Tournament HU

At what point in a tournament at HU does it become the correct decision to go AI every hand when you are HU? I know when your opponent is down to 2x the blinds it is correct, but how far can you take that? Only out to 3? 4? Are there any other variables to take into consideration?

'Every hand' is the problem with your question. As your stack gets bigger, you should be exerting more and more pressure. Not in huge numbers, but enough so that your villain feels uncomfortable. Seldom would you want to check your villains bb for example, you either fold it or raise it.

Is there a chart somewhere with hand equities against random hands? With this it'd be pretty easy to figure out using pokerstove the exact point assuming villain plays perfectly but I don't feel like checking every individual hand on pokerstove to find out plus someone's probably done it before me. In practice though people fold too much I've found so you can probably push wider than is profitable against an opponent playing perfectly. I start shoving ATC at like 6-7 BBs but at ~10 I start pushing an extremely wide range.

10bb is the pro norm, at least is what they say in the books i have read. The range of hands is wide open at the 10bb. myself i think about every hand before i make a decision no matter what the situation is and then go with my gut, on line that is about all u have, if u have a tracker or something like that that might help but in that situation but less than 10bb it is pretty much anything u can get in the middle with. Hope that helps and see u on the felts.
