Well I like Re-buys.  First thing you have to do is set aside the cash you want to use before hand!  For an example if you are going to use the 10% bank roll rule in a tournament and the tournament is $5.50 buy in and you have $20 in bank roll it is a no do,  buy $200 set aside 3 buy ins after the first one to use in case you need it.

It is an other way to see the other person hand to if you are early in a tournament!

As to add on I look at where I am in standings before you lose the add on and re-buy options.

I have not to re-buy or add on quit often, but you have to beware of those who use re-buys as weapons!

More strategy involved for why and when to do it.  <=== the weapon part

I do not like rebuys.

I am not a great poker player (sad but true). When I have been in rebuy tournies I find that people bet like they are crazy because they know that they can rebuy. They often bet just because they are holding an ace. More than once, I have laid down the winning hand because of that.

On the other hand, I have won rebuy tourneys without ever rebuying once, I just added on in the first break.

Congrats on your win.Those are some  nice hands.

But not all re buys add the re buy to the pot.
What if you were playing in a garanted tournament.
when you re buy in those tournaments the pot does not go up.

I agree with Drunker1 1000 or more percent on his view and ask the question as to where does the money go to if not to the pot?

Only way I might go in one of the tournaments where the pot does not grow, is if it goes to a charity I like!  And I mean 100% including rake!

At 10% rake the poker sites and casinos are get a ton or more money than I like them to get!

Nice win there by the way Drunker1.

That situation I stay away!  I like full tables and bigger tournaments!  You are in a wacky sit and go with little control there underdog!  Since I like to have a 3 to 4 re-buy reserve none of my reserve does not go to prize pool an d therefore not a good investment of bankroll or time!
