Dec-25-14  TheBish: P Horvath vs T Stoll, 2004

White to play (29.?) "Medium"

Not only is Black's king exposed, but his kingside defenders are greatly outnumbered by White's attacking army. It's as if White were ahead a queen, rook and a bishop -- since those pieces of Black's on the queenside are helpless onlookers while White concludes his attack.

29. Rh5+!

This is the key, as 29. Ng8+ Kg7 leaves White with a useless discovered check -- that's how well-hidden Black's pieces are on the queenside! The rook sac rips open Black's king position, and opens the long diagonal for the White queen.


Or 29...Kg7 30. Ng4+ Kg8 31. Nh6#.

30. Ng8+ Kg5 31. Qe5+ Kh4

If 31...Rf5 32. Qg3# is curtains for Black, as is 31...Bf5 32. Qg3+ Bg4 33. h4#.

32. Nf6 Rxf6 33. Qxf6+ Kg3 34. Qf3+ Kh4 35. g3+ Kxh3 (35...Kg5 36. Qf4#) 36. Bf1#.

Stoll's king takes a stroll!

Dec-25-14  sfm: <TheFocus: I like 29.Ng4+ Kg7 30.Re7+ Qd4 31.Qxgd4+ Kg8 32.Nh6 mate> Indeed likeable, but there is also 29.-,BxN
Dec-25-14  TheFocus: Uh oh. Forgot about that Bc8.

I'm getting too old for this.

Dec-25-14  TheBish: <TheFocus:> 29. Ng4+ is answered by 29...Bxg4.
Dec-25-14  TheFocus: Note to self: enroll in Tactics 101.
Dec-25-14  TheFocus: What about 29.Rh5+ gxh5 30.Qd2+ Kg7 31.Qg5+ Ng6 32.Nxh5+ Kg8 33.Re8+ Rf8 34.Qd5+ Kh8 35.Qf7.

  agb2002: White is one pawn down.

Black threatens 29... Rxf6.

White can create a mate attack with 29.Rh5+:

A) 29... gxh5 30.Qd2+ Kg7 31.Qg5+ Ng6 (31... Kh8 32.Qg8#) 32.Nxh5+

A.1) 32... Kf8 33.Qd8#.

A.2) 32... Kg8 33.Re8 Rf8 34.Qf6 with the double threat 35.Q(R)xf8# and 35.Qg7#. Longer is 34.Rxf8+ Kxf8 35.Qf6+ Ke8 (35... Kg8 36.Qg7#) 36.Ng7+ Kd7 37.Bf5+ Kc7 38.Ne8#.

A.3) 32... Kh8 33.Re8+ N(R)f8 34.Rxf8+ R(N)xf8 35.Qg7#.

B) 29... Kg7 30.Nd5+ Kg8 (30... Rf6 31.Qxf6+ Kg8 32.Ne7#) 31.Ne7+ Rxe7 32.Rxe7 Ne6 (32... gxh5 33.Qg7#) 33.Qf6 and mate in three.

Dec-25-14  morfishine: First, <29.Rh5+>

<29...gxh5> (not forced, but 29...Kg7 ends in a familiar pattern mate after 30.Ng4+ Kg8 31.Nh6#)

30.Ng8+ Kg5 31.Qe5+ Bf5 (or 31...Rf5 32.Qg3#)

32.Bxf5 Rxf5 33.Qg3#

  Once: Now, that is very clever. has give us a Christmas gift. Fritzie reckons that just about any sensible starting move wins. The top 16 moves all give overwhelming advantage to white.

Even 29.Ng4 Bxg4 evals at more than +7.8 - and it's not in the top 16.

Happy Christmas everyone!

Dec-25-14  morfishine: <Once> Highly interesting observation, especially 29.Ng4; Exquisite game by White aided somewhat by Black's surrendering of tempos here and there; for example: 7...Bg7? is not necessary, though it fits with Black wanting to develop his Knight to <f6>

  Sally Simpson: Merry Christmas Everyone.

Good, easy enough. (only hard bit was finally dismissing the dis-check with Ng8+ did not work.) So throw in the Rook check first, the Black King is pulled into the open and surley gets mated.

So where is the Christmas conection?

Well Peter and Thomas were two of the disciples. (I 'doubt' if that is it.)

After 11.Qd2 a mini Christmas tree appears.

OK....back to work.

