I tried it by myself but it looked hard for my chess ability

so I tried to solve it with engines but they can't solve it

after 23 plies
white is still losing by -3.0 points or so

Yes Engines Cannot solve it :) I think not even with very long analyze

I give it a little more time for more members to think about this beautiful puzzle and even more beautiful solution. I answer it in the next days if nobody is able to find the solution

Nice position. I think Nf7 is the first move!?

Let's run with that... Nf7, Re8. If white can force a win it doesn't matter what black responds with. We're not given any info on how many moves until the desired outcome is achieved and if that is checkmate or not, so it's very vague.

The solution is :
Nf7 Re8 , Nd6+ exd6 , Rf3+ Kg6 , Rg3+ Kf6 , Rf3+ Ke7 , Re3+ Kd8 , Rxe8+ Kxe8 , a3 Bb7 , Kd1 Ra8 , Ke1 Kf7 , Kf1 Rh8 , Kg1 Kf6 , g3 Kf5 , f3 Rh3 , Kg2
And the fortress is built, now black has a bishop and a rook but he will never be able to penetrate your fortress just by moving Your king from g1 to g2 when black rook is on h column, and on move your king from f1 to f2 evrytime the rook is in f column ,
also black can change the moves orders but white can always keep on making this order of moves to build his fortress and force a beautiful draw... this is the magic of Chess...
