  perfidious: Had never heard of Giri's opponent before seeing this POTD, but he too went on to become quite a competent player.

  agb2002: Black is one pawn down.

Black can take advantage of the semi-open g-file with 15... Rxg7:

A) 16.Bxb6 Bxg2#.

B) 16.Qxe2 Rxg2 17.Qe4 Qc7 (17... Rg1+ 18.Rxg1 Bxe4+ 19.Nxe4 wins for White -19... Qc6 20.Rg8#-)

B.1) 18.Qxg2 Bxg2+ 19.Kxg2 Qxc5 wins decisive material.

B.2) 18.Kxg2 Bxe4+ 19.Nxe4 Qc6 20.Rad1 f5 wins decisive material.

B.3) 18.Bd6 Bxe4 19.Bxc7 Bc6

B.3.a) 20.h4 Rxc2+ 21.Kg1 Rg2+ 22.Kh1 Rxb2+ 23.Kg1 Rg2+ 24.Kh1 Rc2+ 25.Kg1 Rc3 wins decisive material.

B.3.b) 20.Rae1 Rg6+ 21.Ne4 f5 wins a pawn at least.

C) 16.Nxe2 Rxg2

C.1) 17.Bxb6 Rg3+ and mate in two.

C.2) 17.Ng3 Rxg3+ wins.

C.3) 17.Rf3 Bxf3 18.Bxb6 Rg3#.

Jun-29-20  Rumor: How is this “very easy”? Ok, I had 15...Rxg7, ahead of 15...Nxc3 or 15...Qxc5, which turns out to be correct. But after 16. Ne4 Bxe4 17. Qxe2 Qb7 18. Rf2 Rc8, et seq, this isn’t exactly a two-move Monday puzzle, is it?
Jun-29-20  Brenin: White could have saved himself with 16 Ne4 Bxe4 17 Qxe2, so 17 ... Rxg2 is answered with 18 Qxe4. Instead Black has to play 17 ... Qc6 or Qb7, and then 18 Rf2 or Rg1 allows White to survive, though 18 ... Rc8 is going to cause problems.
Jun-29-20  saturn2: Well, black wins a pawn. In those lines with f4 it is good to play Kh1 first.
Jun-29-20  zb2cr: 15. ... Rxg7 works. Black is threatening ... Bxg2#.

White's most easily visible defense, 16. Qxe2, Rxg2; 17. Qe4, is refuted by 17. ... Qc7!. After 18. Kxg2, Bze4+; 19. Nxe4, qc6; 20. Rae1, f5 wins the Knight and Blakc has a good material edge.

<abg2002> has done excellent work with the other lines.

Jun-29-20  Ratt Boy: <Rumor: How is this “very easy”?>

I agree. Because it's a Monday, I kept looking for something simpler than 15…Rxg7.

That's okay; it's not a bad puzzle. It's just that the bigger puzzle, is why it was posted on a Monday. I'm figuring it belongs on a Windmill Wednesday.

Then as you suggest 17 … Qb7 18 Rf2 Rc8 causes problems


click for larger view

White's problems seem insurmountable. At this moment they are:

1) His bishop is pinned against c2

2) He will lose his g-pawn

3) Black threatens … Rxc5 and if the bishop is supported, … d6

The only way out is to attack the e4 bishop, when Black can't support it with … f5 because of Qh5+.

19 Re1 Bxg2+ 20 Rxg2 Rxc5 21 c3 Rc4


click for larger view

Black is a pawn up, and in the coming single rook endgame can tie White down to the weak f-pawn (which can't move now!), then play:

... f5, ... d6, ... e5 and ... e4 (unless White trades his f-pawn) to get a passed pawn in the center.

... a5 and … b4 to make his d-pawn a passed pawn as well. This gives White his own passed b-pawn, but it's no match for the two central passed pawns.

I don't see White surviving the two central passed pawns. Am I missing something?

Jun-29-20  Brenin: Thanks, <Predrag3141>, 17 ... Qb7 18 Rf2 Rc8 causes White serious problems indeed. Perhaps the best practical solution to them is 19 b4 d6 20 Bxd6 Rxc2 21 Qxc2 Bxc2 22 Rxc2, with R+B for the Q. The point I wanted to make was that this problem is far from a typical Monday open goal.
Jun-29-20  et1: very easy ? ohhhh NO

  chrisowen: Eh gotcha it is no? G7!
Jun-29-20  awfulhangover: Either this isn´t very easy, or I´m very dumb.
Jun-29-20  TheaN: In all honesty <17....Rxg7> is the obvious move because Black levels material and nothing's threatened on account of 18.Qxb6?? Bxg2# and 18.Qxe2? Rxg2 -+ starting a deadly windmill as in the game.

The biggest issue I had with 18.Rg1. One of White's worst in hindsight but it forces a shift in play. It defuses all of Black's current threats and Black will have to force 18....Ng3+! 19.hxg3 Qxc5 -+ as the open h-file turns out to be deadly for White: White is forced to immediately play 20.Nd5 as otherwise 20....Rg6 and disaster due to the RPP block for the White king. g2 can't move and the rook moving is pointless as the queen's aiming at g1.

That said, I didn't consider 18.Ne4 which of course allows White to aim at e4 after 18....Bxe4 19.Qxe2, so 19.....Rxg2? 20.Qxe4 +-. Instead, Black will have to settle for 19....Qb7 ∓, but it's not done yet.

Monday, though? CG I think you were thinking a bit too much of Qxb6?? or Qxe2? The rest isn't Monday level, this would have been a good Wednesday, and the correct mindset from the get go.

  gawain: Nice combination for Black to simplify while gaining some advantage--but for a Monday puzzle it seems rather inconclusive.

  Predrag3141: <chrisowen> That might be the first thing you said that I at least somewhat agree with.

  chrisowen: Testing ok um and no?
Jun-29-20  Cheapo by the Dozen: I struggled too.
Jun-29-20  devere: More of a Wednesday or Thursday than a Monday problem.
Jun-29-20  linlaoda: My line for 16. Ne4:

16...Bxe4 17. Qxe2 Qb7 18. Rf2 0-0-0! (this looks to be a unique idea compared to what has been previously suggested) with the idea of R8g8 and I don't see a defense to ...h5 It's worth noting that in this line Black can play ...f5 since there's no Qh5+

Jun-29-20  linlaoda: continuing my line above:

if 19. Kg1 then 19...Bxg2!-+
If 19. Rg1 Rdg8 20. h3 Rg3 21. Kg2 then something like 21....Qd5 with the idea ...Qf5 (which prepares Bxg2 then Qxh3
