Mar-10-21		Cheapo by the Dozen: <Cecco> is of course right. What I missed, after not seeing quick mates, is that Black gains material with check.

Mar-10-21		al wazir: My line was <32...Ndf3+ 33. gxf3> Nxf3+ 34. Kf1 (34. Kh1 Qh2#; 34. Kg2 Nxe1+ 35. Qxe1 Qxc4, winning an exchange and a ♙) 34...Qxc4+ 35. Re2 Nd2+ 36. Kg2 Nxb1, winning a piece and a ♙.

Mar-10-21		Walter Glattke: Nc4 unguarded, 32.-Ndxf3+ 33.gxf3 Nxf3+ 34.Kf1 (Kh1 Qh2#/Kg2 Nxe1+) Qxc4+ 35.Re2 Nd2+36.Kg1 Nxb1 34.Kd2 +- in the match. Tartakower: "Never won a match by resign"

Mar-10-21		saturn2: After 32.. Nd3 is a discovered attack on the Nc4 The only reasonable king move is 33.Kf1 Qxc4+ piece And if 33 gxf3 Nxf3+ 34 Kg2 then Nxe1+ followed by Qxc4 wins an exchange

Mar-10-21		saturn2: 30.Nd6 is impressive only at first thought

Mar-10-21		drollere: this is murkier than it seemed at first view. i had 32. .. Ndf3+, 33. gxf3 Nxf3+, 34. Kf1 Qxc4+, 35. Kg2 Nxe1+, 36. Qxe1 ...

Mar-10-21		rodchuck: What happens after 32...Ndf3+ 33. gxf3 Nxf3+ 34. Kf1 Qxc4+ 35.Qe2? White seems OK

Mar-10-21		agb2002: Black has a bishop for a knight. White threatens Qxf4. The position of the white pieces, the knight is defenseless, suggests 32... Ndf3+ 33.gxf3 (33.Kf1 Qxc4+ wins; 33.Kh1 Qh2#) 33... Nxf3+: A) 34.Kh1 Qh2#. B) 34.Kg2 Nxe1+ 35.Qxe1 Qxc4 - + [r+p vs B]. C) 34.Kf1 Qxc4+ C.1) 35.Kg2 Nxe1+ transposes to A.2. C.2) 35.Qe2 Qxe2+ 36.Rxe2 (36.Kxe2 Nxe1) 36... Rd1+ 37.Kg2 Nd4 38.Bc2 Rc1 wins decisive material. C.3) 35.Re2 Rd1+ 36.Kg2 Nh4+ 37.Kg3 Rxb1 wins decisive material.

Mar-10-21		agb2002: 30.e6 is winning: 30... Nxe6 31.Rxe6 Rd1+ (31... fxe6 32.Qxg7#) 32.Re1. 33... Qxf3 I either a transcription error or yet another blunder: 34.Be4 wins.

Mar-10-21		AlicesKnight: I found the main lines that I see <agb2002> has given. The gameline looks wrong.

Mar-10-21		Brenin: Is there also a transcription error around moves 29-30? As <agb2002> has pointed out, 30 e6 Nxe6 31 Rxe6 looks like an obvious winning line, which was hard to miss. Note that 30 ... f6 loses the Q to 31 Ne7+ and 32 Ng6+.

Mar-10-21		mel gibson: I wasn't sure but I knew it was one of the Knights to give check on f3. As it turns out it doesn't matter which one. Stockfish 13 says: 32. .. Ndf3+ (32. .. Ndf3+ (♘d4-f3+ g2xf3 ♘g5xf3+ ♕e3xf3 ♕f4xf3 ♗b1-e4 ♕f3xh3 ♘c4-d6 f7-f6 ♗e4-g2 ♕h3-e6 ♘d6-b5 ♕e6-f5 ♘b5-d6 ♕f5-f4 a2-a4 f6xe5 ♘d6-e4 h6-h5 ♖e1-f1 ♕f4-g4 b2-b3 ♖d8-f8 ♔g1-h1 ♔g8-h7 a4-a5 b6xa5 ♖f1-a1 ♔h7-h6 ♖a1-f1 g7-g5 ♖f1-e1 a5-a4 b3xa4 c5-c4 ♖e1-f1 ♔h6-g7 ♔h1-g1 a7-a5 f2-f3 ♕g4-f4 ♖f1-d1 g5-g4) +7.09/36 212) score for Black +7.09 depth 36 HOWEVER - as per the game - White INCORRECTLY RESIGNS AT 33! White can play 34 Be4 or 34 Nd6 to win. 34. Nd6 (♘c4-d6 ♘g5xh3+ ♔g1-f1 ♘h3-g5 ♗b1-e4 ♕f3xe3 ♖e1xe3 ♘g5xe4 ♖e3xe4 ♔g8-f8 ♖e4-a4 ♖d8-d7 ♘d6-c8 ♖d7-d8 ♘c8xa7 ♖d8-a8 ♖a4-a3 g7-g5 ♘a7-b5 ♖a8xa3 ♘b5xa3 ♔f8-e7 ♘a3-c4 b6-b5 ♘c4-d6 b5-b4 ♘d6-f5+ ♔e7-e6 ♘f5xh6 ♔e6xe5 ♘h6xf7+ ♔e5-d4 ♘f7xg5 ♔d4-d3 ♘g5-f3 b4-b3 a2-a4 ♔d3-c2 a4-a5 c5-c4 a5-a6) +3.93/32 26 score for White +3.93 depth 32

