Daily chess puzzle: Check Mate #54

Another puzzle from Dragoslav Andric’s 1981 book “Matni Udar”.

White to play and win

Teichmann v unknown, 1903

(not worth spending much time on: cooked- perhaps try to find the purported line, and the bust)

Solution

I struggled in vain with this one. My try 1 Qf5 works against everything but Bb7 or Ba6, bringing the Ra8 into the defence. And I couldn’t make 1 Rh6 work, but that is the solution: 1…Nh6[] 2 Qg5 Nf7[] 3 Qd8+ !! (alleged) Nd8[] 4 h6 but simply 4…Ng6 is 0-1, or 4…Ng2 is cuter: 5 Rg2 Qd1+ and 5…Qh5 to defend h7.

White is just lost in the opening position.

A bigger puzzle: how did the game position arise? White is two pieces down; what was Black’s last move?  I have no answers.
