When do you push when you have a small stack?

Generally when you play tournaments and say it gets down to 7 handed at your table whether its the final table or just a table that has 7 players left and you have 16K and blinds are 1k/2K and ante i think is 200 maybe? What hands is good to go all in when you have say 5 guys left, 3 players anthe blinds.

Today i pushed AJs all in and nobody called me. But later i made a terrible play i think, it was 2 hands later i had A10s and folded Utg when there i was first to act with 6 players left at the table. Is that terrible?

I know that if i was at the CO, A10s or A10o is an obvious all in with my stack. But what about when theres 4,5 or 6 ppl left to act assuming my stack size of 16K with 1k/2k blinds with 200 ante. Is any pair a good push? Would it be better pushing a hand like 98s than A8 because when someone calls you and have an Ace, they have u dominated most likely

Later i pushed all in with 88 in utg+1 and there were about 7 players total and I had an M of about 3. I had 5 more people left to act and pushed with 88 and lost. Is there a guideline on what should be the minimum requirements assuming all players play solid?

Thanks.

I like the money in the pot =~20% of my stack in any position other than the BU or SB. I'm looser there, but not with multiple limpers.

Can you explain what you mean here? I have no clue what you just said. Thanks.

Typically your position to push is offplayed by the fold equity you get by being the first into the pot.

However, if you're talking about 45 turbos, etc here go for later position pushes and let the table kill itself here.
