How To Play Against Loose Passives?

[guitarizt]

I am the person that is not able to deal with this player, and yes it does lead to big downswings. I'm weak tight so I usually wait for a hand before trying to get 3 streets of value, or checking the turn and valuebetting the river. The only problem is if I run pretty cold I go through these not so fun downswings. I've traditionally had my worst downswings on fridays when more fish play. I adjusted by tightening up and playing like 15/12 and not cbetting as much, but this still isn't optimal as I had another bad day this past friday. The 4+ buyin days really suck, but if I'm doing good on friday I only make like 2-4 buyins where if I do bad I lose twice as much.

This post helped me realize my problem.
