Black to play and win
A good work out today: worth spending time on: read this blog posting after you have looked at my other posting, posted a few moments ago, on the alternative black try 1…hg
J Baartman v D Morschel 1995
Solution
I spent a lot of time on this problem, including getting the pieces and board out. In fact, it turns out that 'most everything wins.
Reitstein prefers (in the sense 'only gives') the move played in the game, 1…Bf3.
Rather than descend into computer analysis, which this position is ripe for, I shall only give a few lines. If 2 gf not 2…Qf3? 3 Bc7+ with perpetual, but 2…h2+ 3 Bh2 Rh2 (Stockfish prefers 3…Qg7+ 4 Rg4 Qh7! assessing it as overwhelmingly winning for black) 4 Kh2 Qf3 and black is winning. If 5 Re8 black takes on f2, and checks his queen back to g6 or h5.
If 2 Rf4, then 2…hg!
I preferred 1..Rd2, and worked my way through the complications.
If 2 Re8+ Qe8 3 Re8+ Re8 4 Qc6 we reach the following position:
Then 4…h2+! 5 Kh1 Rd1+ 6 Kh2[] Rh8+ 7 Bh4[] Bd6+ 8 g3[] Rh4+ 9 Kg2 Rh8 and white has no perpetual, so 0-1.
If 2 Qf4, then 2…Qf4 was my intention (Stockfish says 2…Qh6 is even stronger) 3 Bf4 Bf2+ 4 Kf1 when my line was 4…Be1, which wins, but the engine finds 4…Be3!! which is even stronger.
However, when setting up the position in Stockfish, it prefers the simple 1…Bc8!: protects the queen, with a point being that if 2 Qc6 then 2…Bb6 and at the right time Bb7 with two enormous bishops.
I will end this posting here, simply because gremlins have entered. In one in a hundred postings, the app I use goes wrong, entering spurious font code, and despite my efforts, these can't be removed without wasting too much time. In addition, alignment of positions and text doesn't work. So rather than battle the impossible, I will end with this flavour of the answer.
