Annotated chess game

White's pawns are fatally weak. A "small" unbalance enough for white to lose the game after some good work by white. White should evaluate the possibility of Rd7-Ra7 to survive. IMO, of course!

I don't think this weakness is fatal...

This just bring the opponent (B) to get into the game his other piece (Rf8), while ours is still on f1, unactive.

Best seems to be 25,Rfd1, and then what for Black? E.g. 25...Rxd2 26.Nxd2! ... (forced, of course) 26...Rc2 27.Nf1! Bxb2? 28.Ne3 Re2 29.Kf1 winning. This line isn't forced, by any means, but it shows that White's Q-side pawns can be defended. Having said that, this knight move is rather clever, don't you think?

Yes!  

White should still win from here. Black's big disadvantage is that there are pawns on both sides of the board.

Still, it is the recommended asset: a B is stronger than a N when sided pawns are far from each other.

White has a N against a pawn's mayority of one on the Kside. I don't regard it as a W-must-losing situation. Say white manages to exchange the b and a pawns... a N could always be sacced for one or more pawns in order to draw. Not a "gimme" for black.

28.Rb1 freed the knight to improve its placing. If White absolutely had to move a pawn (you know, to stop the trembling hands) f3 seems more in keeping.

It looks as though the nerves are really setting in. 30.Kf1 was the caper.

A real pity. White was doing pretty well! Black's a pawn can't advance, and before the e pawn reaches e3, white has plenty of time to harass the black R with the K, once in e2. After that, the exchange of Rooks is all in white's favour, and black could resign!   (Right?)

White still has good winning chances, but with the Q-side pawns gone, it is a bit more... shall we say 'technical'.

That would not have been a good plan, since after h6, the WN just have to retreat. White has attacking moves like Rd7 (threatening Ne5), while the K can stand behind the pawns against the sole Black's Rook.

I don't think White should commit her pawns so quickly. I like 34.Rd7, here, also with the threat of Ne5 or Ng5. That will induce 34...Ra5, and THEN White plays 35.h4 h6 36.Rb7 (checking distance) ...Kf8 37.Ke3 with the manoeuvre Nf3-d4-b5-d6 in mind.

The pawns tend to obscure the Opposition situation, and you have to bear in mind the 'tempo' moves available to the rooks. It may be to early to talk of the Opposition quite yet.
