Not putting in several raises with a nut flush because you are worried about a straight flush would be a huge leak. I might not go to the felt, but It would take 7 or 8 raises (limit) before I would even think about calling. Straight flushes are so rare that you will cost yourself more by being afraid of them than you will by putting lots of money in the pot on the rare occasions when they are really there. Most of the time you will be shown a 2nd nut (or worse) flush.
