The fact is, there is litle statistical difference between a 3-6 bid over a long game. One battle here or there provides the same infantry gain/loss. All a small bid does is make a first round attack easier/harder (or potentially dissuades that attack, in which case the attacker goes elsewhere).
As a basic example, we will purchase an inf/tank, one placed in UKR (to somewhat dissuade an attack there, or to aid in taking more tanks) and one in Lybia.
A Normal attack on Egypt can involve the transport, or not (should Germany decide to go west instead). W/o a bid, Germany can bring 1 inf 1 armor, 2 fighters (reason for UKR bid) and 1 bomber (14). Egypt has 9 Defense.
Germany should get 2-3 hits the first round. UK should only get 1-2. This is sufficient force to “guarantee” taking the fighter, but not the territory.
Adding a bid unit means you are more likely to take Egypt, but in “many” games Uk will only get 1 hit back. I’m sure everyone has also seen UK get three hits as well. So the bid unit could just as well be lost.
Now, as to the unit itself, an art or armor makes the attack force a 17. Still not quite a “guarantee” of 3 hits, but close. But the UK still can hit back, possibly with 3, and 50% at 2.
The point is this…
In 50% of the “w/o bid” games, UK may only get that 1 hit. In which case, Germany has 1 unit (armor) left.
In 50% of the “bid armor” games, UK gets 2 hits. Germany still has 1 armor left.
That bid unit actually left you in no better shape than you would have been in without any bid, but UK got one less hit in defense.
And certainly, there is no difference (from this point on) in the game to say that having the bid “won” it for you.
Bid units generally only make first round attacks a bit better or worse odds wise. The rest of the “effect” is largely inside people’s heads.
The secondary effect (dissuading a first round attack in UKR) may happen, but the result is USSR just attacks elsewhere (belo/WR) OR perhaps USSR wasnt going to attack UKR in the first place.
You are entitled to your opinion. Likewise I am to mine.
