Thanks for the thoughts.

Nash, you say the PP players at this level play looser than I expect. I guess the reason I was hesitant here was more the fact that someone very loose could have called me with A x, as they did, but have hit their 'x' card on that ragged a board. Or would you think that, if I was beaten in that spot by a two pair hand he would have played back at me by now, by re-raising? I guess I assume that, with all the passivity amongst the little fishes (sorry, Adam, customers) they could have pretty much any hand from bottom pair to top set in this spot.

I suppose the main point here is when you don't know 'for certain' you are winning, better to save those last 200, and still have a small chance at cashing. Your point about maximising survival is spot on.
