half of the advice above is backwards. Thanks.
Big stacks don't necessarily call looser. While they want to increase their stack, they don't want to punt it off either. Wht will affect their calling range is their knowledge of proper calling ranges and their read on what you r shoving range is. I didn't say they would call looser, I said if they were loose they would call more with less. The larger the stack the wider the range is obvious... if you're big stacked with AT you're more likely to call a shove than if you were a medium or short stack, especially if the person looks like they're stealing. hence the phrase 'don't mess with the big stack.'
-Big stack calling off with Ax after 2 ar alrady in the pot is borderline stupid unless it is AQ+, AJss+ at minimum. Anything smaller Ax would be throwing away money unless they have 100bb and you both have 10bb and they just want to make a dumb gamble, since 1 or more of the allins likely has an ace already. 89dd would be a smart call here. But not Ax I didn't say a normal big stack would make this play... I said an loose bigstack would.
-as antes grow, calling ranges should WIDEN not shrink. The bigger the % of the blinds the antes are, the juicier the pot. What SHOULD most greatly influence their decision is the size of their stack, the size of ours.. and the number of people yet to act when it gets to the villain... and the stack sizes behind. I suppose the call range will only be widened if the amount being shoved all in is close to the blinds/antes anyways (i.e shoving last 3700 in with 2000/1000 antes), otherwise average stack's calling range should not be increasing... their shoving range would be. Unless they assume you're stealing, possibly because you've made the move before.
-Lastly- when I shove, I'm fine with a call, with whatever hand I am shoving. I assume i usually get just the blinds and antes, but if i get called and win, I get a double-up plus. That's why I am not shoving worse than what the effective nash equilibrium hands are unless it's a tight table.. and shoving tighter than nash at a loose one. I really don't see how you think people are calling you with crap midway through a tournament or SnG, I would think that if you're stealing you aren't doing it with a hand that you want people to call you down with, otherwise how is it a steal? If you shove with aces and no one calls, is it a steal? You had a legitimately good preflop hand. If you shove with A9s thats a steal, and you should be worried imo if someone calls you down.
Then again, if yo uare playing micros noone has a clue about any of this stuff, so OP should just shove the AK and get called by worse more often than not.. and therefore double up more often than not. Did you think OP was talking about playing 100 dollar buyin SnGs asking this question? Of course he's talking about microstakes.
