Let me tell you that there is an easier mate in two, Re1+, QxE1, QxE1#

Re1+?? Qxe1 Qxe1+??? Nxe1!
Nice one!
Don't think it is a Novotny though. The Rook move interrupts a Queen play line but not a "Knight play line" as Knights do not move along lines. If the Knight were a Nightrider (Fairy piece based on multiple Knight moves) then the rook move might count as Novotny but only if black takes advantage of the interruption of the Nightrider line after the Queen captures the Rook!

Really? Oooh I thought that, since there was chekcmate on with Qf1/Qg1 if the knight captured the rook interfering with the queen, it could have been considered a Novotny... So it can be called like so only if there are multiple interferences, not if the interference occurs after the capture too?

I'm thinking Bg4.
If Qg1 then Re1 wins.... KnightxR = QxQ#
Ph3 to create an escape square also doesn't work because BxK and it is mate in another move or two or at least loss of so much material it is over anyway.

No because after Qg1 Re1 there’s Qxe1. By the way, Bg4 is really interesting, and after Qg1 you can also play Qxf3!!

Right! I thought it was there but didn't have a chance to play it out fully.

Look up and study the examples on Wikipedia. A Novotny move interrupts 2 defensive lines simultaneously and the opponent can only reopen either of them by his capture choice. In your puzzle, Qxe1 reopens the queen line and the defense of square g1 but Nxe1 does not reopen a knight line, simply because knight lines do not exist. Just having 2 different checkmates is not enough for a Novotny.
Btw, I just had a nice idea for a Novotny composition if you are interested. Suppose white has 2 ways to make a Novotny move to the same square, like "d4" and "Nd4". Both seem to work but when you look closer you'll find that d4? fails to an en passant capture. Why is that? Simply because "en passant" is the only way in chess to reopen the 2 lines of defense simultaneously after a Novotny move! So it fails and the correct solution is Nd4! Just an idea and someone might have thought of it before!

So it's interference in a strict sense, there can't be other tactic themes involved. Thank you, I saw an example of Novotny that may have confused me. By the way, I'll work on it and I'll send you the position
In this position that almost occurred me in a game (I played the same moves anyway, even if the first one was losing) black has a beautiful mate. Difficulty: medium. Small hint: this is a very rare example of Novotny tactic during a game
