  patzer2: The decoy 43. Rg6+! makes for a pretty finish, either deflecting the Black Queen from the defense of the c8 Qeening square or winning the Queen with a fork after 43...Kxg6 44. Nx4+ .

  patzer2: The Queen sacrifice 31. Qxg3! is strong and practically forced as a defense against Black's double threat of ...QxR or ...Rh3 pinning and winning the White Queen with interest.

  fredthebear: <patzer2> No doubt! This game had plenty of action. There's a bit of a knight windmill in here for those who collect such tactics.
Dec-21-19  JimmyRockHound: Black's 39th Qxa3 is a total bunder. It was a draw until then. (According to Stockfish. )

  An Englishman: Good Evening: Bit too easy for the weekend because White is in desperation mode and has to try extreme measures. 39...Qxa3 looked odd to me, too. 39...Qh3+; 40.Kg1,f3; 41.Rxg7+,Kh6 seemed like something a human might try, covering the c-pawn's queening square and advancing the f-pawn. What did Stockfish prefer?
Dec-21-19  Walter Glattke: Risk, better 34.Rxg7+ Qxg7 35.Rxg7+ Kxg7 36.Bxe5+ Kf7 37.c5 bxc5 38.Bxc5 Ke6 39.Bd6 with white advantage.
Dec-21-19  AlicesKnight: Found QxR and RxN as the likely break; it seemed enough to blunt Black's counters but the continuation was less clear to me. Agree with <patzer2>.
Dec-21-19  ndg2: I'm not really surprised by the queen sac. What surprises me is how strong the subsequent advance of the c pawn is. Black has no time and no opportunity to create any counterplay with his rook. Any threats by the black queen are reliably thwarted by the knight.
Dec-21-19  goodevans: <An Englishman: [...] 39...Qxa3 looked odd to me, too. 39...Qh3+; 40.Kg1,f3; 41.Rxg7+,Kh6 seemed like something a human might try, covering the c-pawn's queening square and advancing the f-pawn.>

That plan seems to fall foul of <42.Nf4>. Now where does the Q go? <42...Qc8> looks way too passive. <42...Qf5> might fare better but either way white has many more threats than black.

SF reckons that after <39...Qh3+ 40.Kg1> it's now OK to play <40...Qxa3>. The difference is that with the K on g1 <41.Rxg7+ Kh6 42.c7> can be answered with <42...Qc5+> winning the B, e.g. <43.Kh1 Qxe5 44.c8=Q Kxg7> with at least equality.

  agb2002: White has a bishop for three pawns.

Black threatens Qxd1+ and Rh3.

The only option seems to be 31.Qxg3 (31.Rxd7 Qf1+ 32.Qg1 Rh3#):

A) 31... Qxg3 32.Rxd7

A.1) 32... g6 33.Rg7+ Kf8 (33... Kh8 34.Rxg6+ e5 35.Rxg3 wins) 34.Rcc7 e5 (to prevent Rxh7-Rh8#) 35.Rcf7+ Ke8 36.Re7+ followed by 37.Bxe5 looks winning.

A.2) 32... Rd8 33.Rxg7+ Qxg7 34.Bxg7 Kxg7 35.Rc7+ and 36.Rxa7 + - [N vs p].

A.3) 32... Qf3 33.Rxg7+ Kf8 34.Rd6 (to prevent Qxc6 and Qd1+ trying to achieve perpetual) 34... Qe2 (34... Re8 35.Rdd7 Rc8 36.Bf6 looks winning) 35.Bf6 followed by Rdd7-Rh7 seems to win.

A.4) 32... Qh3+ 33.Kg1 doesn't seem to improve Black's position.

B) 31... Qxd1+ 32.Ne1 and the double threat Qxg7# and Rxe6 wins a pawn for White.

  WorstPlayerEver: 35... Re8=
Dec-21-19  goodevans: <agb2002> As always a pretty comprehensive analysis. You certainly considered more lines than I did.

<A.1) 32... g6 33.Rg7+ Kf8 [...] 34.Rcc7 e5 (to prevent Rxh7-Rh8#)...>

What would you do if black instead creates his own threat with <34...Rd8>? Now white doesn't have time for Rxh7.

If, on the other hand, you play <33.Bf6> before playing <34.Rg7+> then black looks hopeless.

