Here is one set of bid rules.Â It is among the most complete sets.
Caspian Sub Bid Rules
1. Roll for high roll to see who gets the first bid.
2. Conduct the bid like â€œName that Tuneâ€.Â The player with the first bid says â€œI can win with the Axis and X IPCs.â€, where X is the number of IPCs the bidder receives to play the Axis.Â You are always bidding to play as the Axis.
3. The other player either lets the first player have the bid or counters with a bid that is smaller than the first bid such as, â€œI can win with the Axis and X-2 IPCs.â€Â This is a bid-down system.
4. Keep going until a bid is accepted. If the bid â€˜goes negativeâ€, then the bid becomes â€œI will take the Axis and give the Allies X IPCs.â€ Counter-bids then become higher values given to the Allies.
5. Once the bid is accepted there is a pre-game bid placement turn. Whoever is getting the IPCs may buy units to place on the board.
a) Unit costs are normal
b) Land units can be placed in any territory a power controls
c) Naval units can be placed with other naval units or in territories adjacent to a powerâ€s land
d) There is a limit of 1 bid piece per territory
e) Powers cannot put their units in another powerâ€s territory (i.e. no German pieces start in Japanese territory)
f) IPCs do not have to be spent on units.Â IPCs not spent on units can be given to any of the teamâ€s powers.
6. Play starts as normal with the Soviets.
Discussion of why the rules are crafted this way are in the CSub rules paper, Policy Paper #03.
