Sep-20-05		olaf4lena: 23. QxPd4 seems to be a critical error allowing Gruenfeld to pin the Queen against the king via the Bishop sacrifice on a3.

Mar-30-11		sfm: Tenacious defense. I have a lot of respect for people who fight. All the greatest were and are like that.

Jun-12-15		fredthebear: This is game #66 in "Masters of the Chessboard" by Richard Reti. It's one of the classic chess books that will instruct and inspire you.

Dec-18-16		TerryMills: Thank you to fredthebear; based on your suggestion I have just bought "Masters of the Chessboard"

Apr-10-22		Saniyat24: Wolf's bane...!

Jul-31-24		King.Arthur.Brazil: As called "easy", the king looked at powerful move: 25... Bf5 threatening Qc2#. For 26. Qd2 or Rd2 the reply Qa2 is enough.

Jul-31-24		mel gibson: I also chose the game ply. Stockfish 16.1 chooses a different ply: 25. .. Bf5 (25. .. Bf5 (1. ... Bf5 2.Rd2 Qa2 3.Kd1 Rxc3 4.bxc3 Qb1+ 5.Nc1 Be4 6.Rh3 Bxa3 7.Ke1 Bf5 8.Rg3 Qxc1+ 9.Rd1 Qc2 10.Qd2 Qe4 11.Qd5 Ne6 12.f4 Bf8 13.h5 a5 14.Qxe4 Bxe4 ) +5.51/43 113) score for Black +5.51 depth 43. if I force SF to choose the game ply it's the same strength: 25. .. Bxa3 26. bxa3 (26. bxa3 (1.bxa3 Qxa3+ 2.Kd2 Rd8 3.Rhg1 Rxd4+ 4.Bxd4 Bc4 5.Ke1 Ne6 6.Be3 Qa5 7.Rc1 b5 8.Rg4 Bxe2 9.Kxe2 b4 10.Nd1 Qb5+ 11.Ke1 a5 12.Nb2 Rd8 13.f3 b3 14.h5 Qe5 ) -5.60/40 232) score for White -5.60 depth 40.

Jul-31-24		Mayankk: Black has pinned the White c3 Knight and trying to corner the White King around it. Note that the d2 escape square is not really available due to Rd8 threat and capturing White Queen. The first motif which comes to mind is 25 .. Bxa3 26 bxa3 Qxa3+. Now White King has a few options, all of which lead to ruin. A) 27 Kd2 Rd8 and Queen is gone B) 27 Kc2 Bb3+ 28 Kc1 Rc4., followed by 29 ... Rb4 should win. Black has simply too many threats including nasty discovered checks. C) 27 Kb1 Rc4 followed by 28 ... Rb4 also looks winning although may lead to a longer King hunt.

Jul-31-24		TheaN: I weirdly combined both ideas of Bxa3 and Bf5, which works too though it may not be as consistent. I mainly wanted to prevent Rd2 as defense, so started with <25....Bxa3 26.bxa3> which opens up the b-file so Qb1+ is a threat too. White can decline the bishop, mainly through 26.Rd2 but considering he has no compensation whatsoever losing a3 is detrimental as Black now has 26....Bb4 -+ piling up on the pinned knight. Rxc3+ -+ works too but is not necessary, Rd8?! ∓ is worse after 27.Qa4! and White clings on. <26....Bf5>: click for larger view Somehow this felt stronger than Qxa3+ or 25....Bf5... threatening mate on c2 and 27.Rd2? Qb1#. What I missed was 27.Rd3?!, a defense that is a bit moot the move before as Black hasn't sacced anything yet. Now, White sacs the rook to defuse the attack. Problem is... it doesn't really work. 27....Rd8 -+ simply wins Rd3 down the line. Ne6 and Rc4 work too so White's simply busted. I'd try <27.Kd2 Rd8 28.Ke1 Rxd4 -+>: click for larger view White still gets ♖♘:♕♙, biggest issue is that the board's an open book. No hiding places whatsoever, rooks aren't coordinating and Black can almost immediately start grab a3 and run a7 down the board. In addition, natural moves like Ne6 with Rd8 will simply put White in more trouble: this is done.

Jul-31-24		cocker: 27 ... Qa2+ looks better than the move played. THEN play 28 ... Bf5.

Jul-31-24		chrisowen: I fact ends its uv Bxa3 its abridge lib eve its aad dank its ago quo Bxa3 co

Jul-31-24		King.Arthur.Brazil: Surely I was surprised by FH (fishouse) selected my move: 25... Bf5! For <TheaN>'s defense in here <26. Rd3!?> then the king proposes 26... Rc4. (If 27. Qe5?? Bxd3 and the mate threat again with an extra ♖). Therefore, 27. Qd5 (forced) Be4 (If 28. Qxe4?? Rxe4 29. Nxe4 Qxd3 or 28. Nd4 Rxc3+). So, I didn't find an remedy to 27... Be4, which wins the game. So the next moves of FH line are a little forced too, in my humble opinion. See, I didn't selected the game line (or best, I failled today); however, I feel happy to find a stronger one.

Jul-31-24		PawnSac: < King.Arthur.Brazil: > the Fish looked at Rd3 for a while then at higher ply switched to Rd2.

Jul-31-24		PawnSac: and no, you didn't fail today <grin> you found the correct idea to start. Good work!
