Short Handed No Limit

[cmillard]

I play a 3-4 person No Limit game every day for about an hour just for fun. I am getting killed by two very aggressive players. It is .25 and .50 blinds, no one usually has more than $20.00 invested. Again, it's not a lot of money and it's just something we do at lunch......but I can't stand losing!! I seem to play very well at a 8-10 person table, but this is blowing my mind. I need some tips for playing aggresive people short handed.
Thanks
