A00 Irregular Openings (1.b4 e5 2.Bb2 Bxb4 3.Bxe5 Nf6 4.Nf3 Nc6 5.Bb2 O-O)

A00 Irregular Openings (1.b4 e5 2.Bb2 Bxb4 3.Bxe5 Nf6 4.Nf3 Nc6 5.Bb2 O-O)

The variation looks very close to the one that was played in the game that I shared yesterday, the only difference being the 4th move from White. That being said, both games reach the same exact position after White's 7th move. The only difference then why they are in different posts is that 4th move and the fact that the last move that Deep Fritz 14 classifies as being theory is the position after Black's 5th move in both games. The game below was played on the third round of a tournament called Taraus-turnaus at Tampere in 2006. My worst chess playing year to date was getting to its end, I only played at one tournament after this and one team match in the last part of 2006. In the first two rounds I had only been able to get one draw and one loss. Losing this game only increased the downhill that my rating had experienced the whole year. Actually this tournament was actually my best over the board tournament in 2006 since I only dropped my rating six points... There was only one moment in this game where one of the players made a huge mistake that was enough to decide the game, unfortunately it was me on move 18, when I played 18...Nxf3+??

In this particular position making an in-between move like 18...Nxf3+ does not work because Black has too many pieces hanging. I tried my best to hang on, but after the reply 19.Qxf3 it should be clear that there is only one result that can come out of this game. I did play a few more moves, but I had to resign after 25.Rxd3 in a completely hopeless position.
