Feb-19-18  Cheapo by the Dozen: Fish should be eaten with two forks.

  Once: Aw, ain't that cute? Two forks in a row.

  Dionysius1: I assume Jeran saw the tactic once Black played 18...♗xh3, which would be why he didn't play 19 hxg3. So he must have decided to be a good sport and play 20 ♔xg2 to let Cawdrey show his working. But 19 f4 would have been ok.
Feb-19-18  Cybe: Simply: 20. c:d4.
Feb-19-18  AlicesKnight: Use the forks, Luke, use the forks! After ...Qxh2+ 21.Kxh2 Black forks K and Q, and by capturing the Q forks the Rs.
Feb-19-18  gofer: <18 ... Bxh3> was a nice sacrifice!

White tries to refuse it, due to combination that was about to be played, but must have only seen part of it not the whole thing (which seems a little strange)...

<19 c3 ...>

But black just kept on ramming it home!

<19 ... Bxg2!>

The bishop still has to be ignored...

20 cxd4 Bxf1
21 Rxf1 cxd4 -+

The outcome of letting the bishop run rampant is that black has three pawns and an exchange up for the bishop. But its not over completely.

-1.01 (28 ply) 1.cxd4 Bxf1 2.Rxf1 cxd4 3.f4 c5 4.Kh1 Rac8 5.Nf3 f6 6.Rg1 Kf7 7.Kg2 Rg8 8.Kf1 h6 9.Qh2 h5 10.e5 Qd7 11.Ke2 Rb8 12.Qg3 Rbd8 13.a4 Rb8 14.axb5 Rxb5 15.Nd2

Instead we get the game continuation, where black is two pawns up and an exchange up with no loss of a piece...

-5.22 (30 ply) 1.Rh1 Kg7 2.f5 gxf5 3.exf5 Rd5 4.Kf4 Kh8 5.a4 Rg8 6.axb5 cxb5 7.c4 bxc4 8.bxc4 Rd4+ 9.Kf3 Rg5 10.Ra1 h5 11.Rxa7 Rxf5+ 12.Ke2 Re5+ 13.Kd2 h4 14.Ra1 h3 15.Rh1 Rh4 16.Nd1 h2 17.Nf2 Rg5 18.Ne4 Rg2+ 19.Ke3

White made the wrong choice on move 20...

Feb-19-18  gofer: As the "fork" puns are flowing liberally...

"White gets royally forked by 21 ... Nf3+"

  malt: 20...Q:h2+ 21.K:h2 Nf3+ 22.Kg2 N:d2
and a choice of rooks!
Feb-19-18  morfishine: 1,2,3: First, 20...Qxh2+ then, 21...Nf3+ and finally, 22...Nxd2 leaves Black up an exchange + two pawns

time to resign

*****

Feb-19-18  pth: <gofer> What about 19. f3 as a way of countering the sacrifice?
Feb-19-18  zb2cr: Black starts out here by being down a Knight for 2 Pawns. The sequence is easy to see:

20. ... Qxh2+; 21. Kxh2(forced), Nf3+; 22. Kg3, Nxd2. Now, Black has forked White's Rooks and will end the combination up by the exchange and 2 Pawns.

Feb-19-18  Hevelius: Forks, forklifts and pitchforks... good Monday to everyone.
Feb-19-18  Everyone: Oh yeah!!!

  patzer2: For today's Monday (20...?) puzzle solution, the sham Queen sacrifice 20...Qxh2+ -+ allows Black two consecutive knight forks to win back a piece, win the exchange and force White's resignation.

White's clearly decisive mistake was 20. Kxg2?, allowing 20...Qxh2+ -+ (-5.22 @ 32 ply, Stockfish 9). Instead, 20. cxd4 Bxf1 21. Rxf1 cxd4 22. f4 ∓ (-1.01 @ 28 ply, Stockfish 9 analysis of move 20.?) might have given White practical drawing chances.

A move earlier, instead of 19. c3? allowing 19...Bxg2! ∓ (-1.01 @ 28 ply, Stockfish 9), White could have held the game level with 19. f4! = (+0.06 @ 32 ply, Stockfish 9 analysis of move 19.?).

  mjmorri: It appears that White avoided 19.gxh3 to prevent the very combination that he allows one move later. Very strange.

  Breunor: Stockfish rates the game as even (0.06) after 18 Bx h3:

1) +0.06 (32 ply) 19.f4 Bc8 20.c3 Ne6 21.f5 gxf5 22.exf5 Ng7 23.Ng4 Nxf5 24.Rxf5 Bxf5 25.Nh6+ Kh8 26.Nxf5 e6 27.Nh6 Rd5 28.Qf2 f5 29.c4 Re5 30.d4 Re4 31.Nd3 Qg7 32.Nxc5 Qxh6 33.Nxe4 fxe4 34.Qe2 e3 35.cxb5 cxb5 36.Qxb5 Qg7 37.Qe5 Qxe5 38.dxe5 Rd8 39.Re1

I guess the key move here is 19 f4; after 19 f4, B x g2 is +1.83 for white.

Feb-19-18  BOSTER: How many players pointed out 19.f4
was nice. Other way we can't prove moves like 15.Nh2 and 18.Qd2.
Feb-19-18  drollere: that is forked up beyond all repair.
Feb-19-18  Olsonist: It’s a nice attack but what makes it so Monday is that there’s really no other move to look at.
Feb-19-18  BOSTER: <Olsonist: there's really no other move to look at>. At least you have to see the second
fork.
Feb-19-18  morfishine: fork me, fork you

  PawnSac: < morfishine: fork me, fork you >

white could have played 19.f4 guarding g2 and f3 with the Q and Nf3 would have been prevented, so white actually forked himself! (can you tell someone to go do that??) anyway, after 18...Bxh3 19.f4 Bd7 20.c3 (or f5 followed by c3) it would be white with the initiative and black's k side becomes exposed. So white really forked himself up good.

Feb-19-18  morfishine: <Pawnsac> How right you are, I would go ahead and retreat Black's LSB all the way to <c8> spying <a6> not that it would help much, but strategically it looks better

The point is that after 18...Bxh3 19.f4 Bc8 20.c3 Ne6 Black can retreat his Knight to <f8> providing security
