40. Rxg8+ Kxg8
(else, e.g. after 40...Kf7: Queen is lost)
41. Qh8+ and the queen on a8 is gone
|Nov-13-17|| ||patzer2: Today's Monday puzzle (40. ?) solution is the easy skewer tactic 40. Rxg8+ Kxg8 41. Qh8+ Kf7 42. Qxa8 +-.|
For a Black improvement, I'd ditch the whole idea of pitching a pawn in the opening with 6...b5?! 7. cxb5 ±. Instead, if you must give up a pawn here, play the Benko Gambit with 3...b5 4. cxb5 a6 when Black gets more play for the gambit pawn.
|Nov-13-17|| ||al wazir: 37...f6 was black's only defense. If 38. f3 or 38...Qh7, then 38...Qd5. If 38. Qc4, then 38...d5.|
|Nov-13-17|| ||patzer2: White lets Black back in the game with the overly timid 22. b3? allowing 22...Ne8 = (0.02 @ 32 ply, Stockfish 8).|
Instead, the bold 22.Qxc7 Rxb2+ 23.Kd3 Nxf1 24.Qxe7 h6 25.Qe8+ Kh7 26.Qxf7 +- (+3.61 @ 29 ply, Stockfish 8) is immediately winning.
|Nov-13-17|| ||patzer2: After holding on for quite a while after 22...Ne8 =, Black slips up with 34...Nxd5? allowing 35. Rxh7 ±.|
Instead, simply 34...Bd8 = or 34...h6 = holds it about level.
Black's final decisive mistake was 35...Nf6? allowing 36. Rh8+ Ng8 37. Qc2! +- (+3.03 @ 27 ply, Stockfish 8). Necessary instead was 35...Bd8 36. Ke2 Ke7 37. Rd1 Qxa2 38. Qxa2 Nc3+ 39. Kf3 Nxa2 40. Ra1 Nb4 41. Rxg7 Ke6 ± (+0.53 @ 32 ply, Stockfish 8) with drawing chances.
|Nov-13-17|| ||ThumbTack: 35... Bd8 would have saved the game, but after 35...Nf6, Black is in bad shape.|

Nope, nothing is too easy for Monday.|
|Nov-13-17|| ||morfishine: No Mato for Mato, but his Queen is lost after <40.Rxg8+> followed by <41.Qh8+>|
|Nov-13-17|| ||malt: Same as <lost in space>|
|Nov-13-17|| ||Cheapo by the Dozen: The obvious try for a mating attack fails as a mating attack -- but it wins massive material as a very nice consolation.|
|Nov-13-17|| ||Oxspawn: <malt>, <lost in space> ... yes you already know the ending but think how much pleasure you get in playing through the game and seeing how black achieves his doom. Like a movie which tells you the story in a flashback; finally you arrive at the tragic point where you began...|
|Nov-13-17|| ||zb2cr: 40. Rxg8+ begins a sequence which causes the loose Black Queen on a8 to be lost. Either Black's King steps aside at once (40. ...Kf7; 41. Rxa8) or he is forced to do so (40. ... Kxg8; 41. Qh8+, Kf7; 42. Qxa8).|
|Nov-13-17|| ||malt: <Oxspawn> I'll give a stab
(42...ef3 43.Qd5+ Ke8 44.Qe6 Kd8 45.Rh8+ Kc7 46.Qc8+ Kb6 47.Qd7)
43.Rh5 ef3 44.B:c5! R:g4 45.Qd5+ Kd7
45.Qf5+ Kc7 46.Q:g4 dc6 47.Q:g7 Kd6
|Nov-13-17|| ||patzer2: After 38...Rb4?, the move that sets up today's easy Monday puzzle combination is 39. Qh2! +- (mate-in-13, Stockfish 8 @ 32 ply).|
If instead of 38...Rb4? Black plays 38...Bh6 (diagram below), finding a strong winning line gets quite a bit more complicated.

After 38...Bh6 (diagram above), Stockfish 8 gives the strongest winning line as 39.g5 Ba1 40.Bf4 +- (+2.68 @ 33 ply) when play might continue 40...Ke7 41.fxe4 Kd7 42.Kd1 Qa6 43.Qe2 Qxe2+ 44.Kxe2 Bd4 45.Kd3 g6 46.R8h7 Ke6 47.Rf1 Rf8 48.Bd2 Ne7 49.Bc3 Nc6 50.Bxd4 Nxd4 51.Rf6+ Ke7 52.Rxg6 Ne6 53.Rgh6 Nxg5 54.Rh8 Rxh8 55.Rxh8 Nf3 56.a4 Ne5+ 57.Kc3 Nc6 58.Rh1 Ke6 59.Rf1 Nd4 +- (+15.98 @ 30 ply).
|Nov-13-17|| ||kevin86: White dominates the h file with the three major, then firces his way to a8 and the adverse queen.|
|Nov-13-17|| ||ChessCoachClark: Excellent game for showing the Battering Ram and (Royal) Skewer tactics to students.|
|Nov-13-17|| ||Bubo bubo: 40.Rxg8+ lures the black king into a skewer: 40...Kxg8 41.Qh8+ Kf7 42.Qxa8|
|Nov-13-17|| ||patzer2: <ChessCoachClark> Good point about 39. Qh2! +- being an instructive "Battering Ram and (Royal) Skewer" tactic.|
However, it's not something your students can put on automatic pilot and expect to work every time.
For example after 38...Bf6, the attempt 39. Qh2? allows 39...Ke7 ⩲ (best is 39. g5! +-) when Black is back in the game with a fighting chance.
