Preflop you're definately calling. Post flop since you have plenty of chips relative to the blinds against another big stack I would try and keep the pot small since I only have one pair. However you probably would have had to call more on 4th and 5th street, but you would have had more information. Raising certainly isn't a bad play but you do allow yourself to get semibluffed by two spades or K-J. The way it went I would fold and expect to have been behind the majority of the time. The only reason I said to keep the pot small against a big stack is because I heard Mike Matusow advocating this sort of play, and it has been working for me to avoid playing big pots when I am having no problem picking up blinds. Hope this was helpul.
