Long time chess playing friend of mine, Milan Ninchich, sent me a couple of games that he played in the 2007 Doeberl Cup. Now while most players are happy to submit their glorious victories, Milan submitted a lucky draw and an unlucky loss. In his email to me he said "they may prove educational and lowly rated chess players hardly ever get there games published".
So I figured to publish at least one of the games, and decided to add some of my own notes (I hope he doesn't mind). With the aid of Fritz 7 I went to work. When I finished 90 minutes later, I had attached far more analysis than I had intended to. But I guess this is a consequence of Computer Aided Analysis.
In the BC (Before Computers) era, analysis was far more general, and in adding long variations, you ran the risk of having embarrassing holes pointed out. But on the flip-side, the post game analysis matched much more closely what the players were probably capable of seeing during the game. Now anyone with a half decent computer and program can dissect an entire game, pointing out where wins were missed, even if that conclusion might not be clear for 15 or 20 moves.
The following game is a perfect example of this. White misses a Rook sac on move 19 which would have given him a better game, but only after a sequence of "only moves", moves that I for one would not have been able to find. And if I was White I would have only looked so far into the position before confusion over took me, and would have then chosen a much safer reply.

1.e4 e6 2.d4 d5 3.Nc3 Nf6 4.e5 Nfd7 5.a3 c5 6.f4 Nc6 [6...cxd4 7.Qxd4 Nc6 is more assertive than Black's actual choice.] 7.Nf3 cxd4 8.Nxd4 Nxd4 9.Qxd4 Bc5 10.Qd3 f6 11.Be2 0–0 [11...fxe5 turns out to be a little too dangerous for Black. 12.Bh5+ is the obvious idea. 12...g6? (12...Kf8! 13.Qg3 e4 and although his position is uncomfortable, Black still has an extra pawn.) 13.Bxg6+ hxg6 (13...Kf8 14.Qh3 e4 is equal according to Fritz 7) 14.Qxg6+ Ke7 15.fxe5 Nxe5 and now White has to play accurately to justify his sacrifice. 16.Qg7+ Kd6 17.Bf4 Rh5 18.Ne4+!

Black seems to be winning here.) 30...Qg1+ Black seems to have nothing better than a draw. 31.Kd2 Qg2+ (31...Qxa1?? 32.Qh7+ Kg5 33.Qh4#) 32.Ke1 Qh1+ 33.Ke2 Qf3+ 34.Kd2 Qg2+ 35.Ke1=) 24...Rg7 25.Bh6 Ne5 26.Qh7!!
