Changed blinds structure- what to do?

[PalmiCa]

I am playing at pokernetwork site. Yesterday they changed blids structure.
For the first time I am playing SnG with antes.
What should I do different now?
And blinds structre is slower. For example 20,30, 40,80,120,160,200,250 ( before, 20,30,50,100,150,200,300 ).

Correct me if I am wrong, now with ante in tournament I need to play more agressive at the end, especially if I am short stacked.

typical strategy is to steal blinds with a wider range once the ante's kick in.

Yea, but how much wider?

For example, I was playing really tight until BB= 150 ( My M usually around 9 ), then more and more looser with every level.
But here I have blinds 120 and ante 10, should I play that like B=150 before

Calculate your M for the old and new levels, then you can compare how many chips are in the pot preflop (meaning you should play similarly with similar Ms with or without antes).

You need to adjust your preflop raises a bit when there is ante

I think you should play the same as without antes as long as your M is the same (since M takes antes into consideration)

True in terms of hand ranges, not true in terms of bet sizing (you give your opponents better odds to call if you do not adjust your bet sizes)
