
(Chess lesson #4: Always play in the center.) Your
opponent puts together two common patterns. } 16. Bxe4 { Pattern #1: The decoy. This decoy had the added bite
of actually creating extra possibilities on f2. } 16... Bxf2+ { Pattern #2: Clearing the file. Both of these are
simple to see if you know your patterns. Invest time
on learning these basic patterns. } 17. Qxf2 Rxf2 18. Rxf2 Ng4 { Chess lesson #5: Imbalances. An imbalance is any
difference in the position. At this point you are 2
Bishops & Rook verses Queen and Pawn. Not bad as far
as material is concerned. However, look at how the
Knight dominates both your Bishops and Rook. This is
called the "superior minor piece." In spite of your
material differences, you are playing a virtual Rook,
Knight, and Bishop down (pieces that have not been
developed). Black also has his pick of the d - file,
the f - file, and the a7 - g1 diagonal. } 19. Nd2 c6 20. h3 Nxf2 21. Kxf2 Qb6+ 22. Ke2 Qb5+ 23. Bd3 Qg5 24. Kf1 Rf8+ 25. Nf3 Qg3 26. Be2 e5 27. Bh6 Rf5 28. Rd1 Qf4 ?
