pardon the silly question, but friend and I were of differing opinions on the combat odds ratios, and we're looking for clarification.
- if 11 attacks 4, that is 2:1 odds
- if 4 attacks 11, is that 1:2 odds or 1:3 odds? my friend believes you always round in the defenders favor to be consistent.. so, 4 attacking 11 would be 1:3 odds. is this correct?

Yes that's correct.

This is correct, you always round in favor of the defenders. If you look at the examples of play you'll see that rule in action.

There is not many units in the game, and the different stength values (plus low stacking) were designed to limit complicated computations of odds as much as possible (yes, I really looked into this, too!).

If you still find you are searching all around the board for that extra combat factor to make the perfect odds for that critical attack, or playing a game of Counter "Musical Chairs" to do the same, then I have the perfect solution for you: use Optional Rule (15.3) Local Combat Support. It was designed for that need.

I been reading the rules on line (before my copy arrives) and I am confused by the "odds ratios" rule. In the example in the rule book, it says 12 vs 9 = 1.33 which comes out to a 1:1 ratio. But 14 vs. 9 is 3:2? I don't know how to get there. Per the rules, if I divide 14 by 9, I get 1.555. How does 3:2 come out of this?

The game looks fabulous. But this has me stumped.

Couple ways: As you say 14 divided by 9 is 1.555. 3 divided by 2 is 1.5, so 14:9 (1.555) would round down to 3:2 (1.5).

Another way is a little more complicated: 9 divided by 2 is 4.5. How many 4.5's go into 14? The answer is 3 plus a little bit more, so it rounds to 3:2.

Anybody got any other tricks for quickly calculating odds ratios?

Thanks, Mike. I really appreciate it. That is helpful. But it still seems a bit inelegant for such an otherwise elegant game. I think that some math wiz out there should make a simple table for all of us. It would be a cross-reference chart, like the CR tables of these games. Down the side would be the defender's strength and across the top would be the attacker's strength: find the intersection and, voila, you have your "Odds Ratio" right there. No need to do the math for each battle.

So, Mike, I have been enjoying the Geek for years, but this is my first post. How do we ensure these postings are being read by all the NR-fan math geniuses out there? Do we start a new thread? And then would it be at the top of threads? It's a pathetic question, I know!

Thanks.
