On setting up the board, we observe:

* We are equal on Rooks.

* We are equal on Bishops, ours the light and theirs the dark.

* We are equal on kNights.

* We both have Queens.

* We are equal on Pawns.

* We have an immediate checking opportunity with Nh6+, but it’s a kNight sac.

* We have an immediate checking opportunity with Bd5+, but it’s a Bishop sac.

* We have an immediate checking opportunity with Ne7+, forking Black’s King and Rook.
* We have an immediate forking opportunity with Nxd6.

* We face immediate checkmate on Black’s next turn with Qa2#.

* We have a Queen Rook battery on the f file, blocked by our own kNight.

* Black has a Queen Rook battery on the c file, blocked by their own kNight.

* Black has a pawn downfield on the a file.

* With 3 escape squares, but with our control of the f file, I believe there is a King Trap.

* It is our turn to move.

* The puzzle’s title is “Interception!”

* It is Wednesday.

The above observations inform potential strategies:

There is a forking opportunity initially by opening with Nxd6, forking Black’s Queen and Rook, however this is not a forcing move and so allows Qa2#. That’s a no go.

We can certainly stop the threat of immediate mate by opening with Rxc1. This most likely prompts a recapture of Qxc1+, however, awarding our opponent tempo and forcing Ka2. Black’s only follow up check would be Qc4+, forcing us to either Ka1 or Kb1. In either scenario, we’ve lost a Rook for a kNight, and we’ve more importantly lost our Queen Rook battery on the f file. This defensive strategy is a no go. We must use the tempo we have at the start of the puzzle and press our attack until we’ve either won with checkmate or decisively defeated Black’s army.

So, on to examining our immediate checking opportunities:

Opening with Nh6+ almost certainly prompts Bxh6. We’ve now both lost a kNight and opened up another escape square for Black’s King on g7.
-----We could follow with Bd5+, but this fails to Qxd5.
-----We could alternately follow with Qf7+, but this fails to Qxf7, and if we then Rxf7, we’ll lose our Rook as well to Kxf7.
-----We could alternately follow with Qf8+, but this fails to either Rxf8 or Bxf8, the latter being more likely IMHO as Black will want to keep their battery intact on the c file. 

In any scenario, opening with Nh6+ is a no go.

Opening with Ne7+ forks Black’s King and Rook, and forces Kh8, as we now own the f file, and our kNight cannot be captured.
-----We can follow with Nxc8, winning Black’s Rook, however this is not a forcing move and so allows Qa2#, losing us the game.
-----We can alternately follow with Qf8+, but this fails to either Rxf8 or Bxf8, and if we then follow with Rxf8+, this fails to whichever capture Black didn’t use first. That’s a no go.
-----We can alternately follow with Bd5, threatening Black’s Queen, and taking control of the light diagonal culminating in a2, thereby eliminating the threat of immediate mate, as our Bishop is now protected by our kNight. This forces Black’s Queen off of the diagonal, but it also loses us tempo. Black can no longer mate us immediately, but still has checking options.
-----They can respond with Nb3+, forcing either Ka2 or Kb1.
----------If Ka2, they can now Nc1++ forcing Kb1 or Ka1 and could continue this attack pattern to draw by 3 fold repetition. That’s a no go for a puzzle, although unlikely in a game. But this is a puzzle so no go it is indeed. 

Opening with Bd5+ forks Black’s King and Queen along the light diagonal culminating in a2, and almost certainly prompts Qxd5. Our threat is eliminated, our kNight is now targeted, and we’ve done nothing to prevent Qa2# on Black’s next play. We can now however play Ne6+, and we fork Black’s King, Queen and Rook. A kNight check cannot be blocked, and in this position our kNight cannot be captured, so this forces a King move. With our control of the f file, Black’s only response option is Kh8.
-----We can now Nxd5, winning Black’s Queen, and a decisive material advantage. That’s a material gain solution if I’ve ever seen one. I dig it.

Ok, it’s a plan – but how could it fail?

Well we’ve opened with a forcing fork, but Black does not have to cooperate with our plan by capturing with their Queen. However their Queen is their only piece that can capture, so deciding to not capture means moving their King. Their options are either Kf8 or Kh8. In either scenario we then Bxc4, winning their Queen anyway. Their response would likely be Rxc4, recapturing our Bishop, however our material advantage is still quite decisive. The threat of mate is relieved and we can press our attack. Nxd6 threatens Black’s Rook, and additionally covers c8, preventing Black’s Rook from returning to the back rank.
-----Had Black played Kf8, this would also be a discovered check on the f file, forcing Kg8 or Ke7.
----------If Kg8, we can Nxc4, winning Black’s Rook and increasing our material advantage.
----------If Kg8, we could alternately press our attack with Qf7+, forcing Kh8.
---------------We can follow with Nf5, threatening # on our next play with Qxg7#. If their Bishop stays put we #, and if their Bishop moves, where ever he moves we can capture, increasing our material advantage and closing our mating net.
--------------------If Bh6, we Nxh6, preparing for Qg8#, or if necessary Qf6#, depending on Black’s Rook.
--------------------If Bf8, we Qxb8#.
--------------------If Bf6, we Qxb6+, forcing Kg8, and then Qg7#.
--------------------If Be5, we dxe5, preparing for either Qf8# or Qf6# depending on Black’s Rook.
--------------------If Bxd4, we Nxd4, preparing for Qf8#.
-------------------------If Rc8, we can Nf5, preparing for Qg7#.
------------------------------If Rg8, we can Nh6, preparing for Qxg8#. And nothing Black can do can stop either this or Qf8#, depending on the position of Black’s Rook.
----------If Ke7, we can Nxc4, winning Black’s Rook. From here Black cannot return to the f file, their kNight is deep in our territory and under threat of capture, and their Bishop is but a simple Queen fork away from capture. The game is ours.

Ok, but is there a BETTER PLAN?

Not today. Now let’s go get that Queen!

Confident in my plan, I set the board aside and engage with the puzzle online.

Bd5+ is correct, and Black chooses to capture with Qxd5.

Ne7+ is correct, and Black is forced to Kh8.

Nxd5 is correct, and the PUZZLE IS SOLVED!

A wonderful Wednesday puzzle from a mystery puzzler.

Have a great day everyone.
