  Whitehat1963: Saw the basic and immediate idea, but I didnít work it out even close to all the way.

  Once: Aha! I've found the rook-winning skewer!

In human mode, the line I struggled with was this one:

24. Nd6 Rd5 25. Rxe7 Qd3+ 26. Qxd3 Rxd3 27. Nf5 g6

At the limit of my calculating range, I couldn't see how white could rescue both of his attacked pieces.

With Fritzie turned on and a diagram in front of me, I spotted 28. Rxh7. Now if 28... gf 29. Rh8+ wins the a8 rook with our signature tactic of the week.And if 28...Kg8 29. Rg7+ followed by Rxg6 and the knight is saved.

It's another of those puzzles where the first few moves are simple but the follow-up is a little more complicated than it first looks.

  takchess: I saw the knight move and blacks forced rook move response. Trouble was I felt there was a knight fork but didnt quite see how it worked. Also investigated 1.Rd3 but that lead nowhere.
Jun-14-18  Mayankk: I was distracted by the potential strength of 24 Rxe7 Kxe7 25 Qxc6 threatening both Rooks as well as Qd6+.

Must be of no use as no one even mentioned it.

  OhioChessFan: <Maynkk> I had a look at that also, not sure why I didn't go for the Knight move first, but Rxe7 in the middle of the board seemed like a good starting point. The big problem with the line you suggested is giving up the d3 square.

24. Rxe7 Kxe7 25. Qxc6 Qd3+ 24. Kb2 Qd5 defends both Rooks.

<24. Ka1> Rd8 and Black just piles up on the d file.

In both cases, the Rooks are defended, Black remains the exchange up, and the White King is in real trouble.

(25...K:e7 26.Nf5+ )
(25...R:d6 Qf7# )

26.Q:d3 R:d3 27.Nf5

  ChessHigherCat: Just to bring my notation into line with other sentient beings: 24. Nd6 threatening the rook. If Bxd6?? <Qf7#> monsoons on black's parade.

So only moof: 24... Rd5 blocking the mating diagonal

25. Rxe7 Kxe7 (...Rxd6??? 26. Qf7#) 26. Nf5+ with a royal fork

  ChessHigherCat: Hi <once>, <ocf> and <malt>

With the painful clarity of the light of day, I see the possibility of forcing the queen trade with 25..Qd3+

Does this work?
25...Qd3+ 26. Qxd3 Rxd3 27. Nf5 g6 28. Rxh7 Kg8 29. Rg7+ Kf8 or Kh8 30. Rxg6

Now everything's covered and white's a piece up

  Sally Simpson: A wonderful example showing the strength of a Rook on the 7th rank.
Jun-14-18  mel gibson: I saw another solution -24.Qxc6
I checked it on Stockfish 9 & it works.
The White Queen wins a pawn & a Rook straight away. I also let the computer play on at 6 seconds each side per move & White quickly demolished Black.

24.Qxc6

Yes - takes a pawn, attacks 2 Rooks & defends the Knight. Why didn't everyone see that like I did?

  Marmot PFL: First three moves are easy but black keeps fighting and the finish has to be accurate from white.

  Carlos0012358: <agb2002> your line C) works well through 27.Nf5, but from there I would have played 27.....a5, 28.Rxg7 axb4, 29.Rxh7 Kg8, 30.Rb7 Rd2, 31.Nh6+ Kh8, 32.Ng4 Raxa2...... Attacking the white king with both rooks.
Let me know what you think.

  Jimfromprovidence: <wtpy> <Nice combo which I saw through Rg7+. Playing through the game I was stumped briefly by 27.. Kh8 but then saw Rg3 which allowed Gawain to consolidate his gains.>

If 27...Kh8, 28 Rg3 below is better than you realized.

It wins the queen because of the threat 29 Nf7#

  morfishine: <mel gibson...Why didn't everyone see that like I did?> Perhaps the move <24.Nd6> was first seen by most. This happens often in these positional problems emanating from real games vs a puzzle created from scratch
Jun-14-18  wayndom: From the position shown, doesn't 24.Qe6 end the game faster? 24...Re8, 25.Nd6

Am I missing something here?

  morfishine: <wayndom> Awkward is <24...Qxe4+> 25.Kb2 Rxb4+ 26.cxb4 Qxb4+
Jun-14-18  njchess: 24. ♘d6! ♖e5 ▢ 25. ♖xe7! +- Black has few if any good moves at this point. Perhaps 25. ... ♕d3+, forcing the queen trade, is the best of the worst. More likely, he should just resign.

<mel gibson: Yes - takes a pawn, attacks 2 Rooks & defends the Knight. Why didn't everyone see that like I did?>

24...Re8 25. Qxb5 Qxe4+ 26. Qd3 Qxg2 and Black still has a pulse.

24...Rab8 and White has a lot of worries of a perpetual.

24...Rbb8 and both Rooks are defended, and Black intends Rc8. White is much better, but I don't see this as clearly winning as the game line.

Anyway, that's 3 lines for White to think over and none of them seem as clear cut as the game line.

Jun-14-18  et1: All the combination looks like magic In the final position white threatens Kf7 "! with fork and winning the Rook or mating. Amazing !
Jun-15-18  mel gibson: < I don't see this as clearly winning as the game line.>

True - but it's still a solution.

The possibility 27... a5 didn't occur to me but in your line the natural 33.Rxb4 leaves Black a knight down without compensation. For example, 33... Rxg2 34.Nxf6 Rxh2 (to prevent h4-5-6) 35.Rh4+ Rxh4 36.Rxh4+ Kg7 37.Nh5+ Kg6 38.Kxa2, etc.
