Jul-25-07  dzechiel: Medium/Easy. White to move. Material even, but white has a definite space advantage and black's pieces seem uncoordinated.

Well, very first thing I see is 30 Nxd6. This threatens the rook on b7, which has nowhere good to go. And, if 30...Qxd6 then 31 Bc5 wins the queen.

Perhaps there's something better, but this looks good enough for me.

Jul-25-07  resty: easy one
Jul-25-07  mkrk17: The whole board seems blocked with not much to do anywhere else. The only weak point is d6. Nxd6 wins the exchange for White.

Not a bad puzzle, as it took me around 2 minutes of staring to get the solution.

Jul-25-07  sataranj: i thought 30.Nxb5 and 30.f4
but couldnt find anything
Jul-25-07  Ashram64: Nxd6 and Qxd6 will create the Queen trap, black must loose material

nice game Irina

Jul-25-07  gilbertblondy: 11.hg
Jul-25-07  bakuazer: it took me 2-3 minutes, to get the first move, then i had to think a little for the rest. 33.c6 move is important. i wonder if 34.Na4 is the only one (certainly the best). what about 34.Rb3 b4xc3 35.c6xd7 Rb2 36.Bc2 ? i think this still wins for white but i did not analyze much.

Jul-25-07  mrbiggs: I got this one pretty quickly, but didn't get yesterday's.

I stopped looking once I realized that the rook was trapped, but I still think that counts.

  al wazir: Winning the ♕ is easy; winning the game less so.

After 32...b4, black is in a fair way to get three minor pieces in exchange for ♕+♙+♙. I didn't see *that* at move 30.

With moves 33--38, white gets a ♗ for two ♙s, and then it's pretty much over.

  FSR: Yeah, that was an easy one. Is "I. Krush" the perfect name for a chessplayer or what? It's like a judge being named Learned Hand or a baseball player being named Herb Score. (Then there's "Al Kaline," who should have been a chemist instead.)
Jul-25-07  vibes43: I missed it but wouldn't black have been better off with 30. ...Rb6?
Jul-25-07  wouldpusher: <vibes43> 30. ... ♖b6 31. ♗xb6 ♖xb6 32. ♘dxb5 and it's ♖+♙+♙ vs. ♗ in a losing position. White has two passed pawns and will soon advance after a few more exchanges.
Jul-25-07  laskereshevsky: HELLO FOLKS

the problem (for black of course)is that the ♖b7 can be not avoid to "die", cause the ♗e3 IS checking the only two squares at his disposition (...a7/b6) so, with or without 30..♕xd6 the black's position is almost hopeless.........

P.S.: took me about 15 seconds, cause i spended the firsts 10 searching for a king side sacrifice like: ♘xh6 or ♗xg5.....

in other hands, saw it in a first glance....

Jul-25-07  goldfarbdj: Swing and a miss for me. I did actually look at Nxd6 several times, but Bc5 just completely eluded me.
Jul-25-07  openingspecialist: Got 2days - missed yesturdays. I should get both of these over the board. I didn't think of 33. c6 as the best move - i prefered 33. Rb3. Not too sure though - both are winning.
Jul-25-07  SpecialK: After 10 seconds, it seems there's no way of forcing an early resolution by check mate... The forcing move seems to be Knxd6, and Black's only way of clawing back material is QxKn -- but this is losing!! OK -- Knxd6 is the move.
Jul-25-07  willyfly: I saw 30 ♘xc6 ♕xd6 but didn't see 31 ♗c5. If I had been playing Black I would have seen it though. I always get suspicious when my opponent appears to be giving something away. I fooled around with 30 ♗a7 for a while - didn't find anything there though. All told, I didn't put much effort into this one. Interesting game in that after 29 moves only four ♙s have been removed from the board.
Jul-25-07  Tactic101: Nxd6! = fini! Yeah, I was looking at some kingside sac, then this one game in. After Nxd6, the rook is attacked and has nowhere to run to and Qxd6, Bc5 and the queen is at death's door and the rest is just "cleaning up". Not hard.

Krush's play is quite exemplary. She literally captured the board (maybe more so because her opponent let her do so quite easily). Then, she finds this tactical shot. No wonder "Tactics arise from strategically superior positions". You may have control of the whole board, but without a tactic, your earlier play doesn't mean much. It's not the easiest thing to knock out a already helpless opponent.

Jul-25-07  eblunt: I got the basic idea ♘xd6 followed by ♗c5 trapping the ♕ but I didn't see the complications thrown in by 32 .... b4, so not sure if that really counts as a success today.
Jul-25-07  realbrob: A typical trap winning the Black queen or rook 30..Nxd6 31.Qxd6 Bc5. I'm quite surprised that Black played 10 more moves without the queen.
Jul-25-07  Rook in the 7th rank: Why resigned black so late?!
Jul-25-07  aazqua: Trivially easy
Jul-25-07  nateinstein: Yesterday took me 6-7 minutes. Today takes me 6-7 seconds.
Jul-25-07  patzer2: For today's solution, Krush's clever 30. Nxd6! trapped piece combination snares a Rook if her opponent declines the pseudo-sacrifice or the Queen (as in the game) if he accepts it.

The sequence of pawn forks (double attack) which follow, and the final trapping of a Knight or Bishop after 37. d6!, enhance the entertainment value of this amusing game.

Jul-25-07  JG27Pyth: <Swing and a miss for me. I did actually look at Nxd6 several times, but Bc5 just completely eluded me.>

ditto. :(
