Annotated chess game

What happens if white goes here g4, and if fxg, f5, and if Bxf5, Bxh6+...? On the other side, if black doesn't takes the bite, g5, threatening gxh6+... could have been another "coup de scene"? (I mean "surprise")

Better late than never!

I think 22.Nxe4 would have been better for white

In charles's line, maybe (27.Nc3xe4! Rxg2) 23. Ng5+ can be interesting. Either black goes RxN, fxR, and black must resign to lose the Nd4 or Rxh6+ would be deadly, or black moves the K, which leads to a lot of complicated tactics. The lines I saw lead as a minimum to a full minor piece up for white, after a lot of complications. Kg6 allows Qh5+. Kg7 or h8 allow BxN+.

22...Rg6 should be played here! Gives black the upper hand!

In fact, Rg6 seems a more-than-enough defence. Black must be completely sure about what he is doing, because after the checks he will have to spend a move to defend the mate. Rg6 or Qd6 will do. With this in mind, black can adventure something of his own.

the only move for white

One of the R's is out of white's attack on the h column.

If I had taken the rook he would have mated me on h6.

Black can't capture the R because he will be mated Qxh6#. Black has no choice than check or defend.

White now has the advantage

This seems the deuce of a tennis game!  

Because his queen takes on h6 with mate.

Joe, Joe...

Better for white would be 25.Nd5 threatening Nf6+ with dire consequences

Dave, I am sure you are right, as always, although Nf6+ is not unstoppable, black has 25....Rg6 but then maybe 26. Nxc7

Rd1 would have been interesting. Black can't play Rd8 (to prevent Rd7+) because after RxR, QxR is not possible. But the whole thing falls because black has Bd3, blocking the R.

I would have played this a move earlier

Well said, Joe! Worse than that, if (say) black goes Rxa2 (a mistake, just to show the line), Nf6+ and if black doesn't play QxN (losing anyway soon after), NxRg8+, KxR (what else?) Qg6+ and mate the next.

I would have played this 4 moves ago Black would have a much better game

Big mistake by white?? he should have played 27.Rh3 then if 27...Rxa2 white plays 28.Rg3 and is winning!

Yes, how both sides had winning chances at various points is interesting...

Dynamic is right, of course. Black has no effective way to protect against all the threats.

White is now lost! Why he took the pawn on c7 I fail to comprehend! 27.Rh3 and he is still winning!

Patzer sees a pawn, patzer takes a pawn....

Well, in this case, this is also threatening the Bb2, and the Nc7 is now weak. If black can safely defend the R on g6 with Qf7 (say), black's safe against Rg3. Qf7 next will accomplish all that. It will take a lot of moves to white to bring the second R on the h file.

I did consider Qg8. The problem is he can play Qxf5 and that pins my rook on g6 so I can't take on g2.

I would say Qf7, so to block the N c7 where it is. That makes sure black's K. ON the other side, Qa3 threatens Rc1, and to protect it white has... Kh2, which helps black. RxN is just a loser.

My computer actually prefers e4-e3, as white does have a defence we both missed. Can you spot it dear reader?

No Joe. Re1, Rxg2#. Probably Rh2 prevents all, but white is lost anyway after Qa3.

Instead of 29. g2-g3, the computer likes 29. Qxg6! Kxg6 30. Rc6+. Presumably if Kf7 then Rf6 wins back the queen, so 30.....Kh7 and then the computer gives Ne6! with a large advantage for white.

I can't see the advantage. After 29. Qxg6! Kxg6 30. Rc6+, Kh7, 31. Ne6! we'll have Ra1+, 32. Kh2 (what else?), RxRh1+ (Nf1+?, RxN!), 33. KxRh1. Here, white is -5, and presumabily he will recover a piece and probably win the black's b pawn. I've looked, but despite white has a lot of firepower on the black K, it seems that with Qb4 black can't get mated, and if white stops the checks, (it can be for one of two reasons: 1) to play fxN, finally cashing the dangerous N, and 2) to prepare a mate threat on the BK), black will play Qe1+ and will draw after Qh4+.

Yes Joe, well done!

In fact my computer prefers leaving the rook there and playing 30....Qg8! with an overwhelming advantage to black.

The R is defended by a N which is "en prise", but Rxf2 will solve that issue.
