How do you approach rebuys? I tend to pay my buy-in, then try to outplay others to build my chipstack before getting some more chips during the add-on.
Other people believe you must rebuy early and often in order to give yourself a big enough stack to bully others off the table. They budget for a minimum of 3-4 times the buy-in plus an add-on later.
Which approach do you favour? Or maybe you've got another secret to rebuy success?
