Hi all, I would say play tighter and make them pay more to see each street (more than normal ) , however it really depends on the "dumb" player's aggression factor/style, are they dumb calling stations or raising stations?
Calling stations are much easier as you can get real strong hands/nuts and bet heavily into them without fear of chasing them away , a "raising station" is much harder as you will be faced with more risks, to those I'd play tighter and pick your spots, Against some players i use the "let people do your work for you" idea , for example if raising station is on my right and there are good strong players on my left who don't get bullied easily, i will simply sit back and wait for other players to deal with "raising station" or else go as far as instigating "trouble" and when other players raise etc, i fold and let them fight .... lol
