Apr-05-10  kingsindian2006: this should be called a "FAB mate"...just kidding... what a beauty of a mate!!!
Apr-06-10  larsen959: Amazing!! Great Caruana!! :-))
Apr-06-10  swordfish: The final combination is beautiful, but what about 10...0-0, which looks to the untrained eye to be castling into an attack? Gutsy play.
Apr-08-10  themindset: How can the ECO be D12 if there is no Bf5?

  Domdaniel: I'm sure Potkin had checked the obvious Queen decoys, such as 30...Qxe1 or ...Qxd4. In each case White recaptures with the Bishop - not the Queen - and is fine. But ...Qc1+! is direct, lethal, and harder to see.

Caruana had some nice tactics ready earlier in the game too. If, for example, 23.Qxd5, one line is 23... Rfd8 24.Rd4 Nb5 25.Qxb5? Qe4+! mating. 26.Rxe4 Rd1#, or 26.Qd3 Rxd4 27.Qxe4 Rd1#.

Or, back in the game, 26.Rxd5 Qg6+ 27.e4 Nxe4! is murderous.

<themindset> Sometimes I think there are more dubious ECO codes in the database than there are games ...

  sleepyirv: Monday: I see knight check, see the queen defender, must mean queen sac! Decoy allows knight mate. Pretty fun puzzle for a Monday.
Apr-12-10  azax: Very easy puzzle, but that's to be expected on a Monday. We note that the White King is stalemated, so a simple check will mate him; Nb3+ becomes obvious, but there's the problem of white's queen on d1. We must make it leave the defense of the b3 square, which can be easily done with Qc1+.
Apr-12-10  Leibnoob: Oh crap, I failed monday puzzle! What a nice surprising ending.
Apr-12-10  zooter: 30...Qc1+ 31.Qxc1 (only move) Nb3# ends the game instantly.

A gratifying finish when you notice that 30...Nb3 would be mate if not for the pesky queen

Apr-12-10  lost in space: What a nice Monday puzzle! It took me a bit longer than normally on Monday to see 30...Qc1+! 31. Qxc1 Nb3#
Apr-12-10  dzechiel: Black to move (30...?). Black is up a pawn. "Very Easy."

After a couple of false starts, I finally spotted

30...Qc1+

About as forcing as it gets.

31 Qxc1 Nb3#

Pretty and to the point.

Apr-12-10  Tubba324: Took me half a second to see it. Go me.
Apr-12-10  goldfarbdj: As usual on a Monday, I looked for the Q sac first, and Qxe1 sprang to my eye. I saw that if 31 Qxe1, Nb3 would be mate; and I saw that Qxd4 would be met by Bxd4; then I noticed that white could take on e1 with the bishop also. So I looked for a different deflection and found Qc1+.
Apr-12-10  zb2cr: Like <goldfarbj>, I initially looked to try deflecting the White Queen from the defense of b3 by 30. ... Qxe1 or 30. ... Qxd4. However, I saw that the White Bishop was able to fill a defensive role. This led to my finding 30. ... Qc1+, with forced mate.
Apr-12-10  octopus115: got it.

but also noticed (with comp help) just how bad 30 Re1 is = major blunder that leads to this quick end. 30 Rb4 and its a playable game.

Apr-12-10  Smothered Mate: seen it before
Apr-12-10  Whitehat1963: Love Mondays.
Apr-12-10  TheBish: Potkin vs F Caruana, 2010

Black to play (30...?) "Very Easy"

30...Qc1+! 31. Qxc1 Nb3#.

By the way, I played GM Fabiano Caruana in 2003 at the US Open in LA. He was only 11 and not yet a master, but he was already showing signs of future greatness. As Black, he sacrificed two pawns just to secure the f4 square for his knight, which played a key role in a winning attack!

Apr-12-10  tarek1: First thing I thought was Nb3#... but no... the queen controls the square, so how to distract the queen, at any cost ? Oh, yes <30...Qc1+ 31.Qxc1> no choice, and now <31...Nb3#>
Apr-12-10  TheaN: Monday 12 April 2010

<30....?>

Target: 0:40;000
Taken: 0:10;048

Material: Black up, ♘+♙ / ♗

Candidates: Qc1†, Nb3†, <[Qc1†]>

-ML-
For some reason I initially threw away the most obvious Queen sac in this position only to go for the finisher first, but they need to be in the right order as the Rook on e1 is skewer defending the c1 square: 30....Nb3†? 31.Qxb3 and 31....Qc1†?? 32.Rxc1 obviously, however, with the Queen covering c1:

<30....Qc1†! 31.Qxc1 Nb3‡ 0-1> it works, and let the White King be trapped completely. Good ol' Monday, I guess. Time to check how White got into this messy position actually, a pawn down and a Black attack going.

  agb2002: Black has a knight and a pawn for a bishop.

White threatens 31.Rxe3 and the pawn on d5.

Black would deliver mate with ... Nb3 if the white queen didn't control b3. Therefore, divert her with 30... Qc1+ 31.Qxc1 Nb3#.

Apr-12-10  gofer: 30 ... Qc1+ 31 Qxc1 Nb3# a nice Queen sac for a Monday...

...now that is a comforting relief, a warm fuzzy way to start the week...

Apr-12-10  Shah Mat: i've found that before i even try to solve the puzzle, i look at the whole board, where all the pieces are because if i don't i miss some bishop off on h3 or something that screws up the whole combination.

but once i saw the position the king was in, the queen sac on c1 jumped out at me as a tactic first to fork the W king and queen, and noticed the mate immediately.

let's hope the rest of the week is this easy.

Apr-12-10  LIFE Master AJ: I must admit, when I FIRST looked at the puzzle, I was stumped. However, I did my checklist, and then realized that Qc1+ was an easy win. (QXQ/c1, Nb3#)

This whole process took less than a minute, it might have even taken less than 30 seconds. (I wasn't timing myself.)
