This is the game I spent the most time looking at:
What's most interesting is the combination that begins on move 19 (19 ... Bxe5). My copy of Rybka assures me that this isn't an awesome move (white should just play 19 ... Bxe5 20 dxe5 Nxe5 21 Ba3), but I supsect most people on this site wouldn't even have considered it.
And the whole opening shows a pretty good understanding of this kind of set up (especially getting in the f5 idea).
1) absolutely no self confidence and are better than you think you are
2) you playing mind games with us
3) you're getting help (note that this game doesn't show signs of computer help)
Regardless, its not credible that you've just played a few games with your brother
