Guys I see nailing 6 figure scores with 2-3 rebuys on the regular who are Pro Rebuy:
CDarwin2, Probirs, Greenstone25, p0cket00, Lena900, Belabasci, LrsLzk, 1_connor_b_1, BlancoNegro, ImaLuckSac, European, shaundeeb, ImaLucSac, MrTimCaum, lasagnaaammm, MrBittar, Bounatiro, nl_profit, McZhang, Krissyb24,JoaoMathias, TheNerdGuy, ZeeJustin, bencb789, SkaiWalkurrr, Big Huni.
Only pretty much all the top online tourney crushers in the world. I think I'll side with these guys on the rebuy, pretty sure they know what their doing lol. I watch them a lot and they don't always rebuy but they do it pretty often so make of that what you will. Part of that is because of their bankrolls, their hourly, and the fact that the prize pools are very large usually in comparison with their buyins so the size of the prize pool probably factors into the frequency in which they decide to rebuy. I probably see CDarwin2 and LrsLzk rebuying 1-3 times the most frequently and they are absolutely crushing it this year and on major heaters. So make of that what you will.
ZeeJustin just had a 315k score where he did 2 rebuys. European just had a 196k cash where he rebought twice and he rebuys often. Probirs rebought 3 times in a tourney where he just cashed for 54k. GodOfHU turned 2 rebuys of 2k into a 121k cash. LrsLzk/Sami Kelopuro just had a 100k and 60k cash where he rebought twice both times. Like 70% of the time LrsLzk nails a big cash he rebuys 2-3 times that guy is the rebuy king and he's probably the hottest player in the world of online poker right now. These guys are the best online tourney players in the world so I'll side with them on rebuying. Though most people aren't them. If you are a profitable player with a solid winrate, have a healthy sized bankroll for it, and if you grind out a decent size volume then rebuying makes a ton of sense and you should absolutely do it, but if you aren't profitable and if you don't have a healthy bankroll for the stakes you play and if you don't grind out a decent amount of volume then hell no you should never rebuy. Check out all the biggest completed tourneys and watch the biggest tourneys on Stars, you will always see the top players nailing huge cashes with 1-3 rebuys. The majority of top players are big proponents of it.
