What I enjoy the most are tournaments, especially regular ones where the prize pool is focused on the top finishing positions. I’m not a big fan of bounty formats, because they change the way the game is played and often encourage looser or more aggressive decisions just to chase bounties. That approach can be correct strategy-wise, but it’s not the style I enjoy the most.
I prefer standard tournaments with a normal payout structure. I’m fine with both slow and fast structures, it really depends on how much time I have and how much I’m willing to dedicate to poker that day. I also like spins, but only at very small buy-ins and when I’m looking for something quick and fun.
