2) You are not forced to go allin: you have the options either to fold preflop or just call BB (and BB is 20% of maximum buyin at those tables). So there is a bit of skill involved (you should know what range of hole cards have >50% equity against another random couple of cards). So I can definitely state you are wrong on this particular opinion.
I could be wrong here, as it is difficult to follow along all of these quotes when you drink as much as I do ... but I am pretty sure the original guy was referring to a 1bb table, and if that is the case, there isn't much fold opportunity until stacks get built up a bit. On those tables, BB is the full buyin, and SB is .01 less than that.
No mate,
I'm pretty sure, but can't check it now because swc is down, that they are 1-1 chips (not BB) tables meaning that either minbuyin and max buyin are set at 1 chip but BB is 0.20 chips and SB is 0.1 chips.
And so on with 2-2 tables (BB 0.40) etc etc
