Adjust to your normal strategy when you are down to one re-buy.
You are never down to just one re-buy unless it is self-imposed - and even if you are just going to allow yourself one more no need to adjust your strategy.
Go all-in with any pair if only limpers or all folders came in before the flop. Call any raise up to 8x the big blind, otherwise fold.
This is wayyyyyy too general. You can never pre-determine your action like this - there are other factors such as stack size that have to be considered - even if it is a re-buy. 8x the bb could be dumb if you are only leaving a few chips behind.
Go all-in with any 2 cards that are paint before the flop unless there is a 6x raise in front of you, otherwise fold.
This is really bad advice.
Raise 4x with any Ace if no raises in front of you, otherwise fold.
You can not pre-determine how you are going to raise every time without looking at other factors like stack sizes, position and how others are playing at the table.
Call with any Ax suited as long as the raise is less that 50% of your chips.
Horrible advice - sorry. You are going to call a raise for 40% of your stack with A2s in middles position????
After the end of the re-buy period there will be an add-on period. Take advantage of this unless you have so many chips that you don’t need the add-on. As a general rule, if the add-on will give you less that 10% of your chips or if no-one can pass you as the chip leader then do not add-on. If you can become the chip leader or if adding on will increase your chip stack more than 10%, then go ahead and add-on.
As a hardcore rule - ALWAYS add-on regardless of your stack
I think it's a loose game strategy
. but it allows you to count on the high places of the tournament
