Logical Progressive Chess. Find a game ending with:
a) 4. ?, DxSg3#
b) 4. ?, ?, Df6#
c) 4. ?, ?, Dg5-e5#

Solution

a) 1.Sb1-c3 2.e7-e6; Dd8-h4 3.Sc3-e4; Se4-g3; f2-f3 4.Dh4xh2; Dh2xg3#
b) 1.e2-e3 2.d7-d6; d6-d5 3.Ke1-e2; Ke2-d3; Kd3-d4 4.Lc8-f5; e7-e6; Dd8-f6#
c) 1.d2-d3 2.d7-d6 Lc8-g4 3.Ke1-d2; Kd2-e3; Ke3-e4 4.e7-e6; Dd8-g5;Dg5-e5#

Logical Progressive Chess

White start with one single move, then Black makes two single moves, then White makes three single moves, etc. The single moves can be played with different pieces. A checking move terminates the move series immediately. No castling, no Pawn double steps, no en passant.
