It is interesting to read these forums. Plenty of people on here have good thoughts on nominations, reasons, votes, plans and strategies. As we watch each episode of the show, it is easy to see the good and bad plays, and work out what should have or should not have been done. That is because we can see the bigger picture, we are shown both sides and what they are doing/planning (or both alliances if you want to put it that way). Therefore it is easy for us as outsiders (viewers) looking at it from the comfort of our homes, and with forums full of people to discuss it with.
However, in the house, it is a whole different game. You are essentially alone, albeit maybe with one or two close friends/allies. No forums there to ask lots of people for their opinions. And the pressure cooker it is. Players who have been in the house often talk about having a plan before going in, and thinking they will be good at strategy, but once inside they say the pressure is intense and your thinking can go to crap.
I have often wondered what it must be like. I reckon I have a pretty good handle on playing it and how it should be done. But, if the pressure in there is what they say it is then I'd reckon all my plans and thoughts would go straight out the window pretty quickly and I would look like a typical idiot in there with no clue.
