Question in the Old Indian

So last night I face a 2300 player in an Old Indian Defense and he insists he was better all game until the very end where I missed a win in a time scramble.  He claims my 10th move was bad.  I still claim it is not.  Any masters on here have any incite on whether my 10th move, stealing the idea from "Play Unconventional Chess and Win", is "Inspired or Drunk"?

Ruben72d, sorry about the delay.  Cell phone compatability sux at this site and the first time I ran into the 30 minute error, so I lost the diagram 70 plus moves in.  Should be there now.  At the tournament, so do not have my lap top on me.

12.cxb cxb 13.Ne1 looks uncomfortable for Black: Both the a8 rook and the b5 pawn are threatened, and 13...Rb8 14.Be3 leaves white with pressure against the queenside.

Thanks pfren, I will have to look at that. Do you think there is any way to take advantage of the move order by White? Or just play the same normal moves and eventually transpose?

Well, I have not looked at the position in depth, but I guess the usual plan with 10...Bf8 etc would be more prudent. I do not think white's move order is defective, say:

It seems to me that white won because he is much the stronger player, and not because of the opening.

One last question pfren. Does Black have to wait for e4 by White, shutting the Bishop, before he can execute the ...a6, a4 a5 idea? I have seen it occasionally with the diagonal open by the Bishop. Just not sure when to do it unless e4 has been played.

In most cases after ...Bf8 the move ...e5-e4 by Black is a serious option. How long white can afford omitting e2-e4?

The computer claims that Black has full equality after 14...b5.

Thanks again pfren.  First time I have logged on since the previous post, and oddly enough, I face it again!  I put pfren's previous analysis to the test and this one wasn't as pretty.  Probably will play 10...Bf8 next time.
