Sep-06-23		Brenin: 33 Rxa7+ Kxa7 (forced) 34 Bc5+ Kb8 35 Qxf2 leaves White ahead by B+2P.

Sep-06-23		Brenin: Black missed 30 ... Qxe7 31 Bxe7 Rxd1+ 32 Qxd1 Be3+ 33 Kb1 (33 Qd2 Rg1 mate) Nxd1, with R for 2P.

Sep-06-23		Allderdice83: < Brenin: 33 Rxa7+ Kxa7 (forced) 34 Bc5+ Kb8 35 Qxf2 leaves White ahead by B+2P.> There's better. 35. Qb5+, and then ... 35 ... Ka8 36. Qa6+ Kb8 37. Bd6# 35 ... Kc8 36. Qa6+ forces 36 ... Qb7 37. Qxb7+ Kxb7 38. Bxf2. Up by bishop and 2 pawns and the queens off the board. Otherwise ... 36 ... Kb8 37. Bd6+ or 36 ... Kc7 37. Bb6+ Kc6 (or Kb8 38. Qa7+ Kc8 Qc7#), 38. Bxf2+ Kc7 39. Bb6+ Kc6 40. Ba7+ Kc7 41. Qb6+ Kc8 42. Qb8# or 35 ... Qb7 36. Qxb7+ (only because I can't find anything better) Kxb7 37. Bxf2.

Sep-06-23		Allderdice83: Excuse me, in the middle there, that should read 36 ... Kb8 37. Bd6#

Sep-06-23		Allderdice83: <Brenin: Black missed 30 ... Qxe7 31 Bxe7 Rxd1+ 32 Qxd1 Be3+ 33 Kb1 (33 Qd2 Rg1 mate) Nxd1, with R for 2P.> Yeah, that's a serious miss, although I think White can do better. 30 ... Qxe7 31. Nc7+ Kb7 32. Qb5+. Now 32 ... Kc8?? loses outright to 33. Qa6+ Kd7 (33 ... Kb8 34. Nd5+ Ka8 35. Nb6#), 34. Bxe7+ Nxd1 35. Bxd8, so instead ... 32 ... Bb6 33. Qd5+ the only move that saves White: 33 ... Kc8 34. Qa8+ Kd7 35. Bxe7+ Nxd1 36. Bxd8 Rg1 37. Qd5+ Kc8 38. Qa8+ Kd7 39. Qd5+ Kc8 with a draw by repetition (Black was threatening 37 ... Nc3+ 38. Kd2 Rd1#, and after 37. Qd5+ Kc8 38. Qxd1?? Black has 38 ... Be3+ 39. Kb1 Rxd1#) 33 ... Kb8 34. Ne6+ Ka7 35. Nxd8 Qxd8 36. Qxf7+ Ka8 37. Qd5+ Ka7 38. Qf7+ Ka8 again is a draw by repetition.

Sep-06-23		al wazir: What was wrong with 25...Nf2 ?

Sep-06-23		stacase: Sometimes it's as obvious as the North end of a South bound goat. Love that [ANALYSIS] bar I came up with this continuation: 34...Kb7 35. Qb5+ Kc7 36. Bd6+ Kd8 37. Qb8+ Kd7 38. Qc7+ Ke8 39. Qe7#

Sep-06-23		King.Arthur.Brazil: My option is: 33. Rxa7+ Kxa7 34. Bc5+ A)Ka8 35. Qa6+ Kb8 36. Bd6# B) Kb7 35. Qb5+ Kc8 36. Qa6+ Kb8 37. Bd6# C) Kb7 35. Qb5+ Ka8 36. Qa6+ Kb8 37. Bd6# Therefore, B is forced to: 34... Kb7 35. Qb5+ D) Ka8 36. Qa6+ Kb8 37. Bd6#. E)Kc7 36. Bd6+ Kc8 37. Qb8+ Kd7 38. Qc7+ Ke8 39. Qe7# F)Kc7 36. Bd6+ Kd8 37. Be5+ (Kc8 38. Qb8#) Ke7 38. Qd7+ Kf8 39. Qd8# G) Qb7 36. Qxb7+ Kxb7 37. Bxf2 if Rg2 38. Bg3 or Rg5 38. Rd5 (Kc6 39. Rxa5) or 38... Ka6 39. Rd6+ Kb5 40. Rf6, with easy win.

Sep-06-23		King.Arthur.Brazil: I guess that B wins with <Brenin>'s line: <30...Qxe7 31. Bxe7> Be3+ 32. Kb1 Rxd1+ 33. Qxd1 Nxd1. More complex is the case when: 32. Rd2 Rxd2 33. Nc7+ Kb8 34. Na6+ Kc8 35. Qc4+ Kd7 36. Qc7+ Ke8 37. Qc8+ Rd8+ 38. Kb1 Rg1# or even 36. Qb5+ Kxe7 when any other Q check is answered by ♖ interposition check as: 36. Qb7+ Rd7+ 37.Kb1 Rg1#. Or 37. Qe5+ Kf8 (38. Qb8+ Rd8+) 38. Qxe3 Rd1#. <Alderdice83> If W plays 31. Nc7+ Qxc7 32. Bxc7 Rxd1+ 33.Qxd1 Nxd1... with an extra ♖. In this case, B cannot play 32. Be3 + Rd2 33. Rxd2?? because of 34. Qa6+ Ba7 35. Qc6#.

