Apr-19-17		patzer2: Black's decisive mistake was 37...Bg3?, allowing 38. Rg4+ (+5.13 @ 30 depth, Stockfish 8.) Instead, 37...Kf8 38. Kf1 (+1.03 @ 35 depth, Stockfish 8) keeps Black fighting for the draw. Earlier, 9...a6 = and 17...g6 = look to slightly improve the situation for Black. After our Wednesday puzzle solution 39. Rxd3! Rxg3 40. b6 Rb3 and the obstruction 41. Nb5! (+12.06 @ 27 depth, Stockfish 8), the passed pawn is unstoppable.

Apr-19-17		patzer2: <NBZ> Also winning after 40...Rd3 is 41. b7! Rd8 42. Nc8! Rd1+ 43. Kh2 Rb1 44. Nd6 Ke7 45. Nb5 .

Apr-19-17		ChessHigherCat: ChessHigherCat: The first move is obviously Rxg3, to avoid mate and gain a tempo for the pawn push. Now the only question is which pawn to push. The most advanced pawn and thus the most immediate threat suggests 40. b6, and if Rb3, 41. Nb5 blocks the rook's access to the passed pawn. If now Rd3, 42. a4 Rd8 44. a5 and it's all over now Baby Black.

Apr-19-17		stacase: Black threatens mate and White can't say check. So, does 39, Rxg3 work? Yes it does (-: Black takes Rook White advances Pawn and then Blocks with the Knight or it covers c8. Either way, White can't stop the Pawn and resigns.

Apr-19-17		AlicesKnight: 39.Rxg3 is almost "forced", but removes the guard on b8 for the QNP after 40.b6 and 41.Nb5 (if...Rb3). Let's see - yes. <NBZ> has shown the other line of importance.

Apr-19-17		cocker: The winning line began a move earlier.

Apr-19-17		morfishine: After <39.Rxg3> 39...Rxg3 40.b6 Rb3 <41.Nb5> the White queens because the rook has too Farago *****

Apr-19-17		Timi: What the? That's white's only move lol

Apr-19-17		Timi: No, it isn't... but I mean Rxg3 is obvious

Apr-19-17		saturn2: I think white can also promote the a pawn. 40 a5 Ra(b)3 41 a6 the two pawns and the knight form a fortress. If for example 41..Ke7 42 Nc6 Rxb6 43 a7 the rook cannot stop the pawn via the a file ore the 8 th rank.

Apr-19-17		Gilmoy: I actually solved the problem with colors reversed! Toggle all pieces and the a4-b5 pawns to the other color, and ... Rxg3 still wins (for Black)! <mirrormirror> 39..Rxg3 40.Rxg3 b4 41.R(d,e,f)3 b3 42.R*1 a3 is <2CPP6 vs R not under>, queening.</mirrormirror> Grumble ... can't easily post FEN any more since browsers ceased Java plugin support about 1 month ago.

Apr-19-17		Walter Glattke: White wins with 39.Kf1 Ra1+ 40.Ke2 Bb8 41.Nc6 or 39.-Ke8 40.Rc4, but, of course, it lasts longer.

Apr-19-17		Jimfromprovidence: There is also 39 Rxg3 Rxa4 40 b6 Rb4 41 Nc8 Ke8. click for larger view White's best move is _____?

Apr-19-17		Pasker: I would probably take that bishop anyway even if i don't see the pawn promotion trick out of panic :-)

Apr-19-17		wtpy: Jfp, I think Rd3 is a good place to start: Black's rook can never leave the b file, and his king is cut off so white should be able to march his king to queenside and win easily.

Apr-19-17		Marmot PFL: Rxg3, b6, Nb5 rather easy to find.

Apr-19-17		patzer2: <Jimfromprovidence> After <39...Rxa4 40.b6 Rb4 41.Nc8 Ke8>, Stockfish 8 gives two strong winning options with 42. Rd3 or 42. Nd6+: 42.Rd3 [42.Nd6+ Ke7 43.Rd3 Rb1+ 44.Kf2! e5 45.b7 Rb4 (45...Kd7 46.Nb5+ Kc6 47.b8=Q )46.Rd5 Ke6 47.Rb5 (#12 @ 38 depth, Stockfish 8)] 42...e5 43.b7 Rb1+ 44.Kf2! f5 45.Nd6+ Ke7 46.Rd5 Rb2+ 47.Ke3 Rb1 48.Rb5 (+55.52 @ 33 depth, Stockfish 8). The choice of 42. Rd3 or 42. Nd6+ in your puzzle position is a matter of preference, since both win decisively. The flashier option is 42. Nd6+!

Apr-19-17		Lambda: Black has a few options to try to stop the b-pawn, 40... Rd3 falls to an eventual Nc6. After 40... Rb3 41. Nb5 Rd3, getting the knight out of position, white just pushes the b-pawn to b7 and then advances the a-pawn, which gets to a6 just in time to stop the rook from taking on b7. And against Rg8 and moving the king, white just has Nc8. 39... Rxa4 is probably the best try, since it's not trivial to protect both the knight and the pawn, but even if white lost the pawn I think the ending would still be winning.

Apr-19-17		jffun1958: Wow, I got this one pretty quickly. Black is threatening 39. ... Ra1# 39. RxBg3 RxR 40. b6 Rb3 41. Nb5! and Black has no means to stop the b-pawn.

Apr-19-17		ChessHigherCat: <Jimromprovidence: There is also 39 Rxg3 Rxa4 40 b6 Rb4 41 Nc8 Ke8. What is white's best move.> 42. b7 is interesting. If R takes, N forks on d6. if Kd1, Nd6 followed by promotion and Rg8+, winning the rook. If Kd2, then?

Apr-19-17		ChessHigherCat: To answer my question, maybe if 37...Kd2, 38. Rb7 gets 3 pawns?

Apr-19-17		stst: To relieve the immediate mate (Ra1#) White has either to flee the K, or simply 39.RxB. After RxR, the two a/b pawns with the N can proceed to promote.

Apr-19-17		malt: 39.R:g3 R:a4 40.b6 Rb4 41.Nc8 Ke8 42.Rd3 looks stronger than 42.Rc3 (42.b7 Ke8)

Apr-19-17		Jimfromprovidence: <Patzer2> < After <39...Rxa4 40.b6 Rb4 41.Nc8 Ke8>, Stockfish 8 gives two strong winning options with 42. Rd3 or 42. Nd6+:> I saw 42 Rd3, keeping the king on e8 while setting up after say, 42...Rb2, 43 b7. click for larger view 43 b7 works because of the knight fork possibility 44 Nd6+. I never thought of 42 Nd6+. Thanks for that insight.

Apr-20-17		malt: Amendment (42.b7 Kd8) as King was already on e8
