[Retros] Five retro problems from Stuttgarter Zeitung/Corrections

[keilhack at aol.com]

Two corrections regarding Problem Nr. 4One in the task, one in the solution - my apologies again! 
Werner Tüngler, Schachfeld 2014, version

It’s White to move in a position with 5 chessmen, non of which is on the h-file (this condition was forgotten in the translation! Without it, also Nh3 is possible). White is winning. After a rotation of 90 degrees clockwise it’s a draw. After a 180 degrees rotation White loses. After a 270 degrees rotation it’s an illegal position.
Which is the position?Solution: a) the original position is wKc7, Bb8, Nf3, bKa8, Pg7 (not Bg7, as pointed out by Noam D. Elkies). Possible last moves are sKa7-a8 b7-b8B+. White is winning.
b) rotation 90 degrees to the right (wKg6 etc.): 1.Ne2 g1Q+ 2.Nxg1 drawc) rotation 180 degrees (wKf2) 1.N to any square b1Q, and White losesd) rotation 270 degrees to the right (wKb3). It's White to move, but there is no last move from Black. The position is illegal.
An unique solution!
