May-25-06  Fezzik: While I managed to get both yesterday's and today's puzzles, I have to say these were both quite hard. I spent about 3 minutes on yesterday's, and only 2 today. However, I was lucky in noticing that the Black Queen was very short of squares.

The puzzles definitely seem to be getting harder here!

May-25-06  mago de riga: A little hard for a thursday, but i solved it
May-25-06  TheBB: I saw the first few moves, but couldn't follow the combination until the queen finally fell....

So strictly speaking I have 4/4 this week! Yey!

May-25-06  TheBB: In fact, my own 19. Bd3 is suggested by Fritz over Rad1. Satisfied with myself now. =)
May-25-06  itz2000: 18. Nd4(!!), and the queen is trapped!
May-25-06  Marco65: <TheBB> So what does your Fritz suggest after 19.Bd3 Bc4 as suggested by <RandomVisitor>? It looks worse than 19.Rad1
May-25-06  Miacat: <itz2000> 18Nd4? the queen is not trapped and 18...exd4 white drops a knight? If 19 e5...dxc3 or Rd6
May-25-06  TheBB: <Marco65> One possibility is 20. Bxc5 gxf5 21. exf5 Qxf5 22. Nxe5

White is a pawn up with an otherwise better position. Exchanges on e5 should lead to a won endgame.

May-25-06  EmperorAtahualpa: I found 18.Nf5, but was thinking 19.g3 instead of the text move!
May-25-06  dakgootje: I join the club who found the first move, but then missed a reasonable defence for black and thus cant claim it as being solved as i failed to see Rd7.

It was quite obvious the queen was almost trapped, so my first try was g3 after which the queen of course escapes, then i tried to trap the queen at f6 which of course didnt work. Then i thought about trapping the queen by just blocking the f6-sqaure. then i found the right move, didnt see a good defence for black after 30 seconds, thought i solved it and saw it wasnt true lol

May-25-06  zb2cr: Found 18. Nf5, but I didn't see the correct followup to 18. ... Rd7. Too bad.:(
May-25-06  dalbertz: How about 19. Bd3 Bc4 20. Rad1 ?
May-25-06  WayneCramp: Most people are spouting utter bull, clearly g3 is just as good as Rad1; better even as it is far simpler, and wins a piece on the spot.
May-25-06  SaltiNeil: That's 4 for 4 this week, a first in personal history. I know I am gonna blow it tomorrow though.
May-25-06  devilwolfdog: I dont' think that g3 on move 19 wins material because of 19....Bc4 where white's queen ends up in the same predicament as black's queen. If white takes the bishop, black takes the knight on f3 and white's knight is still hanging on f5.

  kevin86: I got this one with my strange astigmatism:One Hawkeye and one Buckeye---big ten humor at its worst:)

I saw that a queen trap was in the offing-and the perfect cut-off move was ♘f5. It lands in a hive of three enemy pieces!

May-25-06  YouRang: Hmmm. I guessed that it was a queen trap. And I noticed that g3 gives the queen just one escape at f6.

I spent some time trying to figure out how to guard f6, before it finally occurred to me that I can block the path to f6 with 18. Nf5! Now, the g3 attack is inescapable. :-)

Okay, almost inescapable. :-p

I admit that I didn't consider all the complications that followed in the game, but I think I got the main point of the puzzle. :-)

May-25-06  HoopDreams: i found the solution in about a minute. i saw how after g3 the only escape square for the q would be f6. Then it was only a matter of trapping the queen with the blockade nf5!
May-25-06  chessmoron: Csom sounds like a computer name but then I found that he's human.
May-25-06  technical draw: You Csom you lose some.
May-25-06  aazqua: Beautiful stuff. I knew the queen had to be trapped but the first move didn't occur to me.

  patzer2: White's 18. Nf5! is a recent puzzle solution which serves as an obstruction or blockade in a combination to trap the Black Queen.

The followup 19. Rad1! prepares 23. Bd1! to close the Black Queen's last remaining escape routes.
