I prefer re entry to rebuy tourneys. If you take a bad beat you can just start over with starting chips. Not like in rebuy where u just go all in every hand, bust out, double rebuy then add on. It's just a much more fair structure in my opinion.
I actually like R+A events. You just need to understand, what the correct strategic adjustments are, and they are basically the opposite of, what you suggest. When the add-ons are purchased, the value of each chip goes down, so the end of the rebuy period is almost like a bubble. You want to make it past the rebuy period, and ideally without having to fire several bullets.
People, who dubble rebuy and splash their chips around trying to build a big stack, basically just sweeten the price pool for other players. And this is great, because when other players make strategic mistakes, we profit. On the other side we also profit from those players, who dont purchase the add-on, even they have the option.
And finally there are still some R+A tournaments, where rebuys and add-ons are not raked. More rake is really not better, so if you play on a site, that has those tournaments, you want to play those before higher raked events.
You just need to understand, that R+A events require a larger
bankroll. Because of the large number of rebuys and add-ons, a 2,2$ R+A on
888 Poker is really more like a 5,5$ normal tournament and should be seen as an alternative to those.
