I would like to hear opinions from people who have at least some experience from playing deep ante tables.

Today I noticed that I had deep ante tables filtered out. From curiosity I choose only them this time and went for a first session.
Because is allways better to win 250bbs rather then just 100... but... it is probably not going to happen so often to just stack off like that and I even admit having weird feeling squeezing AA OOP and cbeting on dry Qhigh board.

Sure it is inexperience, but that feeling I will run to sets so deep, and it is going to happen in the future, arose so many questions/thoughts in my mind right now, not only about this particular spot, but about whole preflop and postflop ranges and all kinds of lines possible.

I will write some of them, and probably add some later.
And anybody can do so too, so hopefully we will have fruitful discussion.

It is not going to be well organized and structured, just quick first thoughts and impresions.

The first thing we can notice, is that we are deep and there is an ante.

1. Do we want to wider our ranges to steal the extra money more often. If yes, to what extent?
Wider only our CO and BU range, or even UTG and MP?
Or it doesnt matter so much (very likely yes ) and we can keep our standard 100bb ranges with marginal changes.

2.
I open 2x on the BTN and CO at 100bb tables. Should I increas my sizing to 3x and keep my wider range?
Saw bigger 3bets and opening sizes. Like 4x also on CO and BU. Is it standard at these tables or only just at lowstakes from unexperienced players? Do not mean some supertransparent bigger 3bet or opening sizes with AA from fish.

3.
Always call 3bets (IP and OOP) with all pocket pairs? Or it is going to cost us a lot, so just do it with 77+ for example.

4.
Is there more value in flating all suited Ax hands IP and OOP or 3betting some of them. I understand that it is very highly opponent dependent, and I dont await, that you will build an exact range for me, but I would be very happy for little insight to your thinking and strategy in general.
Same for suited connectors.
