Get out of the frame of mind that you're going to raise a certain amount with premium hands and stick with it. You have to find what amount it is that will isolate you with someone on THAT table.

Some tables require a 10x raise for isolation. Some you can raise 3x and feel comfortable all day long. If your raises are scaring out callers then your raises are too large for that tight table. Reduce it down until you get what you're looking for. You could even try raising 72 offsuit, bluffing someone out and showing. Don't think your just going to sit down at a no-limit table, wait on good hands, and then get action on them. You have to stimulate action.

You'll know you're in a good zone when your doubled up and everyone at the table is ranting about you in the chat module because you're bluffing them. I call it smacking the bees nest. Now you tighten up and get payed for your goods. When the action dries up, smack the bees nest again. Before you know it everyone will be scratching their head looking at your mega high stack. I wish you the best of luck in No Limit. Remember to mold your image continuously.
