Thanks for the further explanation. I guess I have trouble with this concept of specialists providing "fair auction market price" since they are the ones who get to set the price. So if a large seller comes in at market when there's no buyers, and the specialist is forced to become the "buyer of last resort" I've always seen them lower the bid dramatically so that they can buy in very low, then "work" the price back up (say, by showing large size on the bid + small size on the ask) just so they can quickly sell what they were "forced" to buy ... at a very handsome profit. So unless I'm missing something it's hard for me to think of them as "good guys" or "fair".
I think what you're missing is that trading on the NYSE is about more than just you and the specialist. It's not like the specialist participates in every print, the majority of prints are crosses between customer orders. And when you're talking about fairness in terms of price it has to be fair to both parties involved. When a large market order hits a dried up market and you havea bid or offer in on the opposite side your fill will be price improved accordingly.
Unless you're dealing with a rising market it's also often a better idea to bite the bullet and unload everything in one block since the price you get will usually be better than the average price you'd end up with if you tried to parcel it out. In addition the market impact of large orders in NYSE stocks tends to be much smaller than on Nasdaq stocks with similar liquidity because unlike MMs the specialist is bound by rules to provide an orderly market and can't simply switch into "I buy only 100 shares every half point" mode.
You can't be mad at the specialist for trying to buy low and sell high as long as he doesn't stretch his discretion beyond what constitutes an orderly market. After all just like you he's in this business to make money. But you can easily join him and profit from his moves. With many specialists you can tell beforehand when a large block is about to hit that will gap the price up or down. And with stocks that have the tendency to bounce consistently after such prints you can take advantage of it. RIG and BJS are examples where this works well as long as you only do it in alignment with the stock's and the OSX short-term trend.
