This is an subject I have asked about before – of how exactly to adjust to ante free games. I think they are considered very low stakes, maybe even a lowly form of poker and that probably most people on this site don't play them often.

I do play and enjoy them.  I imagine that the way to consider adjusting our play is in a way that combines what we know about late game play (because of the large blinds at those stages leading to larger pots) but also what we know about early game play (because of the absence of antes leading to smaller pots).

The difference first off only begins once the mid game starts and antes would have been introduced.

Once that happens, in the mid game, I open less pots (less than I normally would in the midgame) because it's not worth the risk as much to open into 7-8 players.

Once the late game happens, the size of the blinds does make it more worth opening wider.  So I try to open wider, but not as much wider as usual, because there are still no antes.

Also I try to consider my low to mid stack a tad stronger than I do in a game with antes, because we don't lose as much during each rotation.

That's all I'm really very confident saying, and even that may be faulty.  Hope it helps.

Thanks for the response Andrew.

By saying I consider my low to mid stack “stronger” when without antes, I mean that I consider it less vulnerable, less in the red than when with antes. It could  be described by saying that without antes, my stack has a bigger M and more revolutions to survive.  Therefore I'm less desparate and possess more fold equity against thinking players.

Perfectly open to corrections about that way of thinking 🙂
