Thing is, if they're all playing a passive minraising game amongst themselves, while seeing a lot of flops, then this has the potential of being a great table. They'll probably shit their pants and fold the first two times you raise big, but then they'll start calling.. and some of them might even be inspired to start betting bigger too (cuz it's crazy and fun!). This is how it is/seems to me, you have a different experience at those tables?
