85% of the time I raise 4XBB in any position.

Occasionally I will raise 3XBB with mediocre hands or AA KK.

But I will usually raise 5X or more if there are a lot of limpers or if my table is way too loose. Or if I have a medium pocket pair.

It really depends on your table. What will they call. What won't they call. But keeping it consistent is important.

If you vary your pfr every once in a while, a lot of times you don't even show those hands, so they never get a read on it.
