Passive opponents

[ne14poker]

How do you adjust your play for passive opponents?

I've been playing 1/2 at Empire. I deposited 250BB to collect the reload bonus. I won 60BB at Party last week and started up 35BB at Empire and then over the last 4 sessions I've lost 45BB.

My VP$IP is 18%. I think that I play pretty good hands so I don't think that is my problem.

The tables that I was playing at were unusually passive. Both tight and loose passives, but definately passive. I rate passive as Aggression Factor <1.5 (excluding preFlop).

I'm only down $20 with 100 hands to go for my bonus. It is not the end of the world, but I'm puzzled. They seem to play Axo, any suited cards and reluctant to fold their blinds. It just seems that the only time I can get them off a hand is at the river when they couldn't catch their draw.

Is this passive trend a bonus chasing stragegy? Will it disappear once the bonus expires?

How do I adjust my play?

Should I discount more outs since they could be playing anything?

Should I stop raising top pair unless the board is completely uncoordinated?
