Pot odds rule.
if you open 6BB pot is now 12 BB.
The big blind already has 1.5 BB in the pot, so needs to put in 4.5 to call, which gives him pot odds of 12:4.5 or 2.6:1

So any hand with 28% equity or greater vs your opening range is an OK call.

I was a bit surprised to find that this is any two cards...

Equity     Win     Tie
MP2    66.51%  65.66%   0.85% { 66+, A8s+, KTs+, QTs+, JTs, ATo+, KJo+ }
BU     33.49%  32.63%   0.85% { random }

So I must have done something wrong.
Most probably in assuming you should open 6x.
Try the same for 8x -- the idea is to restrict BBs opening range.

All the best,

Yeah, I kinda confused myself, too
I'll see if there are some math-adept mods (or others) that can help here.

Peace,

Oh boy, I don't really play ante games and haven't studied these much.

The big blind already has 1.5 BB in the pot, so needs to put in 4.5 to call, which gives him pot odds of 12:4.5 or 2.6:1
Are you sure it works like this? I thought the antes go straight in the middle of the table and when BB has to make the call, he still has to call 5bb, so he would have only 1bb invested?

Then I'm not sure how much we really should start increasing our open sizes. Trying to make villains odds worse increases the pot a lot, which makes stack to pot ratio smaller, which then again affects our range a lot. I would instead just play a lot looser and dominate villains postflop
Also, if you are playing against recreationals they might not realize how good odds they have and they might overfold a lot vs smaller sizings.