Sep-06-23		mel gibson: We had an "embarras de richesse" Stockfish 16 says: 33. Re1 (33. Re1 (Rd1-e1 Nf2-d3+ Qf1xd3 Qf3xd3 c2xd3 Ba7-b8 Rc7-d7 Bb8xd6 Rd7xd6 Rg8-c8+ Kc1-d2 Rc8-c7 Re1-e8+ Ka8-b7 Re8-f8 b4-b3 a2xb3 Rc7-e7 Rd6-f6 Kb7-c7 Rf8xf7 Re7xf7 Rf6xf7+ Kc7-d6 h2-h4 Kd6-e5 h4-h5 a5-a4 b3xa4 Ke5-d6 h5-h6 Kd6-d5 h6-h7 Kd5-e5 h7-h8Q+ Ke5-f4 Rf7-g7 Kf4-e5 Rg7-g6+ Ke5-f4 Qh8-h4+ Kf4xf5 Qh4-e4+) +M22/63 199) White wins _ mate in 22. But following the text move: 33. Rxa7+ Kxa7 (33. .. Kxa7 (Ka8xa7 Bd6-c5+ Ka7-b7 Qf1-b5+ Kb7-c8 Qb5-d7+ Kc8-b8 Qd7-a7+ Kb8-c8 Bc5xf2 Qf3-f4+ Bf2-e3 Qf4-c7 Qa7-a6+ Qc7-b7 Qa6xa5 Qb7-c7 Be3-b6 Qc7-c6 f5-f6 Kc8-b7 Bb6-f2 b4-b3 a2xb3 Rg8-e8 Rd1-d5 Re8-e2 Qa5-a7+ Kb7-c8 Rd5-c5 Qc6xc5 Qa7xc5+ Kc8-d7 Qc5-d5+ Kd7-c7 Qd5-c4+ Kc7-b8 Qc4xe2 Kb8-b7 Qe2-e7+ Kb7-c6 b3-b4 Kc6-d5 b4-b5 Kd5-c4 Qe7-c5+) -M23/59 250) White wins _ mate in 23.

Sep-06-23		Jimfromprovidence: After the text line 33 Rxa7+ Kxa7 34 Bc5+, instead of resigning black plays 34...Kb8. White has the clever 35 Bxf2, threatening 36 Ba7+ click for larger view

Sep-06-23		agb2002: White has a rook and two pawns for a knight. Black threatens 33... Qxd1+ 34.Qxd1 Nxd1 35.Kxd1 Rd8 36.Rc6 Kb7. The Black's light pieces lie on the diagonal a7-g1. This suggests, 33.Rxa7+ Kxa7 34.Bc5+: A) 34... Ka8 35.Qa6+ Kb8 36.Bd6#. B) 34... Kb7 35.Qb5+ B.1) 35... Ka8 as in A. B.2) 35... Kc7 36.Qb6+ Kc8 37.Bxf2 wins decisive material. B.3) 35... Kc8 36.Qd7+ Kb8 37.Qa7+ Kc8 38.Bxf2 as in B.2. C) 34... Kb8 35.Qb5+ Qb7 (else transposes to B) 36.Qxb7+ Kxb7 37.Bxf2 + - [B+2P].

Sep-06-23		TheaN: Honestly I kind of stopped after <33.Rxa7+ Kxa7 34.Bc5+ +-> picking up a piece and winning. OTB I'd probably looked for the checks after also... bit on the easy side for a Wednesday.

Sep-06-23		MissScarlett: <33. Rxa7+ Kxa7 34. Rd2> also works.

Sep-06-23		chrisowen: I'd yen lucid guff it's v it's o up Rxa7 abc claw it's Re1 feel aeschylus it's oh bag bug q babel uba it's v Rxa7 it's oe Re1 bud;

Sep-06-23		Sastre: <al wazir: What was wrong with 25...Nf2 ?> 25...Nf2 26.Qf3.

Sep-06-23		TheaN: <MissScarlett: <33. Rxa7+ Kxa7 34. Rd2> also works.> It does, but regardless of followup I'd argue that Bc5+ is much stronger. The rook's already well placed, d7 gets revealed and it comes with tempo, so three birds one stone pretty much. Analysis shows, Rd2 is +3 which can be fumbled, whereas the +8 after Bc5+ with Qxf2 shouldn't.

Sep-06-23		Refused: 33.Rxa7+ Kxa7 34.Bc5+ and collect material on f2 looks like an easy way to make this +-. Maybe White has soemthing better, but I am too lazy to look.

Sep-06-23		Refused: <Allderdice83: <Brenin: Black missed 30 ... Qxe7 31 Bxe7 Rxd1+ 32 Qxd1 Be3+ 33 Kb1 (33 Qd2 Rg1 mate) Nxd1, with R for 2P.> Yeah, that's a serious miss, although I think White can do better. 30 ... Qxe7 31. Nc7+ Kb7 32. Qb5+. Now 32 ... Kc8?? loses outright to 33. Qa6+ Kd7 (33 ... Kb8 34. Nd5+ Ka8 35. Nb6#), 34. Bxe7+ Nxd1 35. Bxd8, so instead ... 32 ... Bb6 33. Qd5+ the only move that saves White: 33 ... Kc8 34. Qa8+ Kd7 35. Bxe7+ Nxd1 36. Bxd8 Rg1 37. Qd5+ Kc8 38. Qa8+ Kd7 39. Qd5+ Kc8 with a draw by repetition (Black was threatening 37 ... Nc3+ 38. Kd2 Rd1#, and after 37. Qd5+ Kc8 38. Qxd1?? Black has 38 ... Be3+ 39. Kb1 Rxd1#) 33 ... Kb8 34. Ne6+ Ka7 35. Nxd8 Qxd8 36. Qxf7+ Ka8 37. Qd5+ Ka7 38. Qf7+ Ka8 again is a draw by repetition.> 30...Qxe7! 31.Nc7+ Qxc7 shrug Unless I am missing something, I think you just threw a good knight after a bad rook.
