I was in the last 12 of a 45 player online tournament with a $1.50 buy in, NL Texas holdem. I was switched to a new table and every single round someone would go all in pre-flop, this continued for about 20 or so hands.
In the first couple of hands I lost a few chips as I did a 2x BB raise but folded after someone went all in. I was starting to get fairly short stacked due to the blinds and ante.
I wasn't getting any good hands so folding and then got an AQ so called an all in and lost most of my stack, ended up going all in a few hands later as I didn't have enough to cover the BB and went out.
What kind of strategy can I used when every round someone is going all in like this?
