  FSR: I'm very confused. Stockfish says of 15...Bf3 <better is 15...Bxg2 16.f3 Bxf1 17.Kxf1 Qh1+ 18.Kf2 Qh2+ 19.Ke1 = 0.00 (25 ply)>. Why is that better? Doesn't Miles' 15...Bf3 win instead of equalizing?

  LittleKibitzer: Strategy: In this variation l, black playing d5 is perhaps looking for f5 later. Here, it's more of a Stonewall setup than the usual pawn sacrifice on f5. It's interesting to see the diversity of ways of getting in f5, the defining tabia of this opening. How fantastic that black can exchange the d pawn and liberate the bishop on b7.
Jun-23-23  Mayankk: I thought the answer was

13 ... Bxh2+ 14 Kxh2 Qh4+ 15 Kg1 Bxg2 16 Kxg2 Qg4+ 17 Kh2/Kh1 Rf6 with 18 ... Rh6# to follow.

Of course in my simplistic world, White is obliged to accept the twin Bishop sacs even if he knows mate is coming.

Jun-23-23  geeker: Pattern recognition says it *has* to be a variant of the Lasker-Bauer double Bishop sacrifice. But 15...Bf3! is a subtlety I missed. Surprising that Dizzy got such a horrible position with White in the Queen's Indian after only 14 moves.

  coachjay: I use this position to reinforce the idea of pattern recognition at the end of my lesson on 1.The Greek Gift, 2.Lasker's Double-Bishop Sac, and 3.Alekhine's Block in my Green Belt Lesson Book (aimed at scholastic players, but chess is chess!). While I don't expect them to find the solution, I hope that they can learn the value of pattern recognition combined with calculation. Love it!
Jun-23-23  stacase: Did I get it move for move? No, but it darn near played itself.
Jun-23-23  raymondhow: No solve for me. I went for the double Bishop sac 14...Bxg2 before bringing the Queen out, which only works if White takes the second Bishop.
Jun-23-23  jrredfield: I quickly saw 13 ... Bxh2 14 Kxh2 Qh4+ 15 Kg1 and then guessed 15 ... f4 but then decided that 15 ... Bf3 was more assertive. (16 gxf3 Qg5+ 17 Kh2 Rf6 18 Bxf5 exf5 19 Qxf5 Qxf5 20 Ne5 Nxe5 21 Rh1 Qg5 22 dxe5 Rh6+#), 16 Qe2 (needed to prevent 16 ... Qg4 and mate in a few moves for Black) Bxe2 17 Bxe2 Rf6 and that's as far as I got. White is not all that far behind at this point, so I didn't see a definitive way for Black to finish the job.
Jun-23-23  jrredfield: I think the game turned against White after 13 Nxc4. 13 Be2 would have kept White close.
Jun-23-23  mel gibson: I knew it was one of the Bishops to take a pawn on either g2 or h2. I didn't know which one so I can't claim a solve.

Stockfish 15 says:
13... Bxh2+

(13. .. Bxh2+ (Bd6xh2+ Kg1xh2 Qd8-h4+ Kh2-g1 Bb7-f3 Qc2-e2 Bf3xe2 Bd3xe2 Nd7-f6 g2-g3 Qh4-h3 d4-d5 e6xd5 Nc4-e5 Ra8-d8 Be2-f3 Nf6-e4 Rf1-e1 Rf8-f6 Bf3-g2 Qh3-h5 b3-b4 c7-c5 a2-a4 Qh5-e8 ) +6.89/41 303)

score for Black +6.89 depth 41.

What if Black tried to take the g2 pawn with his White square Bishop?

13... Bxg2

(13. .. Bxg2 14. Kxg2 (Kg1xg2 Nd7-f6 Nc4xd6 c7xd6 d4-d5 Nf6xd5 Bd3-c4 Ra8-c8 Qc2-d2 Rc8-c5 Bb2-d4 Qd8-a8 f2-f3 Rc5-c7 Kg2-h1 Rf8-f7 a2-a4 h7-h6 Rf1-g1 g7-g5 Qd2-g2 Qa8-d8 Qg2-e2 Kg8-) +6.51/35 58)

score for White +6.51 depth 35 -
so it's a bad move!

