Shove way looser in most scenarios if you are questioning this really easy shove.
Just an example i would shove literally every single hand here, 82o i would happily jam, it really doesn't matter at this point since we're a long way away from the money. The range above ^ seems overly complicated. Just ask yourself in these situations and use common sense.
Questions to ask.
1. do i need the chips?
2. How desperate am i for chips?
Those determine how wide and risk averse you should be.
in this situation we're clearly very desperate for chips and we need to take risks to get close to being able to cash. But our actual goal in any MTT is to aim much higher than a min-cash, so we're going to need quite a few chips and we're going to have to double up quite a few times from this point to have any chance at all..
Thinking like this is basically what icm does, it's basically common sense.
Anyways, point is don't get bogged down with ranges that you will likely not remember. we're desperate, we need chips, we need chips to survive and to be able to cash so we're going to have to take risks. We're facing only one player, all of these things point to us having a very wide range. and it would be more risky to fold these spots overall. The worst thing you can do in tournament play is blind yourself out of the game. So when you have that 20bb stack, look to increase that to a 40bb stack, Work out how many chips you might need to be a bully around bubble time. you can do this by dividing the total chips in play by 90 players, and then do it for 9 players or whatever a final table is, that will give you a good idea of the average stack needed to get to those points, and it will help point you in the right direction of the amount of risks needed to do well. Obviously this is why icm is way more important in 9 man sng as you can win $$ even if you have 2-3bb which happens often especially in hyper turbo or turbo games. But you will almost certainly not do well if you are playign that stack size in mtt's, so icm is way less important, and getting that chipstack up nice and high is way more beneficial, but also you will be flipping more often and encounter more variance.
