Solution of the two move:
Set game
1.… Kd4 – c5 2. Bd2 – e3 mate
1.… Kd4 – e4 2. Rf5 – f4 mate
1. Nc4 – e3 (threatens Qc4 mate)
1.… Kd4 – c5 2. De6 – d6 matt
e4 Kd4-1 ... 2 Tb6-b4 matt
Solution to the study:
1. Ka6 + would be wrong? Kc8! 2. Rc3 + Kd7 3. Rxd3 + Qxd3 + and the fork Nc5 + is out of the question because White is in check .
1. Ne6 – c5! Qe3xc5 +
2. Kb5 – a6 +! Kb8 – c8 2.… Ka8 3. Rb8 + Kxb8 stalemate 2.… Nb4 + 3. Rxb4 + Qxb4 stalemate and after Kc8 4th Rb8 +! is a rook versus queen draw game on the board.
3. Rb3 – b8 +! Kc8 – d7
4. Rb8 – b7 +! Kd7 – d6
5th Rb7 – b6 + Kd6 – d5
6th Rb6 – b5! Nd3 – b4 +
7. Ka6 – a5! and there is nothing more than permanent chess for Black because the queen remains tied .
Stereo chess
In 1975 Jensch invented the three-dimensional chess variant "stereo chess". A 4x4x4 cube is placed on the central square c3 – c6 – f6 – f3 on the normal 8x8 chess board, which serves as an additional playing area.
Private
After the Second World War, Jensch worked at the Frankfurt Opera as an assistant director, later he took up a commercial profession. Since 1979 he lived in Vasia (Italy).