Today, everyone's a winner. 29. Ne8 Qf2 30. Qc1+ Qf4 31. R1e3 Bd7 32. R5e4

Black has to throw his queen to avoid mate. Fritzie is slapping his lederhosen and yodelling something about +7.99

  scormus: Merry Christmas everyone.
Thanks <CG> for the present - and <Once> for confirming the generosity of today's POTD.

Had difficulty choosing, my emotions went with Ng8+ or Rh5+, though I confess not seeing a final mate. My head preferred Re7. I would like to think they all make <the <One Time> top 16 ;)>

The only plausible move I can see that doesn't advance W much is Qd2+

Dec-25-14  patzer2: My guess was 29. Rh5+ gxh5 30. Ng4+ Kg5 31. Qd7+!, which Fritz 12 indicates is mate-in-eight for this Thursday puzzle.

Neat Christmas present from, as Fritz indicates there are at least 20 winning moves for this (29. ?) puzzle.

Dec-25-14  morfishine: <patzer2> Wow, 20 winning moves! Forgive me if I decline looking at alternatives to 29.Rh5+: I had my first eggnog at 730am this morning...

Oh, nice avatar!

  thegoodanarchist: For fans of "Saving Private Ryan" just think: SERGEANT HORVATH!
Dec-25-14  varishnakov: [29.R-R5+ PxR (29...K-N2 30.RxP mate) 30.N-N8+ K-N4

31.Q-Q2+ K-R5 32.K-R2 with P-N3 mate to follow

Not the most exact in terms of mate in x, but it wins easily and in move black could have placed some pieces in the way to prolong, but nothing much.

Dec-25-14  Edeltalent: 29.? White to move

White's pieces are so dominant and Black's so badly placed and uncoordinated, that it's hard to believe White only had to give up one measly pawn to get this position. It's not that obvious how to finish Black off, but with heavy pieces on the board, the black king already in the open and not many defenders near him, a mating attack should be feasible. 29.Ng8+ or 29.Qd2+ Kg7 don't accomplish much, as the black king will feel a bit safer on g7 than on h6, so it would be better not to let him back easily.

Another very forcing move is 29.Rh5+, as after 29...Kg7 30.Ng4+ Kg8, the black king is not enjoying his arrival back home very much: 31.Nh6# delivers mate. So there's no choice but 29...gxh5. The g-file is open now, thus one try is 30.Qd2+ Kg7 31.Qg5+ Ng6 32.Nxh7, but after 32...Qb6 it doesn't look too convincing.

But apart from the g-line, also the long diagonal has opened, and as the white queen is doing a perfect job controlling it, 30.Ng8+ now drags the king further out. After 30...Kg5, the white queen can start to harrass the king from a closer distance: 31.Qd2+ Kh4 32.Re4+ Bg4 33.g3+ Kxg3 (Kxh3 34.Qh2#) 34.Qg2+ Kh4 35.Rxg4+ and mate, or 31.Qd2+ Rf4 32.Re5+ Bf5 (or Kh4 33.Qxf4+ Bg4 34.hxg4) 33.Rxf5+ Kg6 34.Qxf4 with mate to follow very shortly.

Dec-25-14  Mojodomo: Beautiful final position to unwrap today-- Merry Christmas everyone!
Dec-25-14  PJs Studio: After looking at 29.Ng8+ and seeing it doesn't work out the way I want it to, I instantly found Rh5+ without even seeing if the followup was a later Re5+ or Qe5+

OTB, I probably would have obtained a headache finding it.

Merry Christmas from upstate NY

Dec-25-14  morfishine: Yes, everyone's a winner; even if Black tries <28...Qc7> instead of 28...Qa7, the combination still works

29.Rh5+ gxh5 30.Ng8+ Kg5 31.Re5+ Kf4 32.Re4+ Kg5 33.Qd2+ Rf4 34.g3 Ng6 35.gxf4+ Nxf4 36.Qe3 Bxh3 37.Re5+ Kh4 38.Qf2+ Kg4 39.Bf5+ Kg5 40.Qg3+ Bg4 41.Bxg4+Qxe5 42.Bh3#


Dec-25-14  M.Hassan: "Medium"
White to play 29?
White is a pawn down

29.Rh5+ gxh5
30.Ng8+ Kg5
King is out of his hiding place:

31.Qe5+ Rf5
Merry Christmast to all Christian players.
