This nugget completes my strategy observations of Imperium.
I hope this will encourage you to enter more tournaments, where you will usually find me!
Thanks to M3 for the encouragement.

The 'black point' congestion problem was explained earlier.

The following position demonstrates the problems of not having solved that congestion by the middle game.

In each variation the RC is blocked by friendly pieces on the black point complex.
The congestion also weakens the white point complex which the GLW exploits in all the variations.

(In set up, the notation LY C8/4 means The Red Lance is on C8 and has been rotated clockwise 4 turns).

RED: C E9/0 ; LY G9/0 C9/4 ; PV F8/0 E7/0 ; PI C4/1 ; S D6/0 .
GREEN C D2/0 ; LY G1/0 ; LT H1/0 B4/0 ; LW F5/0 ; S D4.


1: B4->B6 wins:

1 ... E9/1 2: B6/1# and no matter where the RC goes, the GLW has a checkmate next move.

1 ... C9-C7 2: C6->C9# and the GLW has a checkmate next move.

Best try is 1 ... C9/4 then

2: F5->F7 E9/1 (2 ... C9->D8 3: F7->E8##)
3: B6/1# C9->D8 (3 ... E9->F9 4: F7->G8##)
4: B6-x D8# E9-F9 5: F7->G8##
