in both my and <YouRang> forum before the games start. Thanks.

Sep-30-11  ounos: Found it in around half a minute - but there was nothing else there to make this trickier (OTB it would be tricky alright though)

  dzechiel: White to move (30?). Material even. "Difficult."

The white knight is in jeopardy. At first I wanted to move it to f3 with the idea of posting it on g5, but while that's a nice outpost for the knight, it isn't exactly winning. Still, the knight problem must be attended to.

It looks like white can snag a couple of pawns with a combination starting...

30 Nxg6

With the threat 31 Ne5+ followed by 32 Nxd7.

30...Qxg6 31 Qxg6+ Kxg6 32 g4

attacking the rook, and threatening 33 Bxf5+ and 34 Bxd7. Where to move the rook? There really aren't any good squares. On

32...Rh2+ 33 Kg3

now the black rook is en prise, and white still threatens 34 Bxf5+ etc.

33...Rh7

Perhaps black can protect the knight.

34 Bxf5+

Skewing the king and rook. The king must protect the rook, but there's no good square.

34...Kg7

The alternative, 34...Kh6 is much worse after 35 Rh1+ and 36 Rxh7.

35 Bxd7

and the black king prevents the rook from recapturing on d7. The white f- and g-pawns should spell the difference.

Time to check.

Sep-30-11  ounos: Sigh. If the puzzle was given one move earlier, it would be really, really useful as an exercise, it would be *much* less "puzzle like", exactly the kind of puzzle I would wish to be seeing here.

  Phony Benoni: My first thought was, "Wait a minute! This isn't Spielmann vs B Hoenlinger, 1929!" Different game, of course.

<30.?>

Looks like possible kingside destruction. Two captures on f5 are just B+N for R+P; hopefully something better. 30.Nxg6 doesn't lead to anything. Can we lure the rook off h5?

Black has pieces hanging on b7/d7, but how do we get to them? 30.b4 hardly seems forcing.

Well, if we capture twice on g6 we can lure the king into a pin and play g4. That will give us two pawns for the piece, but hardly a steamroller. Hold on! Loose Pieces Drop Off!

<30.Qxg6+ Qxg6 31.Nxg6 Kxg6 32.g4>. Double attack on Rg5 and pinned Pf5, and double attack with check threatened by 33.Bxf5+. The rook can't guard f5, and 32...Rh2+ is answered by 33.Kg3, when it looks like everything is still on and Black has no further checks.

A lesson in putting together the various tactical factors.

Sep-30-11  CHESSTTCAMPS: I started looking at a sac on f5, but it quickly became apparent that a sac on g6 would win material, e.g. 30.Nxg6! Qxg6 31.Qxg6+ Kxg6 32.g4! Rh2+ (Rh7? 33.Bxf5+ Kg7 34.Bxd7) 34.Kg3 Re2 35.Kf3! Rb2 35.Bxf5+ K moves 36.Bxd7 (the point) Rxa2 37.Rxc5. White has picked up two pawns and they are connected passed pawns on the kingside - a clearly won endgame. Time for a quick review...
Sep-30-11  tacticalmonster: 30 Qxg6+ Qxg6 31 Nxg6 Kxg6 32 g4 Rh2+ 33 Kg3 Rxa2 34 Bxf5+ Kf6 35 Bxd7

time spent: 2 min

Sep-30-11  CHESSTTCAMPS: Oddly enough, before looking at today's POTD I was playing a tricky bishop and rook ending resulting from the POTD on Tuesday. The Tuesday puzzle leads to an ending I found very difficult to play against an engine. I may add a related post to that forum later.

  al wazir: The pinned P after 31...Kxg6 was easy to spot; what was harder was to see the winback of the N on d7. However, I didn't foresee that black would blunder away a piece on move 39. If that was part of the plan, I missed it.
Sep-30-11  JohnBoy: <tacticalmonster> - 33...Rxa2 in your line is a blunder. 34.gf5+ and 35.Bxa2 do the job. I saw your line at first. For me the error seems to come from looking at a diagram and not a board.
Sep-30-11  TeaChess: 30. Qxg6+

Nxg6 is not good enough, since black can play Qb2+ to complicate the situation.

Sep-30-11  APatzer: Is Rh1 - Rh3 a good move ? Or a losing move ?

Ok, in the puzzle position above, black has two threats. He is double attacking the h knight and also has the sneaky 30...Qb2+, which wins the bishop.

This means that 30 Nxg6 is no good because of 30...Qb2+.

<Phony Benoni> seems to have put it all together with his <30.Qxg6+ Qxg6 31.Nxg6 Kxg6 32.g4 and 32...Rh2+ is answered by 33.Kg3> line.

Black would have been better off if he had subsequently played 33...Re2, instead, it appears.

Sep-30-11  rilkefan: Black is about to win the h4 knight or play Qb2+ picking up something on the qside. I looked at 30.Bxf5 and 30.Nxf5, with the idea that the bishop on f5 hold c2 in the Qb2+ line and hits the d7 knight - but when I noticed that g4 would fork the rook and f5 (and add pressure on the b1-h7 diagonal) I decided on Qxg6, which seems to win a pawn at least and leaves the f4/g4 pawns to run, which I imagine is enough to win (esp. given same-colored bishops) for someone good at endgames.

  FSR: 30.Nxg6! looks surprisingly strong. If Black doesn't take, he's just lost a key pawn for nothing. On 30...Qxg6, 31.Qxg6+ Kxg6 32.g4! is very strong. Then White threatens the rook, and if it moves away (say 32...Rh8), White regains his piece with interest with 33.Bxf5+ K moves 34.Bxd7. Black has no good response: 32...Rh2+ is met simply by 33.Kg1, while 32...Rh7 (trying to guard the knight) fails to 33.Bxf5+ Kh6? (33...Kg7 34.Bxd7) 34.Rh2+ and wins.

