  agb2002: The material is identical.

White threatens 34.Re8+ Ka7 35.Qf2+ and mate in three.

Black can exploit White's weak back rank with 33... Qa4+ 34.Kb1 (34.Rxa4 Rxa4+ 35.Kb1 Rh1+ and mate in two) 34... Rh1+ 35.Qe1 Qxe4 36.Rg1 Qxe1+, etc.

  whiteshark: <33...Qa4+!>, and that's it.

  Oxspawn: Stared at it for ever so long and thought "If only I could shift the rook off e4 I could play Qa4+". Then I played the game through and when I saw 33. .... Qa4+ it looked immediately devastating, and suddenly obvious that 34. RxQ was futile .....what is the block in my brain that stopped me seeing this before the queen actually moved?
Jul-23-14  morfishine: <33...Qa4+> Many chess adjectives suddenly come to mind: "X-ray, Skewer, Double-attack, overload"

34.Rxa4 Rxa4+ 35.Kb1 Rh1+

One of things I like about chess is after such a catastrophe, one can have a good laugh, grab a fresh beer and set up the pieces again :)

*****
<OhioChessfan> True, White can prolong the game, but not by much: 33...Qa4+ 34.Kb1 Rh1+ 35.Qe1 Qxe4

*****

Jul-23-14  Chess Dad: 33. ... Qa4+
34. Rxa4 Rxa4+
35. Kb1 Rh1+

Nothing but delays after that.....

Jul-23-14  geeker: My favorite X-ray (on the a4 square) theme! Surprisingly, I saw this immediately.
Jul-23-14  zb2cr: Sweet. 33. ... Qa4+ does it. Now, if 34. Rxa4, Rxa4+; 35. Kb1, Rh1+. White has 2 useless interpositions on the back rank before checkmate.

If White tries to decline the sacrifice with 34. Kb1, Rh1+; 35. Qe1, Qxe4 (taking advantage of the cross-pin); 36. Rg1, Qxe1+; 37. Rxe1, Rxe1+ and Black is ahead by two Rooks.

Jul-23-14  Vinod S U: Incredible move by polgar 33.Qa4+, though i got it at the first site.. easy for a wednesday..

  Once: Here's the crunch position just after black has played 30...R8h4

White has an uncomfortable position, but it's not yet terminal. Black's rooks have been doing mosquito impressions on the h file. Buzzing, annoying, needling. Black also has a splendidly outposted knight which can't be easily dislodged.

For all that, it's not clear how black will break through. Fritzie reckons that the position is worth around -1.

I think that Judit is employing a tactic that my ex wife also perfected. It's not an outright attack. Instead it's a constant needling and annoyance until you crack and make a mistake.

She probably had her eye on the Qa4+ for some time. If she can safely get this move in, at the very least she ought to pick up the lonely a5 pawn.

In the diagram above, white goes wrong with 31. Nf3. Fritzie says 31. Rxh4 was best ... or should that be least worst?

The problem with 31. Nf3 is that black can exchange knights, taking away one of the defenders of the white position.

But I have to say that is certainly not easy to spot. 31 Nf3 seems such a natural move to kick away the annoying black rooks. You can easily see why white played it.

Jul-23-14  sfm: 30.-,R8h4(!!)
What a cunning b....
She knows perfectly well that White will play 31.Nf3??, a move that is good in every way, except...

  Penguincw: Hmm. I struggled forever on this puzzle, until I saw it was black to move, which I got. If 34.Kb1, 34...Rh1+ wins the queen (34...Qxe4 is probably good too).

  PawnSac: This is a cute little puzzle...

When I first looked at the game position I immediately saw ..Qd8 34.Re8? Ra4+ 35.Kb1 Rh1+ but realized it was only a "cheapo" because white could simply play 34.b4 and black loses the initiative. SO, then after i saw Qa4! i thought "Sweet. Judit.. darlin' you get a high 5 on that one!"

Jul-23-14  gars: Maybe old stuff, <Phony Benoni>, but I found it beautiful all the same.

  kevin86: Oops, white runs headlong into a back row mate.
Jul-23-14  dfcx: 33...black to move
The white rook on e4 is overloaded.
33...Qa4+ wins at least two rooks.

A) 34. Rxa4 Rxa4+ 35 Kb1 Rh8+

and mates soon.

B) 34. Kb1 Rh1+ 35. Qe1 Qxe4!


click for larger view

36. Rg1 Qxe1+ 37. Rxe1 Rxe1+ and wins two rooks

Jul-23-14  perhaps: can anyone tell me how it would be 32 Re8+ and black either looses the queen and soon the horse or get mated in 2 moves if the King moves to a7. Or am I missing something? Thanks

  Cheapo by the Dozen: <perhaps>,

There's no mate, because Black's knight can interpose at d4.

Jul-23-14  Maatalkko: Was this played in a tournament? If so, did this make Polgar the youngest player to defeat a GM at that time?
Jul-23-14  perhaps: Thanks "Cheapo by the Dozen", now you know that I am just getting close to be a beginner!
Jul-23-14  BOSTER: Jonathan : <Stared at it for ever so long and thought >. If only I could shift the knight at the beginning of the game after 13.Be3, 14.f3, 15.Na4 16.Nb6.
Jul-23-14  BOSTER: White should play 31.Nb1 and then Nc3-Na4-Nb6 , and any strategy says this.
Jul-23-14  TheBish: J D Tisdall vs Judit Polgar, 1988

Black to play (33...?) "Medium/Easy"

Black wins with the x-ray attack 33...Qa4+!, which either mates or wins major material.

A. 34. Rxa4 Rxa4+ 35. Kb1 Rh1+ and mate in a couple.

B. 34. Kb1 Rh1+ 35. Qe1 Qxe4 and now if 36. Rg1 Rxg1 37. Qxg1 Rh1 wins the house.
