Now, if play had continued as in the text with 28...e5 29 f4 Rg4, then 30 Kh3, below, prevents 30...Rxh4+.

You are correct. While the combination was four moves deep, the analysis tree had only two branches (32 Bxh4 and 33 Kf1) which both ended in an immediate checkmate.

All of black's moves were with check and, as such, were very forcing, making the solution available to even novice solvers.

31. ...Rxh4+ 32.Kg2 (32.Bxh4 Qxg1+ mate; 32.Bh2 Rxh2+ 33.Kxh2 Qxg1+ 34.Kh3 Qh1+ is also mate) Qxg3+ 33.fxg3 (33.Kf1 Qxg1+ mate) Rxg3+ 34.Kf1 Rxg1+ is mate. Here the BB is playing an important role in watching f2 and g1! Idem for the f4-pawn! Cool combination!

32. Kg2 Rh2+
33. Kf1 Rf2+ (or 33. Kf3 Qg4+ 34. Ke4 f3+ which clearly wins)

34. Qxf2 Bxf2 (or 34. Bxf2 Qxg1+ 35. Bxg1 Rxg1 mate)

35. Qa1+ Be1
36. Rxg1+ Kxg1
37. Qxe1 with a decisive advantage

Correct one is 32...Qxg1# (White Bishop cannot capture the Black Queen because White Bishop on h2 is pinned by the Black Rook on h4). 0-1

They give White as:
Iuldachev, Saidali (2550).

This game was featured as the "Problem of the Day" (daily puzzle) for Wednesday; October 14th, 2009. [ Note: I am trying to analyze many of these games ... however, I am too much of a perfectionist. (I can spend days - or even weeks - trying to fine-tune my analysis.) ]

Note that the CG website spells the first player's (last) name as "Yuldashev."

1.e4 c5; 2.Nc3 Nc6; 3.Bb5 Nd4;
The main line, according to the PB.

4.Bc4 e6; 5.Nf3 Nf6; 6.0-0 a6; 7.d3,
The first choice in the Fritz "Power-Book," however -- I would have preferred a move that did not cost White his crucial KB (light-squared ♗) ...

[Maybe 7.a4, " " was OK for White?]

7...b5; 8.Bb3 Nxb3; 9.axb3 Bb7; 10.e5 b4!?; 11.exf6?!,

Looks right ... ... ...
but winds up costing White any chance for an advantage.

[Probably the continuation of: 11.Na4 Nd5; 12.Ng5!, " " was a little better than the game.]

11...bxc3; 12.fxg7!?, hmmm

[Or 12.bxc3 Qxf6; 13.Bb2, ∞.]

12...Bxg7; 13.bxc3 Bxc3; 14.Ra4 Rg8; "∞"

This position is pretty close to equal, at least for the moment.

15.Bf4!?,
A natural-looking move, however, this seems to get White into trouble. [Maybe '?!' (dubious?) here?]

[The box prefers: 15.g3, '=' for White, in this particular position.]

15...Qf6; 16.Bg3 Bxf3; 17.gxf3?,
This rupturing of the K-side and allowing the ensuing assault has "SUICIDE" written all over it. (The normal rule of thumb is to exchange Queens in such a position ... in order to lessen Black's attack.)

[Instead, White should have taken his chances in the endgame, after: 17.Qxf3 Qxf3; 18.gxf3 d5; " " but Black is clearly better. ]

17...h5; 18.Kh1 Bd4; 19.h4 Ke7; 20.Qe2 Rg6!!; 21.Rg1 Rag8!;

The Black a-Pawn is not important.

22.Rxa6 Kf8!; 23.Ra4, Hmmm.
I guess White wants to play b2-b4, not that the Pawn move really does a great deal for White's game.

[RR23.Kh2 d5; 24.c4, " " - Fritz 11.]

23...Kg7; 24.b4!? cxb4; 25.Rxb4 Kh7!; 26.Rg2!? Qg7;

Note the tripling on the g-file.

27.Rb5!? ,
White targets Black's RP ...

[Maybe better was: 27.Rb7 f5, "∞ ".]

27...f5 ; 28.Rg1?!,
A pointless move that only exacerbates White's troubles on the g-file.

[Better was: 28.Qd2 Bxf2; "=".]

28...e5!; 29.f4?,
After this move - which only further exposes the WK and allows the BR to come to g4 - White is lost.

[Better was: 29.Rbb1▢ Qf6; "/+ ".]

29...Rg4!;
With the idea of ...RxP/h4+; and if White captures on h4, then Aronian can simply play ...QxR/g1#.

30.fxe5!?,
Now everything loses, so it is almost pointless to tack on more question marks. (Fritz shows that Rg2 was forced.)

[RR White had to play: 30.Rg2 Rxh4+; 31.Rh2 Rxh2+; 32.Kxh2 Qg6; 33.fxe5 h4; " ".]

30...f4!; 31.e6!?,
White plays for a simple cheapo. (RxP/h5+, Kg6; and then QxR/g4.)

We have now reached the position for the "Chess Games" daily puzzle or P.O.T.D.

[Fritz shows White's best line as: 31.Qe4+ Kh8; 32.Qxd4 Rxh4+; 33.Kg2 f3+; 34.Kxf3 Rxd4; " " (Black is still winning.).]

31...Rxh4+!; 32.Kg2▢, Forced.

[Or (worse is) 32.Bxh4?! Qxg1#.]

32...Qxg3+!; " " White Resigns.
(The following moves were all forced: 33.fxg3, RxP/g3+; 34.Kf1, RxR/g1#.)
