Hey all,
I just did LG Game #2 from PT 09, and in the game there are 2 biconditional rules and 2 conditional rules.
J (-) /K
N (-) /P
N -> L
Q -> K
JY does not combine the biconditional rules with the conditional rules, and instead just splits the GB based on the biconditionals.
Should we never combine biconditional rules with other rules?
Would appreciate any feedback/advice. Thanks so much! :)

thanks for the advice/feedback! :) @leahbeuk911 @akikookmt881
The game board splitting is really just a unique thing to each game. I'm not looking at that one specifically right now, so don't see what JY did. But as a rule, yes it is possible to link up biconditionals.

Yes, you definitely can chain up biconditionals. Like, those would be:
J (--)/K --> /Q
The other one would be trickier though. It's more like you split off of N in directions. Because if you do the contrapositive of /L --> /N then it doesn't link up to N (--) /P. You would have to make 2 lines going away from N to represent both N --> L and N (--) /P. This is a lot easier to do if I could write it out instead of type it hahaha.
(ETA: tried to visually represent this, didn't work out. Deleted the mess haha.)
In some cases, I think you should combine. If there is a question asking “not both” pairs, drawing J (—) /K —> /Q would make it easy for you to pick an answer choice J and Q.
