You Not even stockfish 13 NNUE can find mate, so you are correct "Not sure if there is something better than a draw, but latest sting finds a draw very quickly with just 2 threads:"

Okay Hobacle, we give up, tell us if there is a win and how

Please spend some time reading the replies earlier and you'll find my solution.

White is really winning here by 1. Qxa1 unless I'm wrong.

Yes you are wrong, and NO computer is needed to see that after 1 Qxa1 Nb3+ wins the Queen and you simply traded your Queen for a Rook

I do NOT see the point for any engine to win with White or Black, since for a position to get your own Rook and Black Bishops blocked by your own pawns, whoever played with the Black pieces is a very weak player. and any engine rated at least 1400 will never block its own pieces on the first rank and on top of that the other Bishop Blocked on f8 the 8th rank is another sign of how weak the player paying Black was, if at least the pawn on the h file was located on h3 instead of h2, Black position would have been better because it gives its Bishop and Rook a chance to free themselves and play instead of just sitting there. Remember the advice by Raul Capablanca the most importance principle is to activate all your pieces specially during the opening stage and to keep them active ( Free and playing during the entire game.

NOTE: Black was playing without three important pieces that were BLOCKED by his own pawns. Simply play the same position with the h pawn on h3 instead of h2 and you will see how easy any engine will win with Black or any decent human player as long as they are equally rated or within 100 rating points from each other can win with the Black pieces with the h pawn on h3

If this was the position White would have never won, since at least the Bishop and Rook could free themselves and take some action , instead of being useless on the 1st rank==> [d]N2b1b1k/4p1p1/4PpPp/B1K5/3Q4/7p/3n1p2/r4Nbr w - - 0 1

This puzzle is a very nice intellectual challenge for humans or a demanding calculating-task for a computerprogram to solve. Don't understand your rant here.

It is very challenging for engines to solve, but only because the human who played with the Black pieces was a very weak player that blocked his own Rook on h1 and Bishop on g1 on the 1st rank with his own pawn on f2 and h2.. and to make my point even clearer I do NOT believe that Tarrasch Toy engine rated on 1450 would get his two pieces blocked on the first rank by its own pawn, so again if the position was this one with the h pawn on h3 instead of h2 blocking two of its own pieces on the 1st rank, Black can win easy against White. Now with the pawn on h3 the Queen can NOT take the Rook on a1 because it will lose with a fork Nb3+ and the Black Rook on h1 and the Black Bishop will be playing instead of waiting for the White King to take all of the Black pieces and eventually win
