You absolutely can not minraise 100% as button, that's crazy. You can't use HRC or ICMizer to determine profitable opening ranges, because these programs assume that you cannot get flatted and that it's a 3bet or fold game. People flatting you, even out of position is bad for a wide opening range. High stakes regs found out years ago that someone flatting even decently wide in the big blind plus 3 betting a decent range will shrink your profitable opening ranges by a lot. With ICM at 20 bbs against even marginal players an open of more than 45% is probably going to be negative ev. With 2 world class players in the SB and BB, you could not open more than about 35-37% before your opens would start losing money, because very solid regs play 80% of BB hands vs a BN open.
The trick to being able to play a wider range from the BN is to limp a certain part of your range because people are unsure of how to play against a limp strategy from the BN at that stack size and make some pretty big errors, which allows us to squeeze in a few more hands that can be profitable. In this exact spot vs regs in the SB and BB, my range would look like this:
color key for said chart:
Order is "your action/your action to a 3bet NAI/Your action to a 3bet Jam.
There would actually be a few more limp traps since the BB is short in this scenario, this range was made assuming the SB and BB are relatively equal stacked to you.
Against very bad regs or randoms I would do very little limping and just open a wider
range, but even so that range is not going going to be more than 40-45% and probably even less in this scenario where I expect the BB to get in wide because he's short. If you consistently open 50% or more as BN here, you're leaking money like a sieve.
Edit: And the 3bet call ranges will be off, given how short the other stacks are, this was a general range created awhile ago under less heavy ICM circumstances.
I went ahead and ran the hand for kicks and with appropriate 3betting ranges we can get in a9o solidly and a7s solidly vs BB, along with KQs. Obviously against the SB our call off range is super tight, somewhere around 1010+ AQs+ AKo. Calling the SB with anything wider than that and you're playing with fire.
