bet sizing
When there are limpers in front of Hero and Hero has pocket Aces, Kings or any time Hero wants to raise with limpers, a good rule of thumb is, 3 x BB plus one BB for every limper. so that would be BB X 7 or 630 chips. This makes the
odds for any one to call not so good, and they'll need a strong hand to continue, getting out the speculative hands that could out draw you.
Is it wrong to shove pocket Aces in early stages of an MMT, I would have to say yes it is not a prudent play. Hero still has an M of 29 or 47.75 BB's. Hero may be a short stack relative to the other stacks but not according to the Blinds. The table looks loose and without taking a chance with Hero's tournament life, Hero could have seen a flop with a proper raise or still won a nice pot of 6+ BB uncontested.
Pocket Aces against a single opponent have great odds to win, like 80% give or take, or they win ~8 times out of 10. For every opponent more than one, Pocket Aces chances to win drop dramatically. If all players that limped decided to call Aces only win about 40% of the time, that's only 4 times out of 10. Against 10 players Pocket Aces only have about 30% chance to win or they win 3 times out of 10.
