  Penguincw: Hmm, after missing Monday's puzzle, can I get the Tuesday and Wednesday puzzle?

And well, I did, sort of. I treated this puzzle as a mid/late week puzzle (so aim to find the first move), which I got 44...Nfg4+ 45.hxg4 Nxg4+, but wasn't sure what to play next.

However, since that was all that was played in the game, I technically got this puzzle right. After looking at the position for a bit, I do see now that wherever white's king goes, it's going to be a fork.

The remaining endgame is a queen vs. bishop and 2 pawns. I think black can win this.

2/3 this week.

Aug-24-16  plumbst: Medium/Easy. Black is up a piece for 3 pawns.

The Knights provide the answer:

45.hxg4 Nxg4+

White loses his Queen to a fork on e3 or f2.

  patzer2: The exchange of two Knights for a Pawn and Queen via a Knight fork combination is the result of our Wednesday puzzle solution 44...Nfg4+ .

White's game goes down hill after 36. f5?, allowing 36...Bd6 . Instead, 36. Rc7 = holds it level.

Aug-24-16  iking: 44... Nfg4 ... boom!

  agb2002: Black has two knights for a bishop and three pawns.

A knight check from g4 would force the white king to a light square making possible a subsequent knight fork, that is to say, 44... Nfg4+ 45.hxg4 (45.Kh1 Nf2+ wins; 45.Kg2 Ne3+ wins) 45... Nxg4+ wins. For example, 46.Kh3 Nf2+ 47.Kh2 (47.Kh4 Qd8+ and mate in two) 47... Nxd1 etc.

Aug-24-16  et1: very beautiful...almost magical.
Aug-24-16  Abdel Irada: ∞

An embarrassment of forks.

Aug-24-16  YouRang: Wednesday 44...?

I (black) have a knight for three pawns and I have some attacking potential, but other than that I kinda struggled with this.

With great uncertainty, I settled on <44...Ne4>

The idea being to pile up on Pg3. I figured white would try <45.Bxe5 Bxe5>

So my N, R and B are all hitting Pg3, while my Q hits Ba4 and Pd5.

The Pg3 is attacked 3 times and defended 3 times, but white's problem is that two of its defenders are the queen and king, so it's really inadequate. White has to let the pawn go. I figured perhaps <46.Bb3> to at least get the bishop out of take and defend Pd5, but then <46...Nxg3>

...and without calculating further, I think black's in deep trouble.


Checking with the computer, I see that white could have better defended against 44...Ne4 with 45.Bd7! (of course, the engine knows that ...Ng5 is black's best move). Humanly, I would answer with 45...Rxd7 46.Bxe5 Bxe5 47.Qg4+ to win back a piece. Black ends up just a bit better.

Aug-24-16  AlicesKnight: I spent a while trying to work out how to bring the Black Q into it, but it seems she is not needed for the key parts! 44. Ng4+ (does it matter which N? - if White moves the K instead then the fork happens anyway); 45.hxg4 Nxg4+;
If 46. Kh1 or Kh3, then Nf2+ wins the Q.
If 46.Kg2, Ne3+ wins the Q (White can short-circuit with Qxg4 allowing Rxg4 of course). White has 47.Bxg7 Kxg7, 48.Rxd1 but at last the Black Q enters with Qxa4 leaving Q and B vs. R - adequate.
Aug-24-16  cocker: 44 Bxa4 was suicide.
Aug-24-16  mel gibson: Wow - 5 pieces bearing down on the white King.
That made it easy today.
Aug-24-16  Razgriz: What a Godly fork
Aug-24-16  MaczynskiPratten: Another position with lots of possibilities but when you see Ng4+ it's all over. Black was already a piece up but this is a very effective way to simplify and gain further material. I like all the different Knight fork patterns for all White's different King moves - with his own pieces stopping it going on to a black square to save the day ...

Aug-24-16  weary willy: Easier for me than Monday and Tuesday
Aug-24-16  WorstPlayerEver: Hmm.. not sure. At first sight it seems mate in 18 moves.
Aug-24-16  saturn2: Got it after some minutes. The knights can explore the weak squares f2 or e3 to give family check for king and queen.
Premium Chessgames Member
  Diademas: Cute combination.
Probably the first puzzle were the winning combination contains four consecutive knight moves.
Premium Chessgames Member
  kevin86: A cute horse rodeo; black wins the queen regardless of where white moves the king.
Aug-24-16  YouRang: *sigh* Now that I've had my morning coffee, it seems so simple. I shouldn't try to solve puzzles right before bedtime...

  Fusilli: <weary willy: Easier for me than Monday and Tuesday> Possibly because once you know it's "black to play and win" there is no other candidate move than the knight check. Still, I think it's appropriate for a Wednesday.

  Dionysius1: Very pretty. What took me longest was checking White hadn't enough compensation for the Queen at the end of the combination, what with the Black Rook under attack at g7.

Ah, yes, a good <knight>'s sleep cures what ails ya.
