The answer is "usually, but it depends".
Here are the factors I take into consideration:
<ul type="square">[*]How many players are left to act behind me, and are any of them likely to reraise?[*]How many other players are also tied to the pot?[*]Is my hand one that thrives on implied odds? (If so, be more inclined to call)[*]Is my hand likely dominated?[*]What are the raising standards of the raiser?[*]Can I get it heads-up with the raiser by re-raising, and would I want to?[/list]
