I don't know if this was addressed in the gigabet stack size thread...

I don't think a 49/51 is what's being referred to. If you're talking about things that close then switching a single suit of the cards will shift you from being a dog to a favorite, it's realistically impossible to know if you're the 49 or the 51. This is just a neutral cEV play for all intents and purposes.

Plus, why wouldn't you take it against the 10? You'd have 30k and you can threaten elimination to anyone at the table while still having 10k chips left over if you make a wrong move, and since 4 others also have 10k you're not that bad off.

And I thought you were supposed to avoid close gambles with other bigstacks later in the tournaments anyway. Most of the examples of the play deal with you having more chips than the guy you're going up against but having enough left over to still be a reasonable force if you lose.
