3D chess problems 
In the meantime I developed different sets of problems for threedimensional chess.
As examples I will list here three problems:
Problem 5 of Level 1
In a game there is the following situation:


Problem 3 of Level 2
White: QL1, KL1, Kd1KL1, Rb1W, Pawns: z1QL1, b2W, d2W, e1KL1 (6 pieces) Problem 4 of Level 2
Continuation of Problem 3 (of Level 2). 
To know if you found the correct solutions or not, contact Jens Meder; Weichselweg 9; 85241 Hebertshausen; GERMANY jens.meder@gmx.de.
Also there you can get the first set of threedimensional chess problems (level 1). Higher levels are to be send to those who did pass the lower levels.
