 | | agb2002: Black has a knight for a bishop.
Black can expose the white king with 25... Rxg3, threatening Rg1# and taking advantage of the pinned rook: A) 26.fxg3 Rf8+ 27.Rf3 (27.Bf2 Qh1+ 28.Ke2 Rxf2+ 29.Ke3 Qf3#) 27... Rxf3+ wins. B) 26.Rxg3 Qxc2 27.Rdd3 Nf4 wins decisive material. |
|
| Jan-28-21 | | Brenin: Instead of 25 Rad1, White needed to play 25 Rc3, losing a P to 25 ... Rxf2+ 26 Bxf2 Qh1+ 27 Ke2 Qxa1, but surviving. |
|
| Jan-28-21 | | Walter Glattke: 26.f3 Rg1# |
|
| Jan-28-21 | | Stachys: I don't see any means of white avoiding mate with the following line by black: 25...Rxf2+ 26. Bxf2 Rf8 27. Rd4 Qh1+ 28. Ke2 Rxf2+ 29. Kd3 Qf3# White would have one "free turn" in which to do anything one might wish--there just aren't any good options at that point. |
|
| Jan-28-21 | | eyalbd: Many moves win.
I went for ♖e3 with the same idea. If ♖x♖ then ♕x♕ -+ and if fxe3 then ♕h1 with mate. |

| Jan-28-21 | | burleyman2: Does W have any way of defending himself after 25 ... R8f8 ? |

 | | rodchuck: <eyalbd> Yes, I went with 25...Re3 too, but on reflection, I don't think that after winning the queen, it is as conclusive as the game continuation; 27. Rd2 and white still has some counterplay, as the pawn on e7 seems lost after the queen moves. (25...Re3 26.Rxe3 Qxc2. 27.Rd2 Qf5 (supporting the knight) 28. Rxe7 with Rde2 coming up. With 25...Rg3, e7 is no longer threatened after 27...Qf5 |
|
| Jan-28-21 | | Cheapo by the Dozen: I went with the game line all the way. I first spent some time looking at 26 ... Rf8+, which also wins thumpingly, but failed to see the quick mate that refutes 27 Bf2. |
|
| Jan-28-21 | | Cheapo by the Dozen: Why did White refuse the gambit pawn at c6 and then play Nc6 a move later when the pawn was no longer there? |
|
| Jan-28-21 | | malt: 25...R:g3 26.fg3
(26.R:g3 Q:c2 )
26...Qh1+ 27.Ke2 Qg2+ 28.Ke3 Q:c2 |
|
| Jan-28-21 | | AlicesKnight: I went with the game line, partly thinking that 25.... Rxf2+ could be met by Qxf2 conceding Q for R and minor piece and prolonging things (without much hope....). |
|
| Jan-28-21 | | njchess: <Cheapo by the Dozen> With respect to the c6 pawn capture, I think the loss of tempi and the loss of active pieces are the main reason. While White grabs a pawn, he loses tempi since his Queen must then retreat. Black must already move his rook off of a8 to avoid White's bishop, by capturing you remove the threat of the bishop and give incentive for Black to move the rook (i.e. to threaten the White's queen). The other reason is until White's knight is forced off of d4, ♘e6 is a still a threat. By capturing, you remove these possible threats and simplify the position, without any real advantage. Ironically, after 16. ... ♕e6 and 17. ... ♘e4 Black trades away his diagonal Bishop, but ends up with his knight well placed on e4 as compensation. All in all, nice play from Marin. |
|
| Jan-28-21 | | Cellist: I also went for 25. ... Re3, which wins very clearly, as others have pointed out and as SF confirms (-6.76). Actually, the natural Rbf8 wins even more overwhelmingly (I considered it and would likely have played it over the board but dismissed it as a solution to a problem). So we have three valid solutions. |

| Jan-28-21 | | 1g1yy: I missed it. I found a win but it took longer. I guess that's the difference between masters and patzers. lol. In fairness, I was looking for a 2 or 3 move mating combination but it was farther out than that. I'm new to the site and I love these daily puzzles. |

| | chrisowen: No but catch a glimpse g3 no? |
|
| Jan-28-21 | | landshark: The simple 25.... Rbf8 also leaves White completely busted. Truth is, it's a very easy position for Black to play and win. |

| Jan-28-21 | | King.Arthur.Brazil: Sincerely, I saw the trump of: 26. ♖xg3 ♕xc2 27. ♖d2 ♕f5 with a ♕ by an ♖. Obviously, that any other answer like 26. ♖e3 ♖g1+ 27. ♔e2 ♕xc2+ (If 28. ♖d2 ♕c1 or 28. ♔f3 ♕xd1+ or 28. ♗d2 ♕xd1+ and white already lost the ♕. However, my answer for was 26...♖f8+ because of the line: 27. ♗f2 ♕h1+ 28. ♔e2 ♖xf2+ 29. ♔e3 ♕f3# which seemed to be forced. Then, it becomes to me that White would have to give up from his ♕ by 27. ♕f2 ♕h1+ 28. ♔e2 ♘xf2 29. ♗xf2. In such position, 29. ♕e4+ 30. ♗e3 ♕f3+ 31. ♔e1 ♕xg3+ 32. ♔d2 ♕g2+ 33. ♔c1 ♕xa2 or ♕g2 30. ♖f1 ♕e4+ 31. ♖e3 ♕c2+ 32. ♔e1 ♕xa2 white will win, but maybe too slow. I didn't realize that White could not answer 26...♕h1+ 27. ♔e2 ♕g2+ with 28. ♗f2?? because of simply ♕xf2#. So, by moving 28. ♔e3 ♕xc2 the ♕ is lost and Black keeps his ♘ for a while. Maybe, 29.♖3-d2 ♕f5 30. ♖d5 e5 31. ♖xd6 ♖f8 32. ♖6d5 ♕f3+ 33. ♔d2 ♘f2 and White will lose more material soon. |

 | | gawain: Black has many ways to win. I was focused on ...Rxf2+ with the intention to bring the other rook to f8 but the prettiest combination is probably as in the game. If White cooperates for one more move we have a lovely sideways epaulet mate.

| Jan-28-21 | | TheaN: I had a look at this Thursday and didn't realize it was <this> simple. <25....Rxg3> and it's obvious Black's forcefully destroying the castle. <26.fxg3> and both Rf8+ and Qh1+ win (I saw Rf8+ with disaster). 26.Rxg3 Qxc2 27.Rd2 Qf4 -+ isn't better. The only pitfall Black should avoid is 26....Rf8+ 27.Bxf2 Rxf2+? 28.Qxf2 with full equality; 27....Qh1+ 28.Ke2 Rxf2+ 29.Ke3 Qf3# might be slightly better. |

| Jan-28-21 | | mel gibson: I should have looked longer
as I didn't see it yet it's so simple.
