Good evening TPE,

I have a general question after some situations came up in recent sessions.

I know that in order to get a good idea of how a player plays we need a good large sample size.  Probably several hundred hands to get basic information, thousands of hands to get a full picture.  So I understand that if we only have 30 hands on a player, we must be careful not to assume too much (if anything) about that player's ranges and tendencies.

But what happens when it's getting down to the final few tables, and someone who you haven't seen before and who's been at another table all game sits next to you and seems to open every unopened pot?  I imagine we can't make a judgement after just one orbit that this player is opening wide (as running good happens to everyone) and it certainly isn't worth a hero call to find out. 

But what about after two orbits, in a situation where blinds are rising and the average stack is just 15BB? 

In other words, if you are getting short, say 10-15BB, and said player enters and starts opening every unopened pot, about how long do you keep folding until you start considering calling with weaker holdings?  Do you try never to do this?  Will you start calling wide after just 5 opens in a row?

I realize this may be difficult to answer since it's probably a sliding scale that depends on hero posiiton, villain position, stack dynamics and the whole bit.  So I welcome any response on this subject taken from any perspective.

Thanks for reading.
