  chrisowen: Ala 'no IM' Bennett plays right.. Qd1+ then Rd4 stages a comeback to enjoy. A bodge of acting out Qc4 critically receives poetic justice. This is not unforseeable that soins intensifs should've been taken when rooks dive into the fray. Perhaps it was the habit of art.

  kevin86: This was so easy,I stumbled over it. I saw the check and then saw the fork.

The intermezzo queen check allowed the queen to coyly escape from the exchange by her equal.

Same here! I'll bet you considered Rd2 Qxc4 Rxd8 Qc5 and trading things off with Rxf8+ Qxf8 Bxf8 Kxf8. I did and then realized it was black's move! However I saw no advantage in that line for white.

It took me too long (several minutes) to see the simple fork 31...Qd1+ 32.Kh2 Rd4.

Some of you mention a counter-attack with either 33.Rc1 or 33.Rd2. This is a "counting" problem in which black wins a piece either way: 33.Rc1 Rxc4 34.Rxd1 Rxf4 OR 33.Rd2 Rxc4 34.Rxd1 Rxf4.

Feb-09-10  scormus: <zb2cr> glad I'm not the only one that does that. These positions can very really "insane" to solve when youre trying to win for the wrong side!

  Jimfromprovidence: The puzzle needs a bit more time to solve than one would think.

Beside looking at 33 Rc1 as a defense, 33 Qe2 needs attention as well.

Feb-09-10  YouRang: Quite easy since 31...Qd1+ is the most obvious move to consider and 32.Kh2 is forced.

Just spend a moment at that position looking for tactics, and you can hardly miss the rook fork that wins a piece.

Feb-09-10  Uncle Mark: got it, even if took more than 2 minutes.....
Feb-09-10  Kasputin: Suffering from an attack of puzzle-itis. Puzzle-itis is a condition in which one looks at possible moves that wouldn't even be considered in a real OTB situation. It also involves overlooking fairly obvious moves that would be considered far more quickly in a real situation.

It is a rare condition because most often, when faced with a puzzle, knowing it is a puzzle has an obvious and immediate advantage. But with puzzle-itis the reverse is the case - knowing it is a puzzle can lead to frustration, head scratching, or in extreme cases turning off computers or throwing chess boards and pieces across the room.

31...Qd1+ followed by 32...Rd5 and white cannot protect the bishop on f4. Why did this take so long to see?

Feb-09-10  DarthStapler: Got it
Feb-09-10  Kasputin: <YouRang> clearly you've built up immunity!
Feb-09-10  MaczynskiPratten: The European Team Championship seems to have been quite a performance by Ala/Alan Bennett. From the Chessgames listing, he seems to have scored 3/7 against players who generally outranked him by 200-400 grading points.
Feb-09-10  Marmot PFL: <33 Qe2 needs attention as well> How does this guard the Bf4?
Feb-09-10  cyclon: 31. -Qd1+ 32.Kh2 (Qf1?? Qxc2) -Rd4 wins a Bishop, f.e. 33.Qxc6 Rxf4 34.Re2 Bd6 should be "cufflinks".

  Once: <zooter: I notice that everybody points out the counter attack 33.Rc1 as a reasonable defence. But I have to wonder why>

33. Rc1 loses. But it doesn't lose as fast as "32. Kh2 and resigns". I don't think that anyone is saying that 33. Rc1 is a reasonable defence, but it does need to be analysed accurately (as you have done).

<goodevans: Interesting today how many typos there are in the kibizing>

Yup - me too, typing Rd1+ instead of Qd1+ as the first move. We've also had Qd8+ instead of Qd1+ and Rd5 instead of Rd4. You may have a point about this being partly due to the fact that it is black to move. My typo is more because I was rushing to get my kibbitz off before going to work.

Feb-09-10  TheBish: D Bojkov vs Ala Bennett, 2009

Black to play (31...?) "Easy"

Black wins a piece with 31...Qd1+ 32. Kh2 Rd4.

Feb-09-10  kingsindian2006: <jimfromprovidence> both your examples of defense lose a piece still...

  patzer2: For today's Tuesday puzzle solution, 31...Qd1+! 32. Kh2 Rd4 combines the clearance, deflection and double attack (Rook Fork) tactics to win a decisive piece.

  Jimfromprovidence: <Marmot PFL><How does this guard the Bf4?> It doesn't.

<kingsindian2006> <both your examples of defense lose a piece still>. I know.

With 33 Qe2, I was just trying to make the small point of black needing to get the move order correctly in case white tried something unexpected.

Feb-09-10  WhiteRook48: 31...Qd1+ 32 Kh2 Rd4
33 Rc1 Rxc4 34 Rxd1 Rxf4
Feb-09-10  turbo231: I'm still playing mondays rook vs knight end game against rybka so far the best i can do is a draw. I played the same game against crafty, a piece of cake, chessmaster 9000 no problem. But this rybka is something else. My rybka has the 5 men end game tablebases, i have the proper egbbdll.dll and egbbso.so files for it so it's working. My GUI shows rybka taking over a million end game tablebase hits. I set the the level at 20 moves in 25 minutes repeating. I think i can beat it, i'm not going to stop until i do, someone please pray for me.
Feb-09-10  kingsindian2006: <turbo231> turbo i will take time off praying to the "Poker Gods" to pray for you to beat rybka....lol
Feb-09-10  Formula7: Okay, 31...Qd1+ 32.Kh2 Rd4 wins a bishop (if 33.Rc1 then Rxc4 34.Rxd1 Rxf4)

Time to check.
