ahem *cough* ok here goes....
Firstly I believe you had 6 peeps to act after you. Now I know you have a hand that'll stand up x times out of x but it was your tourney life. The bet was about 6 x BB so was isolating in itself without you adding to it and if anyone came in after you they had to be ahead of you. If they went over the top you could then fold, unless you wanted to race AK, (which is a doubtful holding given the initial raise). A smooth call behind you would raise alarm bells but at least you would get to see a flop and take it from there.
But your all in has no upside but lots of downside. As I said, isolation was already achieved and all that could happen was that you were gonna get caught with your pants down if someone behind you woke up with AA/KK.
You had a decent stack and I don't think you needed to get yourself where you were on that hand - I believe I told you that you were f*cked before the cards went over.
*edit* you say you were one from CO...really?....I'm sure I was MP and you acted before me....you had to be in fact coz that was the whole basis of the ruck. Maybe I should drink less.
Im not sure what the standard is like in this tournament but you make it sound like everyone behind iron is going to understand what is going on. In my experience online/live 6bb raises don't on their own isolate at all, iron calling makes the pot quite big and live players love what they call "value" and will limp behind with all kinds of stuff here aq,aj,a10,kq, pairs and thats the tight ones.
Your going to fold to a shove right, ok whats a reasonable shoving range behind here ak,jj+ looks kind of tight and right. Once we have limped behind and a guy shoves for avg 11k assume he is the button. In the pot already is 19.2k (3.8+3.8+11+200+400) so iron will have to call 7.2k to win 19.2k so only needs to 27% to win the hand to justify calling.
Iron is 47% against the range i have assigned, 39% against ak,aa,kk. Only not getting odds against purely aa,kk and that is not a realistic range for small buyin live tourney player IMO.
As said before isolating to shove here looks best.