  FSR: Spielmann was pretty bald in his later years, but his opponent was Baldur.

  FSR: Woops! JimfromProvidence is right that 30.Nxg6? Qb2+! is most unpleasant, so White must play the immediate 30.Qxg6+!
Sep-30-11  tonlliwi: It looks like 30. Qxg6 Qxg6 31. Nxg6 and if Kxg6 then white has g4 pinning the f pawn and attacking rook. Rook needs to come up to h7 to defend the knight after Bxf5+. So then Bxf5+, k to h6 (g7 blocks rook). White now has two options, take the rook ending up with rook and 2 extra (strong) pawns vs bishop and knight or take the knight and be three pawns up vs rook and bishop. I would probably take the knight, that gets rid of black connected pawns, wins an extra pawn, and opens the c-file for my rook, and leaves black with two unconnected pawns. Looks very good for white. Best defense for black is probably decline the knight and bring the king to f6 instead.

  sevenseaman: Candidates galore;

1. Bxf5, 2. Nxf5 3. Qxg6

None of them seem to win for White, at least not in the short run. Have spent 10 minutes and am still as baffled as at the beginning.

30. Qxg6 appeals a little as it will give me a P during exchange of Qs. But a N will go for a P. It is never good business.

I just have to concede I am unable to match <Spielmann> even when I know its a puzzle.

A puzzle is considered solved if you have a candidate and can see the denouement most of the way. I do not, not today.

Admit defeat or in the 'never say die spirit' go some way on a wild shot?

Just venturing;

30. Qxg6 Qxg6 31. Nxg6 Kxg6 32. g4 Rh2+ 33. Kg3 Rd2 34. Bxf5+ Kf6 35. Bxd7>

Aah, equality, nay a P to the good! But Black will now develop a dangerous threat on g2 by pushing d4.

<35...d4 36. exd4 Rg2+ 37. Kh3> (Kh4 leads to a Black win and White is in trouble and needs to take care)

There are many items on the menu and I really do not fancy my chances.

It does not look good to me. Hope I've not messed up. There is too much to visualize and I drop the hot brick here;

Sep-30-11  tonlliwi: Oops! Kh6 fails to Rh1+. Didn't notice that at first. I guess Rh2 is the best reply then.

  rhickma4: White looks to have a surprising little combination available here.

30.Nxg6+ Qxg6 31.Qxg6+ Kxg6 32.g4
This threatens both the Rook and Bxf5+

32...Rh2+ 33.Kg3 Re2 34.Bxf5+ Kf6 35.Bxe7
White looks to end 2 pawns ahead with a winning endgame.

32...Rh7 33.Bxf5+ Kh6 34.Rh1+ is even worse for Black

IF Black does not take the N, then it can retreat to e5, winning a pawn

Not sure if this is the idea or not!
Maybe it better to play the moves in the other order: 30.Qxg6+ Qxg6 31.Nxg6

  sevenseaman: Today I received the shipment of <'art of attack in chess' by Vladimir Vukovic>. How is the general opinion on the utility of this book?
Sep-30-11  SimonWebbsTiger: @<sevenseaman>

<the Art of Attack in Chess> is a genuine classic. Enjoy!

If you haven't got it, add Jacob Aagaard's <Attacking Manual> (Vol 1+2) to your books. Jacob discusses some of the weaknesses in Vukovic's book; his books are also highly praised. (Peter Heine used some of the exercises in Jacob's book when training Anand prior to the Topalov match.)

Sep-30-11  gofer: Black is threatening Rxh4 and the less obvious Qb2+ winning a piece. The latter is very dangerous for black as it exposes it's king to Qxg6+, so probably wont be played immediately but the threat is always there!

For example, the simple <30 Rh1> unleashes hell from black as follows;

30 Rh1 Qb2+
31 Kf3 d4+
32 e4 fxe4+

33 Bxe4 Bxe4+
34 Kxe4 Qe2+
35 Qe3 Nf6# (not the dull Qxe3#!)

33 Kg4 Nf6+
34 Kh3 Bf1+
35 Kh2 Ng4+
36 Kh3 Ne3+
37 Kh2 Rxh4+!
38 Kg1 Rxh1+
39 Kxh1 Qxb1+
40 Kh2 Nf1+!!! Oh I hope black gets to play this!!!

So as white, We could try for exchange queens and avoid <30 ... Qb2+>

<30 Qxg6+ Qxg6>
<31 Nxg6 ...>


click for larger view

At this point I think black has to decline the sacrifice. Due to...

31 ... Kxg6
32 g4! ...

at which point losing either Nd7 or Re2 is unavoidable

32 ... Rh2+
33 Kg3 Re2
34 Kf3 Rh2
35 Bxf5+ Kf7
36 Bxd7 Rh3+
36 Ke2 ...

So at this point we have to look elsewhere.

<31 ... Kf6>

Okay our knight is now trapped! So we have to give back the pawn, perhaps

32 g4 fxg4 35 Kg3 Rh3+ 36 Kxg4 Rxe3 is this good for white?? probably not

<32 Ne5 Nxe5>
<33 fxe5+ Kxe5>
<34 Rxc5 Kd6>
<35 Ra5 a6>
<36 Bd3 ...>

Now this is not over by any means but it looks okay for white...

Time to check...

  morfishine: White can reduce to a winning endgame with a temporary piece sac: <30.Nxg6 Qxg6 31.Qxg6+ Kxg6 32.g4>

32.g4 simultaneously attacks Blacks rook and the pinned f-pawn, giving white time to recover the piece.

After <32...Rh2+ 33.Kg3 Rd2 34.Bxf5+ Kf6 35.Bxd7> White is up 2-pawns with a technically won position
