| May-08-16 | | Razgriz: Happy Mothers Day everyone. Also, this was a confusing puzzle for a Sunday. |
|
| May-08-16 | | Dilbertarian: I fail to see how White can win after 24.♖xe6 fxe6 25.♕xe6+ ♔f8 26.♗c4 ♕xb2. |
|
| May-08-16 | | wooden nickel: Thanks <ASchultz> for the winning line i.e.
24.Rxe6 fxe6 25.Qxe6+ Kf8 26.Qd6+ Kg8 27.Rc5 Qxb2 28.Qe6+ Rf7 29.Rg5+ Kf8 30.Qd6+ Re7 31.h3

| May-08-16 | | Timi Timov: According to the mediocre engine of a chess website which I won't mention for obvious reasons, Rxe6 is not the best move. Rxe6 was the move I guessed, and judging from the description, that was the solution of the puzzle but it leads to a draw. Can someone explain me what is going on? |
|
| May-08-16 | | AlicesKnight: 24.Rxe6 fxe6; 25.Qxe6+;
Now ....Kh8 allows 26.Qh6+ Kg8 27.Bc4+ Kf8 28.Qh8+ winning back the R and keeping the attack, and 25.... Rf7 allows 26.Bc4 Raf8 27.Qg6+,but 26....Qc7 looks to hold so 26.Qg6+ perhaps and looking for Bc4 and Re1 etc... I don't know, let's look .... Oh! - well, I'm in good company, it wasn't seen OTB. |
|
| May-08-16 | | Virgil A: OTB for me likely 24.Rc2
And still lose the game! Hey that's the Viktor on the opposite end. :) |
|
| May-08-16 | | alfiere nero: I would have played Bc4 or Re5 ... way above my head these Sunday puzzles! |
|
| May-08-16 | | agb2002: The material is identical.
Black threatens c5 with pressure on g2.
The first move that comes to mind is 24.Rxe6, trying to expose the black king: A) 24... fxe6 25.Qxe6+
A.1) 25... Kh8 26.Qh6+ Kg8 (28... Rh7 29.Qxh7#) 27.Bc4+ Kf8 (27... Rf7 28.Qg8+ Kh8 -28... Kf7 29.Qxf7#- 29.Bxf7 and mate in two) 28.Qf6+ Ke8 29.Re1+ Kd7 30.Qxg7+ wins two pawns at least while keeping the attack. A.2) 25... Kf8 26.Qd6+
A.2.a) 26... Ke8 27.Re1+ and mate in two.
A.2.b) 26... Kf7 27.Bc4+ and mate in two.
A.2.c) 26... Kg8 27.Rc5
A.2.c.i) 27... Qxc5 28.Qxc5 + - [Q+2P vs 2R]. For example, 28... Rd8 28.Bc4+ Kh8 (28... Kh7 29.Qxh5#) 29.Qxh5+ Rh7 30.Qe5+ Rg7 31.g3 c5+ 32.Kg1 Rd1+ 33.Kf2 Rd2+ 34.Ke3 Rxh2 35.Qe8+ Kh7 36.Bd3+ Kh6 37.Qh8+ Rh7 38.Qxh7#. A.2.c.ii) 27... Ba6 28.Qe6+ Rf7 (28... Kf8 29.Rf5+ Rf7 30.Qxf7#; 28... Kh7 29.Rxh5#; 28... Kh8 29.Rxh5+ Rh7 30.Rxh7#) 29.Rg5+ Kf8 (29... Kh8 30.Qh6+ Rh7 31.Qxh7#) 30.Bg6 wins (30... Qc7 31.Bxf7 Qxf7 32.Rf5; 30... Rc7 31.Qf6+ Kg8 32.Bf7+ Kh7 33.Rxh5#; 30... Bc4 31.Qxc4 doesn't seem to solve anything for Black). A.2.c.iii) 27... Qc7 28.Bc4+ Kh8 (28... Kh7 29.Rxh5#; 28... Rf7 29.Qxc7 wins) 29.Rxh5+ Rh7 30.Qxc7 Rxh5 31.Qxb7 wins decisive material. A.2.d) 26... Re7 27.Rc5 looks similar to A.2.c (27... Qxc5 28.Qxc5 and 28... Re1+ is impossible). A.3) 25... Rf7 26.Bc4
A.3.a) 26... Raf8 27.Qg6+ Kh8 28.Bxf7 wins decisive material. A.3.b) 26... Qc7 27.Rd1
A.3.b.i) 27... Bc8 28.Qg6+ Kf8 29.Bxf7 looks winning (29... Qxf7 30.Rd8+ and mate next). A.3.b.ii) 27... Rd8 28.Rxd8+ Qxd8 29.Qxf7+ Kh8 30.Qxh5+ (30.Qxb7 Qd1+ 31.Bf1 Qxf1#) 30... Kg7 31.Qg5+ Qxg5 32.fxg5 + - [3P]. A.3.b.iii) 27... Kf8 28.Qh6+
A.3.b.iii.1) 28... Ke8 29.Rd6 looksvvery good for White. For example, 29... Rd8 30.Bxf7+ Qxf7 31.Qh8+ wins the queen or mates. A.3.b.iii.2) 28... Kg8 29.Rd6, threatening Rg6+, looks winning. A.3.b.iii.3) 28... Rg7 29.Qh8+ is a massacre.
A.3.b.iii.4) 28... Ke7 29.Bxf7 wins decisive material: 29... Kxf7 30.Qh7+ and 31.Qxc7. B) 24...Rd8 25.Rd6 (25.Re7 c5 26.Qxb6 Bxg2+ doesn't look very good) wins a pawn at least. For example, 25... Rxd6 26.Qxd6 c5 27.Qb8+ and mate in two. |

