Hey all I started playing mtts and noticed that early position is a problem for me. Not sure how to approach the situation with about 10bb.
When i consider shoving should i choose hands that are ahead of calling ranges? aware looking at whos in blinds is important since they get better price bla bla but not sure how to estimate profitability of shoving some hands early.

should i just be using icmizer for this spot to work out a range?
