The clear losing move according to Fritz was 30. h4? which allows the winning shot 30...Rxg3!! Instead, White needed to try 30. c4 Rg6 putting up more resistance and avoiding immediate loss.

The obvious move is 30... Rxg3, weakening the dark squares around the white king:

A) 31.Rxg3 Bxf4

A.1) 32.Qe2 Qxh4+ 33.Nh3 (33.Kg2 Qxg3+ 34.Kf(h)1 Qxg1#) 33... Rxg3 34.Rxg3 Qxg3+ followed by 35... Qxh3+ - + [B+3P].

A.2) 32.Qe1 Qxh4+ 33.Nh3 (33.Kg2 Qxg3+ 34.Kf1 (34.Kh1 Qxh3#) 34... Qxh3+ 35.Ke2 (35.Kf2 Qf3#) 35... Qd3+ 36.Kf2 Qf3#) 33... e3 with the idea of promoting the e-pawn after trading the heavy pieces on g3. For example, 34.R1g2 e2 35.Rg1 (35.Qxe2 Rxg3 36.Rxg3 Qxg3+ 37.Kh1 Qxh3+ 38.Kg1 Be3+ wins) 35... Rxg3 36.Rxg3 Qxg3+ 37.Qxg3 Bxg3+ 38.Kxg3 e1=Q+ wins.

A.3) 32.Qxf4 Qxf4 33.Nh3 Qd6 - + [Q+2P vs R+N] (33... Qxh4 34.Rxg8#; 33... Qd2+ 34.R1g2 + -). For example, 34.Ng5 Rg7 35.Kh1 (threatening 36.Nf7+) 35... h6 wins the knight.

A.4) 32.Ng4 Rxg4 wins. For example, 33.R1g2 Qxh4+ 34.Kg1 Bxe3+, etc. Or 33.Qe1 Qxh4+ 34.Kg2 Rxg3+, etc.

Fireworks start with <30...Rxg3> forcing 31.Rxg3 Bxf4

The short fireworks display leaves White helpless:

(1) 32.Nh3 Rxg3 33.Qxg3 Bxg3+ 34.Rxg3 Qxh4
(2) 32.Qe2 Qxh4+ 33.Kg2 Qxg3+

Happy New Year to all at CG! They didn't let us off the hook with this Thursday puzzle, because this combination is a difficult one. As usual with a puzzle spotting the first move is usually not the problem, and because it has the stamp 'puzzle' the continuation is usually found. Otb, this would be tricky to calculate.

Though material is even, black has a stronger piece and a passed pawn, though this pawn of part of a doubled pawn. The g-file is currently in semi-control by black, and it quickly becomes clear g3 is white's weak spot keeping both the black bishop and queen at bay. The breaks sideways don't work (30....Qxh4+? 31.gxh4 makes no sense and 30....Bxf4? 31.Qxf4 only consolidates white's position), so we go right through the middle: <30....Rxg3!>.

Declining this sac is not even a reasonable alternative. <31.Rxg3 Bxf4 32.Qe1> mind that after <32.Qe2?<>> white surrenders a defender of g3 <32....Rxg3! 33.Rxg3 Qxh4+ 34.Kg2 (Nh3? Qxg3+ 35.Kh1 Qxh3+ ) Qxg3+<>> black already won the rook back <35.Kf1 (Kh1 Qh2#) e3! <>> and the position soon collapses. <32....Qxh4+ 33.Nh3 (Kg2 Qxg3+ )>.

30... Rxg3! removing the lynchpin that defends against both the B&Q lines of attack. The threat is 31...Qxh4+ forcing mate.

A) 31.Qxg3 Bxf4 32.Kh3 Bxg3 33.Rxg3 Rxg3 34.Rxg3 f5 prevents counter-play Ng4 and black's pawns will decide.

B) 31.Rxg3 Bxf4 32.Qe1 Qxh4+ 33.Nh3 e3!

Now white's predicament is clear: Nh3 and Rg3 can't move because they are pinned, while K and Q can't move because Rg3 will not have enough defenders. Not quite a zugzwang, but a lethal squeeze.

34.R1g2 e2! (Black can force the issue) 35.Qxe2 Rxg3 36.Rxg3 Qxg3+ 37.Kh1 Qxh3+ wins.

B.1 32.Qxf4 Qxf4 33.Nh3 Qc7 34.Ng5 h6! 35.Nxf7+ Qxf7 36.Rxg8+ Qxg8 37.Rxg8+ Kxg8 leaves a simple K&P ending.

B.1.1 35.Nh3 Rxg3 36.Rxg3 f5 and black's pawns will prevail.

B.2 35.R1g2 Rxg3 36.Rxg3 Qxg3+ 37.Bxg3+ followed by 38.e1=Q wins

Happy New Year and Happy Solving!

a) seems to be using a simple computer algorithm to post jumbles of gibberish, of which perhaps 9% is identifiable as chess-related terminology, with the rest being nonsense;

b) does so in a very long-winded, repetitive, and disruptive manner.

It's one thing to call a true genius a genius. For instance, the novelist Mark Z. Danielewski really DOES write brilliant gibberish in his book *House of Leaves*. Danielewski really IS a genius--but chrisowen? Not so much.

So then what is he? He's routinely posting massive batches of senseless gibberish in a chess forum--a fact which has no doubt prompted many users to put him on ignore. This, to me, automatically marks Chris as a species of troll, who probably doesn't belong in the forum (he's not contributing anything coherent, let alone chess-related).

He's someone who wants attention, and he's willing to be long-winded, irrelevant, and disruptive in order to get that attention. (How many times have you been perusing the chess-related comments of a game with interest, only to come across one of Chris's gibberish posts and find your train of thought derailed? He's actually *distracting* people from chess: sort of the opposite of the site's purpose.)

I'm a big admirer of off-the-wall, zany stuff, and maybe the first few times Chris did this it was fun or interesting; but doesn't it seem like he's just feeding words into some online word-jumbler or translator and then pasting the results into these threads with a few "g7"s thrown in to make it tangentially relevant?

That's about as much of an "art form" as randomly dumping hundreds of gallons of paint onto a huge piece of paper and then expecting people to call you Jackson Pollack.
