Annotated chess game

A move like Nd5 (not exactly now, but at some point of this stage of the game) loses a pawn, but it is better for white to exchange the deadly lsb.

This looks like the parting of the Red Sea...

  When the queen was still on f4, Nd5 "forces" the exchange (?)...

White might have tried 34.Nd5, but then black can shift his attention to the Q-side with 35...Qe5. The nice thing about controlling the center is that you can shift your focus from Q-side to K-side much more quickly than your opponent.

White wants to exchange the b pawn with the e one, but black don't fall for it.

Ne2 or Re2... but white is lost anyway.

Black's other threat (...f4 and ...f3) also has to be dealt with.

Finally white plays "the" move, but it is far too late, since it doesn't force the exchange.

White should have tried Qf3, trying either to exchange queens and blocking the f pawn. The N gets pinned, but his only duty is just to stay there, anyway!

On 46.Qf3, black bails out into a won endgame after 46...Qxf3 47.gxf3 Rxa5. White will not be able to defend his remaining scattered pawns. This was one of the lines that caused me to move ...Kg7 earlier, to prevent Ne7+ tactics.

47.Nxf4 Bxf4 48.Qxf4 Qxe2! and black is now ahead in material in addition to the crushing positional advantage.

What about Nxf4? BxN, QxN and black doesn't win. If Bxg2+, Rxg2, nothing changes... if Qh6, Nh3... can it be a move for white? ____ Wow! I wonder if white can play for a perpetual after that line (49. Qc7+, Kh6 - otherwise the queen can go on with more checks - 50. Qg3 - thinking in Qh4+ and that's perpetual. Black can go Bxg2+, 51. Kg1, Rd1... wow, it becomes complicated  

A well sustained positional attack. It is not all that often you see a game this length with the same theme persisting throughout. Excellent game!

Nice game and very good and clear annotation.

I can't find a mistake in neither the game nor the annotation, so congratulation. Very good game!

black resigns?????

Re-reading my comments, I think I am being very "pretentious", as if I was able to understand the subtelties of the position, and I were able to find better moves... I am aware I'm not, so please forgive me, thank you for standing me and for your answers. I think that I am the best candidate for a "walking the walk" game, since I just "talk the talk" all the time  

Thanks for the comments. I lost dozens of blitz and club games over the past couple of months figuring out how to play this variation, so it's nice to see that I actually learned something   @aailexx1, *white* resigns, I probably shouldn't do annotations at 1am. @damalfi, all your comments are welcome, don't feel self-conscious about proposing moves, I don't consider it to be pretentious at all. I'm sure there are variations I outright missed, and I'm also happy to explain the more subtle points of the position, after all I've had a lot more time think about it than you have.

I think in the variation you meant 51...Qf5!
