I recently played an email 2.a3!? game with a friend in Ireland. It was a lot of fun, but frustrating, as I missed some basic ideas in the positions, and often felt like my game with White was like a balloon with its air slowly leaking out.
Rory and his trusty computers annotated the game for me; Later I added Fritz8 comments, which sometimes vary.

Hi Rick. I've had a fairly good look at the game now and as you will see there are a couple of moves that seemd to alter the evaluation greatly. More than this though when it goes to show how inaccurate computers are. Several time I went down the computers suggested line only to find that actually it was crap. You really have to hold the comps'. hand and 'walk it' through. This in actual fact makes computer assisted analysis longer!

When I was playing I felt that this was the critical positon, but as the analysis engines show there is huge variation in white's percieved advantage, what they all agree on though is that white is winning. 9.Ba3 [Fruit 2.2: 9.c3 Na6 10.Bf4 Bh6 11.Qc1 Bxf4 12.Qxf4 Ke7 13.Bd3 h6 14.Qh4+ Kf8 15.00 Kg7 16.e5 g5 17.Qh5; Shredder 9.1 UCI UCI: Nolan,Rory: 2.00 Shredder 9.1 UCI UCI: 9.c4 Qc6 10.Ba3 Bf8 11.Qb1 Na6 12.Bxf8 Kxf8 13.Ne5 Qb6 14.c5 Nxc5 15.dxc5 Qxc5 16.Qb2 f6 17.Nd3 Qb6 18.Qb4+ Kg7; Deep Junior 7: 9.Bf4 Qc6 10.Bd3 (10.Nd6+ Nolan,Rory 10...Kf8 11.c4 f6 12.Qb3 Na6 13.c5 Ne7 14.Bb5 Qc7 15.Bg3) 10...d5 11.Nc7+ Kd8 12.00 e5 13.Bxe5 Bxe5 14.Nxa8 Bb8 15.Ne5 Bxe5 16.dxe5 Qc5 17.Qf3 Be6 18.exd5]