<A.2) 32... Rd8 33.Rxg7+ Qxg7 34.Bxg7 Kxg7 35.Rc7+ and 36.Rxa7 + - [N vs p].>

I agree that this is probably winning but wouldn't <33.Rxd8+> be simpler?

<A.3) 32... Qf3 33.Rxg7+ Kf8 34.Rd6 (to prevent Qxc6 and Qd1+ trying to achieve perpetual) 34... Qe2...>

Black has quite a few other options on move 34, e.g. <34.Qfl+>, <34.Qh5+> or <34.f4> so I don't think this is so clear cut. Also, similar to <A.1> white might benefit by delaying Rxg7+ since there's little black can do to prevent it. Why not play <33.Rcc7> first?

Anyway, thanks for giving me so much more to think about.

  Willber G: I went for 31.Rcd6 which the engine gives as slightly better than the game line.
Dec-21-19  stacase:   
This is another obvious Monday Queen sacrifice, What else could it be? And then it pretty much plays itself after that.
Dec-21-19  mel gibson: Stockfish 10 is calling it a draw:

31. Qxg3

(31.Qxg3 (♕h2xg3 ♕f3xg3 ♖d1xd7 e6-e5 ♖c6-c7 h7-h5 c4-c5 b6xc5 b4xc5 ♖a8-e8 ♖c7xa7 ♖e8-e6 ♖d7xg7+ ♕g3xg7 ♖a7xg7+ ♔g8xg7 ♘g2-f4 ♖e6-e8 ♘f4-d3 ♔g7-f6 ♔h1-g2 ♔f6-e6 ♗b2xe5 ♖e8-a8 ♗e5-d6 ♖a8xa3 ♘d3-f4+ ♔e6-d7 ♘f4xh5 ♖a3-d3 ♗d6-e5 ♔d7-c6 ♘h5-f4 ♖d3-e3 ♗e5-d6 ♖e3-c3 ♔g2-f2 ♖c3xc5 ♗d6xc5 ♔c6xc5 ♔f2-e3 ♔c5-c4 ♘f4-g6 f5-f4+ ♔e3xf4 ♔c4-d5 ♔f4-g4 ♔d5-c5 ♘g6-f4 ♔c5-b5 ♔g4-f5 ♔b5-c5 ♔f5-e4 ♔c5-d6 ♘f4-h5 ♔d6-e7) +0.09/42 126)

score for White +0.09 depth 42.

However in the game Black makes a big mistake at 39....Qxa3. Black should have played 39... Qh3+

Dec-21-19  Andrew Chapman: Why 38..f4 rather than h4?

Dec-21-19  RandomVisitor: Since the 29...Qe3+ 30...Qf3 line is drawn, black had best try something else earlier, such as 28...Qg4:

34.Rcc7 is a mistake which only leads to perpetual. I did see 34... Rd8 but forgot it or made a mess. Writing the post after having 'solved' it may have these problems, in particular when being in a rush.

<If, on the other hand, you play <33.Bf6> before playing <34.Rg7+> then black looks hopeless.>

33.Rcc7 with the idea of playing Re7 with tempo by creating mating threats while avoiding Rd8 is probably strongest. For example, 33... e5 34.Rg7+ Kf8 35.Rxh7 Kg8 36.Rcg7+ Kf8 37.Rd7 Kg8 38.Rhe7.

<<A.2) 32... Rd8 33.Rxg7+ Qxg7 34.Bxg7 Kxg7 35.Rc7+ and 36.Rxa7 + - [N vs p].>

I agree that this is probably winning but wouldn't <33.Rxd8+> be simpler?>

This is just a typo. I meant 32... Re8, to support e5.

<<A.3) 32... Qf3 33.Rxg7+ Kf8 34.Rd6 (to prevent Qxc6 and Qd1+ trying to achieve perpetual) 34... Qe2...>

Black has quite a few other options on move 34, e.g. <34.Qfl+>, <34.Qh5+> or <34.f4> so I don't think this is so clear cut. Also, similar to <A.1> white might benefit by delaying Rxg7+ since there's little black can do to prevent it. Why not play <33.Rcc7> first?>

I agree, 33.Rcc7 again looks strongest, as above.

<Anyway, thanks for giving me so much more to think about.>

Thanks to you for pointing out these mistakes!
