Yeah, if that guy's a professional punster he should definitely consider a korea change.

Just wanted to prove that you can always sink lower. I propose a bad pun contest. Top, I mean bottom this!:

Oluto Adu about nothing

  Breunor: Stockfish doesn't like 18 ...e4:

1) +1.65 (22 ply) 19.Nxh6+ Bxh6 20.Bxh6 Kh7 21.Bc1 exd3 22.Qxd3 Nf6 23.Qxd8 Rexd8 24.Bg5 Kg7 25.Nd2 Rd7 26.Nf3 Rcd8 27.Bf1 Re7 28.Bb5 Bd5 29.Nd2 Rde8 30.Rxe7 Rxe7 31.h4

It likes g5 more:

1) +0.65 (20 ply) 19.Ngxe5 Nxe5 20.Nxe5 Bf5 21.f4 Re6 22.a5 bxa5 23.Qh5 Bg6 24.Qf3 gxf4 25.Qxd5 Qxd5 26.Bxd5 Rxe5 27.Rxe5 Bxe5 28.Bxf4 Bxf4 29.gxf4

White gives up the advantage with 20 Bxe4

1) -0.34 (23 ply) 20...Nf6 21.Bxc6 Rxc6 22.Ne5 Rc7 23.Qd2 Qd5 24.g4 Rce7 25.Qf4 Nxg4 26.Nhxg4 Bxg4 27.Qxg4 Rxe5 28.Rxe5 Rxe5 29.Bf4 Re8 30.Be3 Qxd3 31.Rd1 Qf5 32.Qxf5 gxf5 33.Re1 Kg6

Rather, 20 Rxe4! with the threat of Rh4 keeps white ahead:

1) +1.51 (20 ply) 20...Qd7 21.Qd2 Nf6 22.Rh4 Nh5 23.g4 Qd8 24.Rh3 Qd7 25.Nf5 gxf5 26.Rxh5+ Kg8 27.gxf5 Bxf5 28.Nd6 Qxd6 29.Rxf5 Ne5 30.d4 cxd4 31.Qxd4 Rcd8

It is even until move 24, f3 gives up the advantage:

1) -1.32 (21 ply) 24...Rce7 25.Qg5 Bh3 26.Qh4 Nh5 27.Qxh3 Rxe5 28.Rxe5 Rxe5 29.Ng4 Re1+ 30.Kf2 Qe6 31.Nf6+ Bxf6 32.Qxe6 Rxe6 33.a5 g5 34.axb6 axb6 35.Ra7 Kg6 36.Rd7 Be5 37.Be3 Rd6 38.Rxd6+ Bxd6 39.d4 Ng7

Stockfish recommends c4:

1) -0.11 (19 ply) 24.c4 Qb7 25.f3 Ng8 26.Nxg8 Kxg8 27.f4 Rce7 28.Qg2 Qxg2+ 29.Kxg2 Bf5 30.Bd2 Bxe5 31.fxe5 Bxd3 32.Bc3 Bxc4 33.Red1 Bb3 34.Rd6 Kg7 35.h4 Be6 36.Re1 Bb3

The final mistake is 26 cxd4:

1) -2.35 (22 ply) 26...Rxc1 27.Raxc1 Bxh6 28.f4 Ne4 29.Qe2 Qxd4+ 30.Qe3 Qxe3+ 31.Rxe3 Rxe5 32.Rce1 Ra5 33.Rxe4 Bf8 34.Kf2 Bf5 35.Rc4 Be6 36.Rxe6 fxe6 37.Re4 Rd5 38.Kf3 Rd2 39.Rxe6 Rxb2 40.Rc6 Kh6

Instead, Nxf7 keeps white in the fight (although still in some trouble):

1) -1.23 (23 ply) 26...Rxf7 27.Nxf7 Qxf7 28.Rxe8 Qxe8 29.Qf2 Nd5 30.Bd2 dxc3 31.bxc3 Nxc3 32.Re1 Qd8 33.Kh1 Bd4 34.Be3 Bf6 35.a5 Nd1 36.Qe2 Nxe3 37.Qxe3 bxa5 38.Qxa7+ Kh6 39.Qe3+ Bg5 40.Qe2 a4

  agb2002: Black has the bishop pair for a rook and two pawns.