Mar-10-21		saturn2: <rodchuck 32...Ndf3+ 33. gxf3 Nxf3+ 34. Kf1 Qxc4+ 35. Qe2 - Qxe2+ > 36. Rxe2 (Kxe2 Nxe1) Rd1+ 37. Kg2 Ne1+ 38. Kf1 Rxb1 39. Rxe1 Rxe1+ 40- . Kxe1 pawn ending with plus pawn for black

Mar-10-21		TheaN: Yeah pretty sure this should be <32....Ndf3+ 33.gxf3 Nxf3+ 34.Kf1> 34.Kg2 Nxe1+ with Qxc4 -+, Kh1 Qh2# whoops. <34....Qxc4+ 35.Re2> now 35.Qe2 allows Black to simplify 35....Qxe2+ 36.Rxe2 (else Nxe1) Rd1+ 37.Kg2 (else Rxb1) Ne1+ 38.Kf1 Nd3+ -+. Rxb1 probably wins but why make it harder on yourself. <35....Rd1+ 36.Kg2 Nh4+ -+> and Rxb1 follows with an uncoordinated White camp.

Mar-10-21		King.Arthur.Brazil: I really don't know why did white resign... I see the following line (I guess is not the "best" but) 34. ♕xf3 ♘xf3+ 35. ♔f1 ♘xe1 36. ♔xe1 ♖d4 37. b3 ♔f8 38. a4 a6 39. ♗f5 g6 40. ♗g4 h5 41. ♗f3 ♖f4 42. ♔e2 b5 43. axb5 axb5 44. ♘d6 c4 45. bxc4 bxc4 46. ♔e3 c3 47. ♗d1 ♖h4 48. f3 ♖xh3 49. ♔d3 ♖h1 50. ♗c2 ♖h3 51. ♗d1.

Mar-10-21		knaugle: We need to start noting 32. ... Qxf3?? It throws away the win. White resigned on reflex.

Mar-10-21		Cellist: rodchuck: "What happens after 32...Ndf3+ 33. gxf3 Nxf3+ 34. Kf1 Qxc4+ 35.Qe2? White seems OK" Best continuation may be 35. ... Nd2+ and then trade Queens. I think Black comes out a piece ahead. For example: 35...Nd2+ 36.Kg2 Qxe2 37.Rxe2 Nxb1.

Mar-10-21		TheaN: Actually, in hindsight, Black might want to opt for 32....Ndf3+ 33.gxf3 Nxf3+ 34.Kf1 Qxc4 35.Qe2 Qxe2+ 36.Rxe2 Rd1+ 37.Kg2 Ne1+ 38.Kf1 Rxb1: click for larger view Of course, 38....Nd3+ is objectively superior to Rxb1, but I do like the hopelessness offered to White. As after 39.Rxe1 Rxe1+ 40.Kxe1 Kh7: click for larger view Fastest route to f5 where Black can just hold until White has to commit, up a pawn and a free queen side majority. This is a trivial end game and might end sooner than with rooks on the board.

Mar-10-21		Refused: Went with 32...Ndf3+ 33.gxf3 Nxf3+ 34.Kf1 Qc4+ 35.Qe2 Qxe2+ 36.Kxe2 Nxe1 (36.Rxe2 Nd2+ 37.Ke1 Nxb1) I really don't get the game continuation with 33...Qxf3 is there any immediate kill that stops white from playing 34.Qxf3 Nxf3+ 35.Kf1 Nxe1 36.Kxe1 that I missed

Mar-10-21		RandomVisitor: 365chess.com lists this game and agrees that the losing 33...Qxf3 was in fact the move played.

Mar-10-21		Jambow: <Refused> I'm asking the same thing as you are two minor pieces vs rook + pawn I would take by choice?

Mar-10-21		RandomVisitor: After 33...Qxf3?! game over, for black... click for larger view Stockfish_21030721_x64_modern: <41/70 02:17 +4.29 34.Nd6> Nxh3+ 35.Kf1 Qxe3 36.Rxe3 Nf4 37.Bd3 Kf8 38.Bc4 Rd7 39.Bb5 Rd8 40.Ra3 a5 41.Rb3 g5 42.Bc4 Ng6 43.Rxb6 Nxe5 44.Be2 a4

Mar-10-21		Tiggler: WALOR- what a load of rubbish.

Apr-01-21		perfidious: While I trust much of what is posted on 365chess, hard to believe the denouement was, in fact, 33....Qxf3.
