12...Qd8 13.h3 0-0 14.Nb3 Bd6 15.Rb1
Garry can't 0-0-0 now, and Black will lose the a-pawn. Black must counter-attack on the kingside... will it know that? [15.cxd6 Nxb6-+ ; 15.Nxa5 Nxb6! 16.cxb6 Bxa3 17.Qxa3 Qxb6-/+ ; 15.Bb4 Nxb6-/+ ]

15...Be7
Whoa! A huge loss in time for Fritz! Where's the counter-attack on the kingside? Or is the point of Bd6-e7, white now cannot 0-0-0, and the Be7 may have Bh4 later? Nah... the computer just does not know how to play these closed positions.

16.Nxa5
Now Bb4, Queen back to b3 or c2, and then push the a-pawn. The computer must generate some counter-play with f7-f5-f4

16...Nb8
With what idea? Black has made no progress at all... the pieces ae back on their starting squares. Na6?! is not the right plan... Black needs counter-play on the kingside. Perhaps ...Qd7 and Qf4

17.Bb4 Qd7 18.Rb2
the a1 square is open for king safety... Black needs to play f7-f5-f4, but there's no sign of it. Rb2 assists the kingside defense. White can now consolidate with Qc2 and a3 (or even a4).

18...Qe6 19.Qd1 Nfd7 20.a3
next is Nb3, consolidating the extra pawn. Fritz finally figuring out that f7-f5 is needed for counter-play? 20 moves and Black has barely developed only three pieces.

20...Qh6
The computer begins its attack. Now Qh4, or f5-f4 next.

21.Nb3
Releases the pressure on b7, but frees up the a-pawn to advance. Will Fritz respond with Na6 to stop a4? And can Gary make Nxd5 cxd5 c6 work?

21...Bh4
A simple cheapo threat, Qxe3. White must stop the threat, probably with g3 or possibly Qd2. Gary won't overlook this one!

22.Qd2 Nf6
Very poor! A human knows to get the f-pawn rolling. What is the poor knight to from f6? No need to play g3 now, which would only be needed after f7-f5.

23.Kd1
Moving the king towards the safety of a1-b1 and stopping any possibility of Ng4. Great opening by Gary! The computer is completely lost here!

23...Be6 24.Kc1
When the king gets at a2 (for full safety), white can consider an attack on the kigside with f3!

24...Rd8
no plan at all here. The rook needed to stay on f8 to support f7-f5-f4. These Black moves are not part of a coordinated plan. Now Kb1-a2 or a4-a5.

25.Rc2
Very nice technique. The idea is Kb2 (it's very safe on the dark square and not on a2) and then perhaps Rc1 with the idea of g3 and h4)

25...Nbd7
No need for white to rush, but Na5 looks strong here. But the better plan for white is Kb2 and then a4-5-6, perhaps also with Nxc6

26.Kb2 Nf8
again, no point. How about a4, Gary? Or perhaps Rc1 with the idea of g3 and h4 or Rc1-a1 with support of the a-pawn push

27.a4
On chess.fm, Fedorowicz predicts a5, Na2, Bc3, Nb4 and a6. Looks like a simple, solid plan.

27...Ng6
With what idea? ...Ne5??

28.a5 Ne7
aimless play by Fritz. Slow plan now with Na2-b4, or a6 straight away with Na5 to follow

29.a6
Black has to capture here with ...bxa6, but Garry gets a protected passed pawn. Then Na5 or Ba5 with the idea of Na2-b4 crushes.

29...bxa6 30.Na5 Rdb8
Now just bring the Nc3 to b4 and the game ends

31.g3 Bg5 32.Bg2
Very cruel play by Gary. Now the Rh1 will join the queenside attack on a1 or b1. The immediate threat is h4 winning the Bg5

32...Qg6 33.Ka1
Taking the K off the b-file, avoiding sacs on b6 and the idea of Ne8-c7

33...Kh8 34.Na2
Kh8 is more of the same. Na2 will go to b4 after Bc3 or Ba3. Gary can also play Rh1-b1 and the Bg2-f1. It's over folks!

34...Bd7
Fritz sees the Na2-b4 after c3 and is trying to over-protect the c6-pawn.

35.Bc3
and after Nb4, Ra2! puts more pressure on the a6-pawn.

35...Ne8
no idea here either... no sacs in the air (Nd6?). Nb4 coming.

36.Nb4
Ra2, Bf1, Qe2 are all in the air. A human might resign here. How about Ctrl-Alt-Del?

36...Kg8
Harumph. Another meaningless move by Fritzy.

37.Rb1 Bc8 38.Ra2 Bh6 39.Bf1
Now Rb3-a3, or Qe2, or Nb3 and Ra5

39...Qe6
with the defensive idea of Bb7 and Qd7

40.Qd1
with ten seconds to go before the time control

40...Nf6 41.Qa4 Bb7 42.Nxb7 Rxb7 43.Nxa6
and now Qa4-c2 and Nc7. A GM would resign here...

43...Qd7
Qc2, with the idea of Rb3-a3

44.Qc2 Kh8 45.Rb3
Certainly no hope here. White mops up with Rba3 and Nc7. Well done Gary! 1-0
