I started a forum on 9. b4. What was said there was that after 9... e5 10. b5 exd4 (rather than your 10... Na5? 11. dxe5 Nxc4 12. exd6 Nxd6 13. Qe2 where all of White's pieces will become better placed than Black's.)
Then IM pfren's 11. exd4 Na5 with a perfectly okay IQP for White, however the b5 pawn is a weakness rather than a strength. White will have to play some kind of minority attack with b6 or a5-a6.
Well, the next set of games is coming to a close, and it's looking like chesster's going to extend his lead. This one went my way, though.
29... Qa1 was a mistake, I believe, and then after Qe4 the only response is Qa3. But then if we trade off everything my passed pawn should be winning - I think? I think chesster had to play 30... Qa3 31. Re8+ Rxe8 32. Qxe8 Qf8... which at least keeps a rook on the board. Now someone wiser than me can come along and tell me what I did wrong 
10.5-7.5.
You tried the Nimzowitsch Defence this time! Was that a surprise attempt or just an experiment?
You were dead after 15. d5, but what's funny just how lost your position is in the final position. You're essentially a rook down, because the Rb4 isn't going anywhere, and perhaps more, because the Bc4 isn't entirely a defender. Your king is in danger, and to stop h4-h5-h6-h7-h8=Q, you'll have to block the pawn with ... f5 and ... Rh7, because your king is unsafe. Then I have carte blanche on the center and queenside, and I can double on the e-file or on the 6th rank. I can even play a long game of Cat and Mouse with the amazing maneuver Kg2-f3-g2-f3-e2-d3-e2-e1-d2-e3-d2-e3-f4-e5-f4-e5-f6-g6-f6xe6. 😀
I just decided to do something different because I didn't want my games to all start the same again. Looks like I should have stuck to them starting all the same. There was nothing funny for me in the final position... 
And yeah, 31... Rb4 was an unbelievably bad move. I should be losing anyway, but that made it far too easy.
Well, game 19 is done, a draw. I have an extra pawn in the final position but I don't think I can do anything with it. Ready now for one of the local chess geniuses to come along and tell me what I should have done with it.
Game 20 is finished, a win for me. I'm coming out better from this set than I thought I would. I hate to say it, but I think chesster made a mess of this endgame.
The last in this group is finished, a draw. 57... b4 cost chesster the win. Kd5 and I can resign.
Getting this going again with the next set of five games. After 21 games the score is 11.5 - 9.5 in chesster's favor.
Go Theron! Btw, put some flowers on Fischer's grave for me.
Thanks, Pulpo! I will if I ever actually get to Iceland - it seems that's the only place in the world I've not been or I'm not going to in the next few weeks. I've appointed myself an Icelander in honor of their soccer team
Good! I would do the same in honor of it being a serious country, but yellow and red match so well...
Wait, is that why 3 months ago you were from Kyrgyzystan?
He's the man who would be king...
I have to agree. 27. Rc3 was better, blocking the third rank, after which I can just advance my pawns.
