Chip equity or ICM?

I wouldn't use ICM or cev, I'm not sure either are useful in this instance. ICM is dependent on the payout structure of the tournament, and you probably need more equity than cev as you have to take your tournament survivability into account.

If he has raised your blind 3 times in 37 hands then I am happy to shove this as he might call with worse if he thinks you are playing back at him, and I'm guessing he is folding a lot of his range and you can pick up the pot without playing the flop. And restealing here shows that you will fight vs his steals.

There seems to be some confusion about the ICM concept here. I would recommend the following article in the SNG section (to both of you): Independent Chip Modell
Unfortunately it's for silver+, so Wohmfg will have to grind some more (or buy some points in our points store) in order to get access.

ICM isn't something you can switch on or off depending on the situation. It is always there and always of importance. OF COURSE you have to take ICM factors into account in every single situation that you play. The deeper you are the more important it gets.

In your specific situation it is not THAT important fortunately. The most critical spots are those where you have to call an allin for your whole stack. In your hand you will have the opportunity to push against your opponent. He will have to make the decision. Therefore ICM isn't a big problem here (at least not for you).
You will have a lot of fold equity in this spot and should shove a very wide range. I would recommend:
22+, Ax+, K2s+, K7o+, Q6s+, Q9o+, J8s+, JTo, T8s+, T9o, 98s, 87s, 76s

As you can see AQs is an easy shove in this spot. You don't just have a lot of fold equity, you are in front against his calling range as well (and there is no need to be in front against his calling range because you have a lot of fold equity).

Ok, thanks both.
I think I often get too involved with larger stacks, which is why I was worrying about it.
