Interception or not?

[gandresch]

Hi,

questions on interceptions. A ist the thrower, B ist the catcher, C is the potential interceptor.
In a line each characters stands for one field, each line stands for a new row on the field.

Code: Select all

Situation 1:
A
CB


Situation 2:
A
C..........B

In each situation C is nearer to A and nearer to B than A to B. So the question is, can C intercept the ball?

What about:
Situation 3:
.............B
A
.C


Situation 4:
A
.C...........B

In all cases the interception rules seem to be filled (even though case 3 might seem dodgy, but can't argue with numbers), namely:

• C is closer to A than A is to B (i.e. not behind B)
• C is closer to B than A is to B (i.e. not behind A)
• I assume C has tackle zones
• range ruler passes over C's square (can't be 100% without checking, but case 3 looks like that too)

So, rules say that C can attempt an interception in all four cases.

As a side note, even if you moved C one square down in case 3, he'd still fulfill both proximity conditions, but not the range ruler part.

I've always taken 'closer than' to mean distance in squares, so I'd have said no interceptions there. Could very well be wrong though.

Yes
Yes
No (he isn't between the thrower and receiver)
Yes


there are 4 criteria to be met the third example fails this one:

be closer to the target player/square of the pass than the thrower is to the target player/square of the pass

We clarified this in the CRP. If you look at the interception section it now makes it more clear that it is not based on squares but actual distance.

But in the third case A is 13 squares to the right and one down and C is 12 squares to the right and 2 down from B.

A to B: sqrt(13^2+1^2) = 13.038
C to B: sqrt(12^2+2^2) = 12.166

So C is closer even though it seems wacky.

Good old Pythagoras. And people say they never use it after leaving school!

There's a 1/6 chance I cheated you!

Best keep an eye out when we play. I would hate to win buy cheating.

He's not between though.

Only a maths teacher would flog that old line.......

I agree he's not between, but that is not required by the rules as written now. In addition to having tackle zones three conditions have be met:

• Has to be closer to the thrower than the thrower is to the target. Check.
• Has to be closer to the target than the thrower. Check.
• Range ruler has to at least partly pass over the interceptors square. Check. (well, I don't have a ruler handy, but I think it checks out)

So nowhere does it say he has to be in between. Even though the rules are written to man that. This strange situation is just a byproduct of the range ruler's shape.

So even though I agree that in spirit of the rules it might not be right for C to intercept in case 3, but ruleswise there are no ambiguities that I can see.

Hi,

the problem for me was and still is, that the range ruler is broader than one square. So in all cases the ruler intersects the square of the interceptor.
To set Sit3 for no interception and all others seems a bit odd, because the situation is likely the same. So there are several possibilities to solve this.

1. The range ruler intersects the squares and the player C is able to intercept. (This is odd, because even I agree, that Sit3 is not clear in this case - it feels wrong).

2. We make the range ruler a bit tighter and then we have the problem, that even in the other situations, there might not be the possibility of an interception. Sit4 is a good example for this. The ruler has to intersect the square of C, so that C is able to intercept. If the ruler only is as tight as one square, then C will not be able to intercept at all.

So perhaps someone can clarify this situations and the handling of the range ruler for the general situation of an interception measure.

It is clarified in the new rules. However Jervis didn't listen to the BBRC so now I'm not sure the right answer anymore.

See Jervis screwed up and didn't put the new page 5 in the CRP despite being told that he really needed to do so.

Let's pretend for one second that Jervis listen to the BBRC and didn't screw up this piece of the puzzle. Take Page 5 from LRB 5.0.

If you read the new wording in CRP (and it is new since LRB 5.0) ... it says to measure the distance from the center of the square of A to B, A to C, and B to C with the range ruler (I just did it for case 3 its pretty obvious which is closer).

If the range ruler crosses the square of the C and (A to C)<(A to B) and (B to C)<(A to B) ... C can intercept.

It sounds like math ... put you don't need math at all. Just measure center to center with the range ruler and you'll be able to see in seconds which is shorter.

In this case I laid out Case 3 above on a board and did just that. In a couple seconds it was clear that under the present rules that C can intercept in all 4 cases.

Make sure you print out page 5 of the LRB 5.0 if you are printing out the CRP ... you need it.

The word "between" was too confusing so we ditched it. Now the Range Ruler defines between (ie if it touches the square it might be between). Then two quick measurements and you'll know the answer of if he is also closer to both player than they are to each other.
