I have never been a fan of the "post poker craze" "Rebuys" (not a rebuy) offered by casinos, it is a money grab of the worst kind.
Major venues haven't used actual "Rebuy" tournaments in over a decade, they use "Re-Entry" under the guise of "Rebuy"......which are 2 completely different things.
Pre-2007, when you played a $1000 WSOP "Rebuy" event, your initial entry was paid with the usual ~10-12% to the casino/WSOP and then if you busted out, you literally stood up, shouted rebuy, threw a floor person another $1000 and sat back down in your SAME SEAT and that $1000 went ENTIRELY to the prize pool......
What the casino's realized they could do was nix the "Rebuy" part, but call them "Re-Entry" instead and then you have to go back to the cashier cage, pay your $1000 buy-in as if you were new and they rake the 10-12% from the $1000 and you get randomly seated somewhere away from your original seat (usually).........
The best one I remember was when Daniel "went off" for 48 rebuys in a
$1k WSOP in 2006
TLDR: Rebuys - Good, Re-Entries - suck balls
Unfortunately, the poker playing public didn't give 2-shits about how they ran the tournaments, so Rebuys quietly went the way of the dodo bird and Re-Entries are here to stay......I agree with Daniel, especially for the high-rollers.....
