for this the simplest way is you lose in poker >
then on a separate loop you explore then search the kitchen and take a card and on that saturday noon challenge her to poker and you will have the option to cheat >
then on that same loop where you cheated in poker; on that sunday noon you talk to her on the beach/lake and pick "I wanted a challenge" (you will lose just like with cards) >
on the next loop you search the kitchen take a card and cheat to beat her again and on sunday you will wake up with the note in your pocket >
you then go to lin when she's in the bedroom sunday morning and pick "can I get your thoughts on something?" > "this note I found?" and then when you challenge her at noon again you can answer with what you wrote on a note with lin and you will beat lisa and unlock corruption 2
I haven't done more than that but it seems lisa's whole thing is more and more complex puzzles so good luck with getting further