White threatens Qxe4.

Black can open lines with 29... Rxe5 to attack the white king:

A) 30.fxe5 Nf2

A.1) 31.Kxf2 Qg2#.

A.2) 31.Qf1 Bxf1 32.Kxf1 (32.Kxf2 Qg2#; 32.Rxf1 Nh3#) 32... Qf3 (or 32... Nd3) wins.

B) 30.dxe5 Qxd3 wins.

  landshark: 29. -RxN does the trick: If 30.f4xR, Nf2 mates and if 30.d4xR, QxQ is sufficient if not quickly mating too. If W ignores the capture, he's too far behind in material plus his exposed K will prove quickly fatal.
Sep-05-18  Walter Glattke: White has a rook and two pawns for 2 bishops, 1 pawn untit ahead, Kim's move is very good, opens the diagonal h6-c1, threatens 30.fxe5 Nd2! 31.Qe2 Nf3+ 32.Kh1 Nxd4+ or the match with 30.-Nf2? whith black Advantage. 31.Kxf2 Qg2# or 31.Qf1 Bxf1 32.Kxf1. A normal club player only would play 29.-Nc5 30.Qe2 Nb3 31.Rcd1 Nxd4 32.Rxd4 Qd4+ 33.Qf2 with black advantage.
Sep-05-18  Mayankk: If the e4 knight magically disappears, Black has an easy mate-in-one on g2. However if we give White a tempo, it can block off the diagonal via Qf3, since it supported by the e5 knight.

So Black first chops off the e5 White knight. Luckily it also opens a diagonal for h3 Bishop (the puzzle has to have a solution, so some things automatically fall in place). It then moves the e4 Knight to f2, so that g2 is not accessible to either Queen or the Rook. And mate follows shortly thereafter.

  patzer2: Didn't remember 30...Nf2 -+ (mate-in-six, Stockfish 9 analysis of move 31.?) as the solution to the Monday, April 25, 2011 puzzle.

For today's Wednesday Sep 5, 2018 puzzle, I went with 29...Rxe5 30. fxe5 Nc5 -+ (-16.79 @ 19 ply, Stockfish 9) analysis of move 31.?) as my solution.

So where did the losing side go wrong? For one thing, White missed the near winning 20. Rxe4! Qd7 21. Bd2 Bxh6 22. Rh4 ± to +- (+1.69 @ 35 ply, Stockfish 9) which threatens 20. Rxe4! Bxh6? 21. Rh4 +- (+2.65 @ 26 ply, Stockfish 9).

Instead 20. Bxe4? Nf6 ∓ (-0.47 @ 34 ply, Stockfish 9) turned the game in Black's favor.

Sep-05-18  AlicesKnight: Found the game-line fairly quickly. Neat tactical points. Premature attack repelled. Bishops in concert. Attractive finish.
Sep-05-18  saturn2: 29..Nc5 should also work. The queen has to stay on the 2 rank.

30. Qd2 Nb3

If 30 Qc2 or 30 Qe2
30..Qxd4 decides.

Sep-05-18  saturn2: uh. white simply answers 29 dxN
Sep-05-18  dannydoc: White's move at 30 fxE5 is wrong, he should have moved Qc4.

Had you meant 30.dXN, is O.K because of 30...Qg2#

Sep-05-18  saturn2: thx <malt>
I had worked out 29..Nc5 carefully in the morning. When I posted it and the subsequent answer it was 1 hour later. For some reason I was unnecessarily shocked by 30 dxN when I gave ny post a 2nd glance. This even though I had hust written that rhe queen has to be at the 2nd rank...;)

I was waiting to see a sound bite for "Rocket Man" posted by <lost in space>

Sep-05-18  PJs Studio: I like this combination a lot! Black can whip up an attack many different ways in this position and the absolute quickest method is Rxe5! first. Very nice combo by South Korea’s only GM.
