I guess you mean 7-15 big blinds when you say, (you have like newhere from 7-15 along with the opponent, but when heads-up you should play more hands than when you do when there are several people left. Because the blinds are so high you are probably more inclined to going all-in faster than normal, but in my opnion this depends on your chip stack too. If you are HU and have the other player dominated in chips, you can fold a lil' more. You should when you have the short stack in that situation, don't do it with the likes of 6-2 etc. But you should be aggressive, although i think it's a bit diffucult when in a SNG at times, again because of the blinds...But still chances enough for 1st place...
