My problem is as follows: I have the below schedule for a series of games between 4 teams. For these games, TeamX is allowed to scout any games of their next opponent prior to the match-up with TeamX's match-up with said opponent. So for example, AvsB is Game 1, CvsD is Game 2, AvsC is Game 3. A would be able to scout Game2 because Team C is their next opponent at the time of Game 2. How I determine who a next teams opponent is formulaically, then determine which games of that opponent they can scout?

I.e., In column for, I would like to formulaically "A" in the empty column for Game # 4 & 6, because Team D is Team A's next opponent at the time Team D plays those games. The fourth column is a helper column on the assumption it is easier to match to a martial match-up given there are are two columns a team could be found in.

Game #	Away	Home
1	A	B	A-B
2	C	D	C-D
3	A	C	A-C
4	B	D	B-D
5	B	C	B-C
6	C	D	C-D
7	A	B	A-B
8	A	D	A-D
9	B	C	B-C
10	A	D	A-D

What you're asking for is making sense but is more than a little confusing. Please add your expected results to the example so that we can be sure we are giving you exactly what is needed with a minimal amount of guesswork and incorrect answers.

What you're asking for is making sense but is more than a little confusing. Please add your expected results to the example so that we can be sure we are giving you exactly what is needed with a minimal amount of guesswork and incorrect answers.

See below for amended table. I agree it is confuses - I confuse myself as well. So, using 3 row (incl. header), the outputs are A & B because at the time C&D play, C is A's next opponent and D is B's next opponent.

Game #	Away	Home		Output(s)
1	A	B	A-B
2	C	D	C-D	A	B
3	A	C	A-C
4	B	D	B-D	A	C
5	B	C	B-C	A	D
6	C	D	C-D
7	A	B	A-B	D	C
8	A	D	A-D	D
9	B	C	B-C
10	A	D	A-D

There's something that I'm not quite following, could you have a look at the results in my test below and explain the differences?

For example, why should E5 be A and not C? Why should row 4 be blank? Formulas are in columns E and F, with your example results in H and I for comparing.

	A	B	C	D	E	F	G	H	I
1	Game #	Away	Home					Output(s)
2	1	A	B	A-B
3	2	C	D	C-D	A	B		A	B
4	3	A	C	A-C	B	B
5	4	B	D	B-D	C	C		A	C
6	5	B	C	B-C	A	D		A	D
7	6	C	D	C-D	B	A
8	7	A	B	A-B	D	C		D	C
9	8	A	D	A-D				D
10	9	B	C	B-C
11	10	A	D	A-D

Similar idea, with the same results

Just realised that E3,F3 is wrong as Bs next game is against D so cannot watch A-C, same goes for row 7.
However should E4 be both A & C

Another attempt, but getting messy.
