| Jun-30-18 | | RandomVisitor: 24...Nc4 apparently is no better:

| Jun-30-18 | | cunctatorg: Wow; 36. Re2 seems to also lose to 36... Nxa2.
a) 37. Kb1 Qb6 and 38... Qb2#
b) 37. Kd1 Qd5 38. Rd2 cd2 39. Qxd2 Qxd2 40. Kxd2 and now -perhaps- 40... f6 (with the idea 41... g6) -+Just two variations with only a few moves and it's hard to believe it! Either inexperience or 35... Qg2!! |

 | | Jimfromprovidence: I looked at 34 Qf1 in anticipation of 34...Qg1+ but black still wins with 34...Qd4, below.
click for larger viewThere are two threats 35...Qd2+ and 35...Nxa2+.
If, for example, white tries 35 Kb1 then 35...Qd5 wins.

| Jun-30-18 | | agb2002: Black has a knight and a pawn for a rook.
White threatens Qxf7.
Black can try to create a mating net with 32... d3 33.Qxd3 (33.cxd3 Qb2+ 34.Kd1 Qd2#) 33... Nb4 (33... Qg1+ 34.Qd1 Qb6 35.Qxh5#): A) 34.Qxc3 Nxa2+ wins.
B) 34.Qd1 Qb2#.
C) 34.Qf1 Nxc2 (flashy; probably better is 34... Nxa2+ 35.Kd1 Qb1+ 36.Ke2 Qb5+ and 37... Qxe8) C.1) 35.Kxc2 Qb2+ 36.Kd3 (36.Kd1 Qd2#) 36... Qb5+ wins. C.2) 35.f6 Qb2+ 36.Kd1 Ne3+ 37.Rxe3 (37.Ke1 Qd2#) 37... c2+ wins. C.3) 35.Qg2 (to control c2) 35... Qb2+ 36.Kd1 Ne3+ wins. C.4) 35.Qe2 Qb2+ 36.Kd1 Qb1#.
C.5) 35.Qd3 Qb2+ 36.Kd1 Nb4 and the double threat Nxd3 and c2+ looks winning. D) 34.Qe2 Nxa2+ 35.Kd1 Qb1#.
E) 34.Qe3 Nxa2+ 35.Kd1 Qb1+ 36.Ke2 Qxc2+
E.1) 37.Kf3 Qxf5+ followed by c2 seems to win decisive material. For example, 38.Qf4 Qxf4+ 39.Kxf4 c2 40.Rc8 c1=Q+, etc. Or 38.Kg2 c2 39.Rc8 Qxc8, etc. E.2) 37.Kf1 Qxf5+ as above.
E.3) 37.Ke1 Qb1+ 38.Ke2 (38.Kd1 c2+ wins; else loses the queen or Qxf5+ as above) 38... Qb5+ (38... c2 39.Qf3 is unpleasant) E.3.a) 39.Ke1 c2 40.Rc8 Qb1+ followed by c1=Q wins decisive material. E.3.b) 39.Kf2(3) Qxf5+ as above.
E.3.c) 39.Kd1 Qf1+ 40.Kc2 (40.Qe1 Qd3+ 41.Qd2 Qxd2#) 40... Qxf5+ followed by c2 wins decisive material (41.Qd3 Nb4+ wins). E.3.d) 39.Qd3 Nc1+ wins (better than Qxe8).
F) 34.Qe4 Qg1+ (34... Qd6 35.f6+ g6 36.Rh8+ Kxh8 37.Qe8+ and mate in three) 35.Qe1 Qd4 (threatens Nxa2+ Kb1 Qb4+ and Qb2#) F.1) 36.Rb8 Nxa2+ 38.Kb1 Nb4 followed by the advance of the a-pawn. The queen, knight and c-pawn seem to control the game completely. F.2) 36.Kb1 Qc4 37.Kc1 Nxa2+ 38.Kd1 (38.Kb1 (38.Kd1 Qb4+ and mate next) 38... Qd5+ 39.Ke2 Qxf5 looks very good for Black (40.Kd1 Qd7+ or 40.Qd1 Qb5+ win the rook). |

That move of yours 39... Nc3+ is much, much better than the move 39... Qxd2 of mine though my move is probably a winning move also... |

| Aug-21-18 | | stacase: Push the "d" Pawn so Queenie has two spots to say check from. |

| Aug-21-18 | | patzer2: Did not previously see the Saturday Jun 30, 2018 puzzle, which was presented today as an "easy" Tuesday tactic. White's decisive mistake was 32. Qd5?, allowing 32...d3! -+ (-6.52 @ 32 ply, Stockfish 9). Instead, 32. f6! = (0.00 @ 27 ply, Stockfish 9) holds as play might go 32.f6 Qb2+ [not 32...d3? 33.Rh8+ Kxh8 (33...Kg6 34.fxg7+ Kf5 35.Qd5+ Ne5 36.Rxh5+ Kg6 37.g8=Q+ Kf6 38.Qxe5#) 34.Qf8+ Kh7 35.Qxg7#] 33.Kd1 Qb1+ 34.Ke2 Qxc2+ 35.Kf3 Qf5+ 36.Ke2 Qb5+ 37.Kf2 Qf5+ 38.Ke2 = with a draw by perpetual check. |
|
| Aug-21-18 | | patzer2: <Daniel Sarmiento> < Actually 32.-Ne7 seems to win the game for black.> If 32...Ne7, then 33. Rxe7 +- (+2.12 @ 29 ply, Stockfish 9) seems to win for White. |

It happens rarely but I think there is an error in your post because the queen cannot go to b2 after the knight has moved to b4. After 34 Qd1 black however has 34..Na2 |

| Aug-21-18 | | Akabara: I went for
32. Qb2 Kd1
32. Qxc2+ Kxc2
33. Nb4+ Kd1
34. Nxd5
I'm not sure there 2 passers+knight are enough to clean up the game, but it looked rather promising, I totally missed the mate and other lines… |
