Solution to Puzzle 6: (WARNING, SPOILERS)

Germany: F BAL S BER, A RUH & A BUR S MUN, A GAS-NWY, F HEL-DEN, F SWE S GAS-NWY.

England: F NWY-STP, F NTH, F ENG & F MAO C GAS-NWY, BRE-GAS.

The only interesting case is when STP-NWY is bounced by MOS, then NWY should retreat to BAR.

The hardest case is when this is a fall turn and Russia builds in STP (we assume Russia is hostile). If it was a spring turn, one can always wait a turn (ensuring T doesn't take STP of course) to reduce to this case.

Winter:
Germany builds in KIE
England removes F NTH

Stalemate part:
ENG S MAO, POR S SPA, GAS S MAR, BUR & RUH S MUN, KIE S BER.

Capture STP part:
Spring: A NWY-FIN, F SWE-NWY, F BAL-GOB, F DEN-BAL.

Fall: At least three of the four spaces adjacent to STP will be occupied by EG forces. Use a double supported attack on STP and BAL-LVN to guarantee that EG take STP.

From a puzzle composition point of view, I like how this solution relies on the German fleet being in HEL and doesn't work if it is in HOL (but I haven't checked that no solution exists in that case).

The first set is exactly as intended - well done!

Follow up is correct as well. And it seems to me that there is a solution even if HEL is moved to Hol (assuming bounce in StP):
After builds:
Nwy > StP supported from BAR ,
SKA>Swe, Hol>NTH, BAL > GoB

If R stays in StP there is no problem,
If R moves/retreats to Finland (after possibly bounce in GoB):
Sweden will attack Fin in the fall, cutting any possible support. The conclusion is that R/T can at most support the Russian unit back into StP, but they can't get a Turkish unit into StP.

Nice.

Now you've solved it with HEL moved to HOL, I prefer the puzzle to have the fleet in HOL instead of HEL.

Thank you for these puzzles! 6 was really tricky and fun. 7 was easier, but the solution was something I'd never seen before.

I'm happy someone enjoyed them!

I got linked to these a few days ago. Really enjoyed doing them, thanks RoganJosh!

I made a puzzle of my own:

You're play testing a new map. You're playing as Blue, it's spring, and you're 1 SC away from winning. Elsewhere on the map you can guarantee to gain a centre, but Red is attacking your two coastal centres pictured here. How can you defend them both?

Given there's no spoiler tag here, I've sent my solution to you via PM TGM!
