|
| Mar-21-23 | | Mayankk: Black has a pesky Knight at f4, guarding many key squares. So take it out by 28 R1xf4. Ah, that also opens the d5 square to skewer the Black Queen versus its King. So 28 R1xf4 exf4 29 Rd5. Time to resign for Black. |
|
| Mar-21-23 | | Brenin: 26 ... Ne2+ and only then 27 ... f6, followed by Ng3, would have kept Black in the game. 27 ... Kd8 was a horrible blunder, but Black was probably lost by then. |
|
| Mar-21-23 | | jrredfield: I knew right away that White would take the N with a rook, but which one? I eventually saw that with 28 R1xf4 Black either accepts the sac and loses the Q to a pin or Black loses the N without compensation. Also winning but not as easily is 28 Qg4. If White captures the Black N with the other rook (28 R5xf4), he will still have a bit of an advantage, but there are a few better moves for White. |
|
| Mar-21-23 | | King.Arthur.Brazil: It is really easy: 28. R1xf4 exf4 29. Rd5 Qxd5 30. Bxd5... If Kc8 29. Rxf6 Rxf6 30. Rxf6 Kb8 31. Be6 Qe7 32. Qf3. The Black have not much to do. |
|
| Mar-21-23 | | Mayankk: Does the exchange sac work on the 26th move as well ? 25 ... Nf4 26 R1xf4 exf4 27 Rxf4. Now Black has 3 isolated and weak pawns - f7, h4 and h6. The h4 pawn should fall immediately and the other two possibly after a few moves. The White light-squared Bishop has an excellent outpost at d5 and is probably worth a Rook. I think I would have sacrificed the Rook on the 26th move itself and then grabbed those free pawns. |
|
| Mar-21-23 | | mel gibson: I don't think it's that easy because Black doesn't have to accept the Rook.
However I checked with SF and if he doesn't he still loses.
How? -
swap off the pieces - be a piece up and
take the Black pawns on the h file then push the White pawns to victory.Stockfish 15 says:

| Mar-21-23 | | FM David H. Levin: <Brenin: 26 ... Ne2+ and only then 27 ... f6, followed by Ng3, would have kept Black in the game.> On 26...Ne2+, White seems to have 27. Kf2 Ng3 28. Rxe5+ Kf6 29. Rd5, gaining time for moving the other rook out of harm's way. Although not as decisive as the game continuation, it nonetheless seems lost for Black. |
|
| Mar-21-23 | | geeker: 28. Rxf4 exf4 29. Rd5, winning the Q, was the first candidate variation I considered, and stopped there.
Of more interest, I couldn't resist clicking on the Black player, Robert Bator. Fortunately he is (was?) an IM, so can be referred to as (Int'l.) Master Bator. ;-) |
|
| Mar-21-23 | | Refused: 28.R1xf4 1-0
black can't recapture on f4 because of 28...exf4 29.Rd5 and playing on a piece down is a waste of everyone's time. |

 | | perfidious: This might even have been a Monday POTD; definitely borderline for Tuesday honours, as Black is quite lost in the game continuation. |
|
| Mar-21-23 | | stacase: Black's Queen is sitting in front of his King. How can I take advantage of that? <perfidious: ...Black is quite lost in the game continuation.> One of those little aphorisms when you post says: "The hardest game to win is the won game" |

 | | agb2002: White has a bishop for a knight.
The alignment of Black's royal family on the d-file leads to 28.R1xf4, winning decisive material (28... exf4 29.Rd5). |
|
| Mar-21-23 | | Cheapo by the Dozen: Nice easy Tuesday: Look for a mating theme, see that there is none, then immediately find the path to material gain. |
|
| Mar-21-23 | | saturn2: For a monday my 30 seconds to solve it were too long. |
|
| Mar-21-23 | | TheaN: This was surprisingly easy: the knight jumps out the moment you see the position, any Rxf4 is already good because it takes Black's best piece and turns the bishop into the best piece OTB. The fact that after <28.R1xf4 +-> Black can't even take back because of 28....exf4 29.Rd5 +- is icing on the cake. <Mayankk: Does the exchange sac work on the 26th move as well ? 25 ... Nf4 26 R1xf4 exf4 27 Rxf4.> Interestingly, SF gives an intermezzo, but otherwise the best idea: 26.Bb5! attacking the queen, after 26....Qd8 (taking the rook is not enough) 27.R1xf4 exf4 28.e5! +- cementing the position, 28....a6 may be the only try but after 29.Rd6! axb5 30.Rxd8 Rxd8 31.Qxb5 +- White's queen is dominating. Directly 26.R1xf4?! is a bit risky at +2.3: 26....exf4 27.e5! still, but now 27....Rc6 28.Rxf4 f6! ± and there is some (minimal) counterplay. |

 | | HeMateMe: Good win; I'd say Hector was a master-Bator. |
|
| Mar-21-23 | | Mayankk: Thanks <Thean>. 26 Bb5 Qd8 27 R1xf4 exf4 28 e5 etc. is a line way above my pay grade. I don't really use an engine but visually the position after 26 R1xf4 exf4 27 Rxf4 Qd6 28 Bd5 looked tempting. The Bishop at d5 can never be chased away and will likely force a Rook exchange sac from Black, after which White should be ahead by a few pawns, given the scattered pawns of Black. |

 | | LIFE Master AJ: A nice tactic that I did not immediately see ...
as I did not have my glasses on and thus did not realize that the Black Queen and the Black King were on the same line. Hehe. |

 | | eternaloptimist: <LIFE Master AJ> I didn’t solve it immediately either but I did solve it after looking at it for a few minutes. I agree that it is a nice tactic |
|
| Mar-21-23 | | AlicesKnight: 28.R1xf4 exf4; 29.Rd5 wins Q for R; QB vs. RR should be a win if White can prevent the Rs from co-operating and the Black Ps and white squares are weak. |
