  goldfarbdj: Pretty easy, even for Tuesday. White would like to fork king and rook, but has the problem that his queen is en prise. So the queen goes forward instead of back: 28. Qxg7+ Qxg7 (only legal move) 29. Re8+ Qg8 (not Rxe8 30. Rxe8+ Qg8 31. Rxg8 mate) and now white can play 30. Nf7+ Kg7 31. Rxg8+ Rxg8 31. Nxd6 and end up a piece ahead.
May-03-11  VincentL: "Easy"

This I see instantly.

28. Qxg7+

Then 28....Qxg7 (only move) 29. Re8+ Rxe8 30. Rxe8+

(a) 30.....Qg8 31. Rxg8 mate.

(b) 30.....Qf8 31. Rxf8+ Kg7 32. Nxf5+ Kxf8 33. Nxd6 winning.

I must admit I only saw 32. Nxf5+ when I came to move 32.

Time to check.

May-03-11  APatzer: Found Qxg7+.
May-03-11  VincentL: Ah....no! My "solution" is not correct. Black can play 29....Qf8!

It must be 29. Rxg7 Kxg7 30. Nf5+ Kf6 31. Nxd5 emerging a piece up.

Not so easy.

May-03-11  VincentL: I only saw Qf8 when I moved the pieces. Shows what a difference this makes.
May-03-11  sevenseaman: 28. Qxg7+ has an easy follow up. A good Black could even resign, seeing mate lurking clear as day.

The only thing difficult about today's puzzle is to decide whether one is a Russian and the other an Italian. The names suggest I could be right there too... but its just a punt...

...the kind I keep taking every day whether the car in front will turn left, right or keep going straight, always catering for the odd chance it may come to a dead stop against an invisible elephant.

May-03-11  Sydro: 28.Qxg7 Qxg7 29.Re8 Qg8 or 29...Qf8 white has 30.Nf7+ picking up the rook on d6 after capturing the queen.

  Phony Benoni: By the way, after 28.Qxg7+ Qxg7 White has to play 29.Re8+, since 29.Rxg7 allows 29...Rxh6.

  Dr. Funkenstein: VincentL

If 29. Rxg7 then 29. ...Rxh6 keeps things level although 30. Ree7 is annoying, I don't think it does more

I think it's

28. Qxg7+ Qxg7 29. Re8+ Qf8 (29. ...Qg8 30. Nxg8) 30. Nf7+ Kg7 31. Rxf8 Rxf8 32. Nxd6 ending up with the extra knight.

  dzechiel: White to move (28?). Material even. "Easy."

Lots of candidate moves here, but I think the easiest win is

28 Rf7

Threatening to take the queen with check. Black has no good reply, but if he wants to stay in the game, he should probably play

28...Rg6 29 Rxf8+ Rxf8 30 Qf4

and black is down a queen for a rook.

Time to check and see how this ended.

=====

Ohhhh-kaaay... The text leaves white up a knight and a pawn (four points) about the same difference between a queen and a rook.

Let's see if anyone else saw my move.

  dzechiel: I'm still not sure why black didn't play 29...Qf8 in the game. I suppose I should read the kibitzing.

  dzechiel: OK, I suppose after 30 Nf7+ Kg7 31 Rxf8 Rxf8 32 Nxd6 white emerges from the combination a knight ahead (but that's only three points).

Too many ways to win this one it seems.

  dzechiel: OK, this is really embarrassing, and I need to post this before someone else calls me on it (although I think I see a line forming over there...).

Yes! My original key move 28 Rf7 is a loser, as the white queen is threatened by the pawn on f5. DUH!

I'll take whatever punishment the kibitzers deem appropriate. <sigh>

  Phony Benoni: <dzechiel> I think the only proper punishment is for you to run a blitz tournament on May 14th.
May-03-11  rilkefan: I saw this more or less immediately, but was slowed down a bit by the distance of the sting from the initial sac given that it's Tuesday, also the relatively small material won - it might have been easier labelled a Wednesday.
May-03-11  ComboKal: I like to play out these games from the start to see where the mistakes were made. 10...f5 seems to be where things go wrong for Cugini. After the pawn exchange and 12.f5... then the bishop swap, black is a pawn ahead. This is not worth the price of leaving the king wide open and vulnerable. It leads to the types of positions that we see in today's puzzle. 14.Nh4... wins the pawn back for white anyway.
May-03-11  sevenseaman: <dzechiel> <I'll take whatever punishment the kibitzers deem appropriate. <sigh>>

Why think of any further punishment; your going wrong is pleasure enough.

