Hey y'all just in a bit of a rut and need some clarification from my 7Sage peeps. When the term "unless" is used in a logic game rule with other groups things get kinda dicey for me quick.
For instance in an In/Out game if there is a rule which combines the negation of a player via the group 4 "not" or "cannot" group in the conditional I can't for the life of me get it down who gets negated and ends up in the sufficient. Example:
"cannot select J unless W is also selected" . Question: Do I negate J to /J via cannot, then negate my negation of /J again via "unless" to end up with: If J --> W ? Is this correct?
I thought I had this mastered until I took PT 87 Game # 3 (Double layer Sequencing)
"Hanbock cannot be shown earlier than the third week unless Ibex is shown in the first week"
Who gets negated, how, and ends up in the sufficient? Sorry if this is painful for those who have mastered LG conditional logic. Thank you for your help!

Cannot...Unless is super common on LG and honestly, I translate these only when it's group 3 or group 4 independently.
Group 3+4 are the easiest to handle because they cancel each other out, so you just drop them:
Cannot - negative
unless = if not - negative
2 negatives make a positive
So:
x cannot be in group 1 unless y is in group 1
x cannot be in group 1 unless y is in group 1
x in group 1, y in group 1
This is equivalent to all these:
IF x in group 1, THEN y in group 1
x in group 1, ONLY IF y in group 1
Hope it helps.
And in regard to the inferences - I have been in the same boat - drilling games with conditionals is key, but find games that JY splits the board and force yourself to do them just by using the conditional chain. PT43 G3 is not too difficult, but good practice.
I really like PT41 G3 - it has 2 bi-conditional and it was a real cluster for me in the beginning. JY solves it with 4 boards leveraging the bi-conditionals - do it just following the chain.
That's an excellent way to retrain yourself via omission of "cannot" and "unless". I like that a lot. I will def check that game out. I haven't taken anything in the 40's so this is perfect for me. Thanks for your help
