Dec-01-15  agb2002: White is one pawn ahead.

Black threatens 29... fxg5.

White can deliver mate in three with 29.Ng6+ hxg6 30.Qh4+ Bh6 31.Qxh6#.

Dec-01-15  saturn2: Ng6 followed by Qh4 gets the full point
Dec-01-15  BxChess: Even one move earlier it seems that black has no defence to 28. Qxg5. I think 28 ? would make a good mid-week puzzle.
Dec-01-15  morfishine: White controls <g8> so <29.Nxg6+> works due to the follow up 29.Qh4+
Dec-01-15  Olsonist: So bishop diagonals seem to be the theme this week. I saw Ng6 immediately. It just leaps out.
Dec-01-15  ozu: <BxChess> was thinking the same exact thing
Dec-01-15  stacase: Another well placed Bishop, although not as far removed as yesterday's deciding sentinel.
Dec-01-15  kubbybulin: "Never play f6." - GM Ben Finegold

But on black's 17th, he made the fatal mistake, and thus comes mate in 3 on white's 29th...

29. Ng6 hg6 30. Qh4 Bh6 31. Qh6#

Dec-01-15  starry2013: Nice to see a Monday/Tuesday puzzle that looks like a checkmate puzzle and actually is one too.
Dec-01-15  zb2cr: All simple and forced. 29. Ng6+, hxg6; 30. Qh4+,Bh6; 31. Qxh63.
Dec-01-15  wooden nickel: The knight sac would have even worked a move earlier i.e. 28.Ng6+, however more complicated. Smyslov's solution first 28.Qxg5 wins much easier.

28.Ng6+ if hxg6 then 29.Qh3+ Kg7 30.fxg6 Kxg6 31.Bf5+ Kf7 32.Qh5+ Ke7 33.Qh7+ Bg7 34.Qxg7#

Dec-01-15  CHESSTTCAMPS: Not only is white a pawn up, the black position is extremely cramped and the lack of mobility makes defense difficult. Not surprisingly, white can force a mate-in-3 with 29.Ng6+
Dec-01-15  Checker2: "Always check; it may be mate."
Dec-01-15  Chess Dad: To me, this was much easier than yesterday. Delivering mate with the Queen is much easier to see than using a lowly pawn to deliver mate.

Even if it's mate in 3 vs. a mate in 2.

Dec-01-15  M.Hassan: A Knight sac and it is over!
29.Ng6+ hxg6(forced)
30.Qh4+ Bh6
31.Qxh6#
Dec-01-15  M.Hassan: What was the point of Black's Knight move on 25?
25..........Nb8 moving from d7 to b8
26.f5 Nd7 coming back to d7 from b8
Dec-01-15  Herma48852: Agreed with many if that today's was easier than yesterday's: 29.Ng6+ hxg6 30.Qh4+ Bh6 31.Qxh6#
Dec-01-15  kevin86: Black's position looks like a spring; but after three moves, the position sprung on him! lol The queen will mate on the h-file.

  Willber G: <wooden nickel: The knight sac would have even worked a move earlier i.e.

28.Ng6+ if hxg6 (etc)>

What if NOT 28...hxg6 but instead Kg7.

Dec-01-15  dfcx: looks much easier than yesterday. Black king is stalemated,

29.Ng6+ hxg6 30.Qh3/Qh4+ 31.Bh6 Qxh6#

Dec-01-15  BOSTER: No chance for Sanz to beat Smyslov with white bishop on e6.
Dec-01-15  wooden nickel: <Willber G: ...28.Ng6+... What if NOT 28...hxg6 but instead Kg7.> Looks like 29.Qxg5 still works and we still have the knight, but it gets fancy!

  gawain: 29 Ng6+ forces mate. Now I must examine the game to see how that wonderfully posted white bishop got to e6.
Dec-01-15  JimNorCal: Easier than Monday: the bishop controlling a key escape square is close to the action, not a world away at a3 :)

  FSR: Egad, what a crush. Dominguez Sanz gives a lesson in how not to play chess. Smyslov rolled over him like a truck.