May-03-11  rilkefan: <10...f5 seems to be where things go wrong for Cugini.>

8...d5 looks awful to me - maybe ...a5 and Ba6 is slow, but black ends up just waiting to be slaughtered in this line.

May-03-11  ZUGZWANG67: Okay. It took me longer than usual.

Material is even. Black is pressed on the K-side. The WQ is under attack but the WRs are very active and the d6-rook is hanging.

My candidates are 28.Nf7+, 28.Qxg7+, 28.Rxg7, 28.Nxf5.

The only one that I found likely to achieve anything positive is 28.Qxg7+ but it took long to realize how it could be done. I think that there are 2 important points here, namely:

The d6-rook is not defended and;
White must use the right move order

Here's what I have:

28.Qxg7+ Qxg7 29.Re8+ and:

a)29...Rxe8 30.Rxe8+ Qf8 (30...Qg8?? 31.Rxg8 mate) 31.Rxf8+ Kg7 32.Nxf5+ and 33.Nxd6 leaves W a piece + a pawn ahead;

b) 29...Qf8 30.Nf7+ K-move 31.Rxf8(+) Rxf8 (or 31...Kxf8) 32.Nxd6 and W is still a piece ahead

c) 29...Qg8 30.Rxg8+ Rxg8 31.Nf7+ Kg7 32.Nxd6 with a piece ahead for W.

Let's see now...

-----------

I don't know why but I had to work on this one. I guess that' s part of my learning process...

Peace!

May-03-11  M.Hassan: "Easy" White to play 28.? Equal

28.Qxg7+ Qxg7 forced
29.Re8+ Rxe8
30.Rxe8+ Qf8 <if ...Qg8 31.Rxg8#> 31.Nf7+ Kg7 or Kg8
Queen is pinned and can not take Knight
32.Rxf8 Kxf8
33.Nxd6
White ends with a Knight up and can destroy pawn structure of Black and can win

White to play (28.?) "Easy"

White has a commanding position, but his queen is attacked -- a point which I missed at first, thinking that 28. Rf7 won! Thanks to White's superb piece placement, combined with the unfortunate placement of Black's pieces (especially the undefended rook on d6), White wins with a combo.

28. Qxg7+! Qxg7 29. Re8+!

Originally I looked at 29. Rxg7 Rxh6 (the poor placement of the Rd6 shows after 29...Kxg7 30. Nxf5+, winning the rook back with profit of a knight) 30. Rf7 Rh5 31. Re5 Kg8 32. Rexf5, winning a pawn and eventually the game, but that seemed kind of involved for a Tuesday... and then I saw what I was missing!

29...Qf8

Or 29...Rxe8 30. Rxe8+ Qf8 31. Rxf8+ Kg7 32. Nxf5+ Kxf8 33. Nxd6 is even simpler.

30. Nf7+!

This zwischenzug, combined with the pin on the queen, wins a piece when the dust settles.

30...Kg7 31. Rxf8 Rxf8 32. Nxd6 and White wins easily with an extra piece.

Don't feel too bad... I was thinking the same way for awhile! We both suffered what I call "chess blindness", but I looked long enough until I got my sight back! Even then, I didn't see the winning line for far too long for a Tuesday.

May-03-11  M.Hassan: <dzechiel>:Reward for honesty and integrity is not punishment and I salute you.
May-03-11  IRONCASTLEVINAY: I actually lost my mind . I failed to find move. It was easy.
May-03-11  LIFE Master AJ: I got stuck on this one. (01:24 AM)

I saw the aack on g7 - but for some reason, I nearly rejected it. I started to go with 28.Qf4, but decided to go back for one more look ...

I am afraid I totally lost track of the time again, the only thing that I am certain of is that I far (FAR!) exceeded my self-imposed mandate of three-to-five minutes ...
