| Nov-07-11 | | rhickma4: Slightly harder than a typical Monday.
I saw yesterday solution quicker.
23...Re1+ wins the Q for a R
If 24.Rxe1 then 24...Qxd3
If 24.Kh2 or 24.Nf1, then 24...Qxd3 25.Rxd3 Rxa1 |

| Nov-07-11 | | jackalope: <Robespierre> - as a fellow "practiced novice", I've wondered the same thing. I'm new to this site and find that the more puzzles I do the quicker I see solutions - call it "practiced pattern recognition." I've come to believe that the true chess prodigies have extraordinary pattern recognition. My guess is there are likely many studies in this field although perhaps not as it applies to chess. AI and intelligence work (code breaking, aerial analysis, etc.) are certainly applications where pattern recognition is studied intently. |

| Nov-07-11 | | syracrophy: After 23.h3?? comes 23...♖e1+!! A classic theme of decoy by sacrifice!
click for larger viewBoth replies result in a whole ♖ down for white (if you count a ♖ for a ♕ exchange): <a)> 24.♔h2 (♘f1) ♕xd3 25.♖xd3 ♖xa1  <b)> 24.♖xe1 ♕xd3 <<<>><♕♔♕>> Just as in the games:

| Nov-07-11 | | M.Hassan: "Very easy" Black to play 23...?
23............Re1+
24.Rxe1 Qxd3
And White Queen is lost.
If declined taking the Rook:
23.........Re1+
24.Kh2 Qxd3
25.Rxd3 Rxa1
And Blck is a Rook ahead |
|
| Nov-07-11 | | mig55: Indeed, dzechiel, I had the same toughts, I found it not so easy as a normal Monday puzzle. |
|
| Nov-07-11 | | stacase: I found it by trial and error, look at each possible move to see what happens. When I got to the Rook says check, it was OH! My long time noon chess partner always hated it when I said Oh! |
|
| Nov-07-11 | | mohannagappan: 23. ...Re1+ |
|
| Nov-07-11 | | morfishine: <23...Re1+> Curiously, White's rook on <d1> is overloaded on this seemingly secure spot; The Back-rank shot by Black's rook reveals its inability to satisfactorily cover both <d3> & <a1> |
|
| Nov-07-11 | | gofer: A "deflection" on a Monday?! Surely this is not so "Very Easy" as our normal Monday-fare... <23 ... Re1+>
<24 Kh2 Qxd3>
<25 Rxd3 Rxa1>
White is down a whole rook and the position looks pretty hopeless as black's rook have open files
to play on...
26 a3 a4 and white is already in trouble...
26 Ra3 Rb1 27 Rb3 a4 (b3 and the rook is trapped) 28 Rb7 Be6 and white's king side pawns are looking
in trouble!
Time to check... |

| Nov-07-11 | | cocker: Wonderful way to win material and the game. |
|
| Nov-07-11 | | ChessNewbie55: Appropriately a Monday puzzle....you don't even need to analyze this...ho hum |
|
| Nov-07-11 | | Ratt Boy: I think White wanted to regroup with ♕f3 and ♖e1. Of course, he couldn't do that immediately, because of 23...♗g4. So he blundered with 23.h3?? It kinda looks like he has to play 23.♕xg6, though that reconnects Black's ♙s and, with a protected passed pawn, Black looks better. Maybe 23.♔f1 would hold, but I don't like the look of it. |

 | | Phony Benoni: <Robespierre> <jackalope> In the area of chess thinking, I've heard good things about Adrianus Dingeman De Groot <Thought and Choice and Chess>, but I've never read it myself. Warning: it's scholarly, not popular. |
|
| Nov-07-11 | | zb2cr: This was a little different from the typical Monday fare. Still simple to see. Well done, <chessgames.com>! |
|
| Nov-07-11 | | dakgootje: Regarding the decision making in chess, a fair amount of research has been done. Haven't read it myself - but I suppose 'Mechanisms and Neural Basis of Object and Pattern Recognition:
A Study with Chess Experts' might be interesting: http://www.smivision.com/fileadmin/... or perhaps: Visualization, pattern recognition, and forward search:
effects of playing speed and sight of the position on grandmaster chess errors: http://wjh-www.harvard.edu/~cfc/Cha... <Either way>: both have a lot of reference for further reading. I'd recommend skipping most of the numerical results - and just trust whatever conclusions they make ;) |

 | | agb2002: Black has the bishop pair for a bishop and a knight. The rook on d1 defends the queen. Therefore, 23... Re1+: A) 24.Rxe1 Qxd3 - + [Q+B vs R+N].
B) 24.Kh2 (or 24.Nf1) 24... Qxd3 25.Rxd3 Rxa1 - + [R+B vs N]. |
|
| Nov-07-11 | | kevin86: Pure robbery by black!
23...♖e1+ if ♖xe1 ♕xd3 steals a queen for a rook.
or 24 ♘f1 ♕xd3 25 ♖xd3 ♖xa1 steals the rook while he's sleeping. |
|
| Nov-07-11 | | squaresquat: PIECES ARE NEVER STOLEN
The Queen just goes back in the bag.
Poker there is theft,deceit.It's poker
that apes war; Chess is pure business. |

 | | chrisowen: Prosecution state h3 the crime
Defence state qg6 that prime
Case in point Re1 you see
Game in order resign Vitaly
Rook file it drop success at hand
Rook hanker over oh no queen hang
Next time ill grab that pesky fly.
Head for the bar inquest from over?
Head for the bar
All far too sober! |
|
| Nov-07-11 | | hap: <Robespierre> Regarding neuroscience and chess, see "The Expert Mind" in Scientific American, July 14, 2006. Just google "chess 'expert mind'" and it will come right up. |
|
| Nov-07-11 | | sevenseaman: Very nice <chrisowen> |
|
| Nov-07-11 | | Sularus: POTD: 23. ... ?
Easy
white's rook is overburdened.
23. ... Re1+ should do it |
|
| Nov-07-11 | | stst: Not really that "easy"
see right-the-way either QxQ or Re1, but neither produces overwhelming superiority for Black.
If ..... Re1, Kh2 QxQ, RxR is exchange Q for 2 R's - maybe that what's considered "easy"?
some more moves to go for Black to claim the game. |
|
| Nov-07-11 | | Nullifidian: I agree with those who say this isn't really easy. On Mondays, I look for mates, not just the advantage. 23... ♖e1+ attacks White's overburdened rook. If 24. ♔h2, then 24... ♕xd3 25. ♖xd3 ♖xa1. White's best response may be to simply go for a direct 24. ♖xe1, leaving Black with a queen and a rook vs. two rooks. |