Jun-23-23  agb2002: White is about to play Nxd6.

The position reminds me of the very famous games Lasker-Bauer (1889) and Nimzowitsch-Tarrasch (1914). This invites to play 13... Bxh2+:

A) 14.Kxh2 Qh4+ 15.Kg1 Bf3 (15... Bxg2 16.f3 and White seems to hold because the queen is protecting the second rank; not 16.Kxg2 Qg4+ 17.Kh1 [17.Kh2 Rf6 and mate soon] 17... Qf3+ [17... Rf6 18.f3 Rh6+ 19.Qh2], followed by Rf6, wins)

A.1) 16.gxf3 Qg5+ followed by 17... Rf6 wins.

A.2) 16.Rfe1 Rf6 17.gxf3 (due to Rh6 and Qh1#) 17... Qh3 wins.

A.3) 16.Ne5 Nxe5 17.dxe5 Qg4 18.g3 Qh3 and mate next.

A.4) 16.Nd2 Bxg2 (the knight blocks the queen now)

A.4.a) 17.Kxg2 Qg4+ as in the subline of A.

A.4.b) 17.f3 Bh3 (17... Qg3 18.Ne4 fxe4 19.Qxg2) 18.Nc4 Rf6 must be winning. For example, 19.Qh2 Rg6+ 20.Kh1 Bg2+ 21.Kg1 Bxf3+. Or 19.Rf2 Rg6+ 20.Rg2 (else 20... Bg2+ 21.Kg1 Qh1#) 20... Rxg2+ wins decisive material.

B) 14.Kh1 Qh4 15.Rfe1 Bg3+ 16.Kg1 Qh2+ 17.Kf1 Qxg2+ 18.Ke1 Qxf2#.

Jun-23-23  Brenin: My choice, after a very quick look (interrupting a mathematice conference) was 13 ... Bxh2+ (what else for a POTD?) 14 Kxh2 Qh4+ 15 Kg1 Bxg2, but this seems to be worth only a draw after 16 f3. I completely missed 15 ... Bf3.

  scormus: I'll take some solace at being in good company, as I overlooked 16 f3! after choosing the continuation 15 ... Bxg2, anticipating 16 Kxg2 Qg4+ with unavoidable mate in a few moves.

I suppose I should have realised I wouldn't get a Friday POTD quite that easily. Sigh :

  Check It Out: I'm going with old double bishop sac, queen check, and rook lift.

  Honza Cervenka: Double Bishop sac pattern was apparent but it was necessary to find a subtlety in 15...Bf3!! I missed that but frankly speaking I was not trying very hard to calculate all lines.
Jun-23-23  King.Arthur.Brazil: The first try was: 13...Bxg2 14. Kxg2 Qg5+ 15. Kh1 Qh4 16. Nxd6 cxd6, Black attack seems hopeless. Other move: 13...Bxh2+ 14. Kxh2 Qg5 15. e4 Rf6 16. g3 Rh6+ 17. Kg2 f4 18. Bc1 Rf8 19. Rg1 (Rh2+ 20. Kxh2 Qh5+ 21. Kg2 f3+ 22. Kf1 Qh3+ 23. Ke1 Qh2 24. Rf1...) Rh4 20. Kf1.

Then, we must go agressively with: 13...Bxh2+ 14. Kxh2 Qh4+ 15. Kg1 Bxg2 16. Kxg2 Qg4+ 17. Kh2 Rf6 and mate next. Therefore, White must refuse the 2nd ♗: 16. f3 Rf6 17. Qxg2 Rg6 18. Rd2 Rxg2+ 19. Rxg2 Rf8 20. Bc1... Maybe, it is preferable 16... Bxf1 17. Rxf1 Rf6 18. Rf2 Raf8...

Jun-24-23  Rosbach: Bf3 is amazing. Forcing white to block the Queen with the knight

  Honza Cervenka: 11.Rad1 was a mistake. 11.cxd5 is correct.
Jun-25-23  cocker: The position after 11 Rad1 was reached in a recent game, Dieu v Tari, Reykjavik, 2023. Tari didn't do as well as Miles. (Courtesy of David Howell's column in Sunday Times.)
