The Position is just about equal in my opinion. So how and why did White Lose? the answer must be found deeper into the game.

No time to go into it properly, but it seems that white came out very well from his previous tangled situation, and I see an edge for white here, and I wonder when white will play Ne7+, almost forcing black to lose the exchange RxN - Qx7.

Yeah. 22. Ne7+ seemed to be a nice move. And what about g6 after Rf5?

Not 22...g6 23.Qxh6 gxf5 24.Nf6ch Qxf6 25.Qxf6, which looks winning for White.

Finally white does take advantage of the Bb7 being undefended...

...but only to find it is badly timed, since now black caught up the position

@jkarp: cavalry refers to horsemen.

@jkarp: Cavalry: the mounted arm of the army. Although the bishops were elephants and the rooks chariots, I tend to think of bishops as machine guns, and rooks and queen as artillery (or possibly tanks). The pawns are, of course, the p.b.i. - the 'poor bloody infantry'. It is the infantry, by the way, that are champion holders of ground in chess, as much as in 'real life'.

again just about equal with a slight edge for Black. The Bishop on e6 protects everything.Blacks position is airtight now.But White is safe. The Mystery continues.

I think this is a bad idea considering the fact that the black queen can now easily reach the white king. However, my rating is not nearly as good as either of the players so there may be a mistake that I am overseeing.

Black has one very tiny advantage here, I think: her bishop has a firm anchorage in the centre. It probably won't mean a whole lot in a B-and-Ps end game, but with Queens whizzing about all over the shop, well...

Why not go to c5? Seems like a more active square, threatens Qxa7 and Qc7 is also a nice move.

I think she would reply with Qb8 and we would go into variations similar to the game.

After 30.Qxa6, Black wins the pawn back, fairly quickly after 30...Qb8 31.e5 (say) ...Qb1ch 32.Kf2 Qf5ch (or ...Qc2ch) 33.Kg1 Qxe5, and bids fair to pick up another one as well. So 29...a6 is a very clever move!

If you took the pawn i would have gone with the Queen to g5. Much stronger.In fact going to b8 leads to a draw i believe.

Yeah. Qg5 also returns the pawn. The thing that gives slight advantage for black in that game is that a3, c3 and d3 pawns are all placed on dark squares. You see, as the white bishop moves along white squares, he will be less usefull when defending. That let's the black play combinations like a6.