| May-08-16 | | Patriot: At first this did not register to me as even having a combination because the "seeds of tactical destruction" just didn't seem to be there. But then I don't claim to know all of them. My first candidate was the game move and I think it's a great practical move. Because if no seeds register you can't spend endless time searching for something that is probably not there. But I wanted to be very sure I wasn't missing something so I considered the sacrifice 24.Rxe6. It began to look better but the problem was what to do after 24...fxe6 25.Qxe6+ Kf8 26.Qd6+ Kg8? I totally missed 27.Rc5 per the computer's response, which <ASchultz> also points out. |
|
| May-08-16 | | drollere: it says "White missed 24. Rxe6!!" right there in the game log. thanks for the hint! |
|
| May-08-16 | | morfishine: Count me out: While <24.Rxe6> is really the only "insane" move in this position, I just couldn't bring myself to believe this would work out. So, I pondered awhile over <24.f5> then thought, "What the heck, the weather's too nice to be looking at this stuff" and loaded up beers and sandwiches and headed to the pool to check out the hotties <Patriot> Nice thought process ***** |
|
| May-08-16 | | Patriot: <morf> Thanks! But I like yours better!! :-) |

 | | Jimfromprovidence: Did not come close to getting this.
Looking at the comments, I also thought that after 24.Rxe6 fxe6 25.Qxe6+ Kf8 26.Qd6+ Kg8 27.Rc5 Qxb2, below, it's a draw. Black has forced mate threats at g2 and a1 that look daunting. 
click for larger viewBut after 28.Qe6+ Rf7 (gets the Rook off of the g file, taking away ...Qxg2#) 29.Rg5+ Kf8 30.Qd6+ (stops ...Qxc1+ Kh2 Qxf4+) Re7 31.h3, white is indeed winning.

 | | Willber G: I would have played 24.Re5 |
|
| May-08-16 | | scholes: if Black defends like stockfish, white recovers his material after 15 moves. Insane i would say |
|
| May-08-16 | | morfishine: <Jimfromprovidence> I always enjoy your posts, but I'd stop short calling this a "Great Puzzle" It's more of an "Enigma wrapped in a Riddle"

| May-08-16 | | whiteshark: < mel gibson: It says in the downloaded script.
"white missed 24. Rxe6! " I saw that but when I tried it on the computer it was still a draw.> Horizon effects and/or rigid tree cut-off and/or standard draw setup. #Accompany the space bar |
|
| May-08-16 | | stst: The Black K is essentially trapped. Not difficult, but just a long process.
To start the ball rolling, need a R-sac, else soft moves like advancing the P may also work.
24.Rxe6 fxe6
25.Qxe6+

25.............Kh8
26.Qh6+ Kg8
27.Bc4+ Kf8
28.Qh8+ Ke7
29.Qxg7+ Kd8

could miss something shorter in between, but essentially the Black Q does not have any chance for action. Not too a beautiful game. |

| May-08-16 | | stst: The first move Rxe6 echoes the lightened comment "White misses 24.Rxe6!!"
and the comment echoes many that this

 | | An Englishman: Good Evening: Found the winning move and a huge series of checks that had to lead to at least a draw, congratulated myself for solving a Sunday puzzle and going 7/7 for the week--and then saw that White didn't play the move. I thought this was a classic CG practical joke--Krogius shunned 24.Rxe6 because it was unsound--but <RandomVisitor> has done very good work in demonstrating that it wins. But when you realize that some winning lines exceed 30 moves (!), one can understand Krogius' reluctance to venture upon this sacrifice in a real game. |
|
| May-09-16 | | AvidChessMan: Knowing that the game ends in a draw, I was looking for the more quiet move. I took notice the positions of both black and white bishops and thought about protecting the white king. My last thought, before clicking on the next move was Be4. I did not even consider Rxe6. |
