river raises 2

Players seem to make raises with all sorts of hands.
They include no pair, one pair, two pair, set, and
better hands. Many player either don't understand
coordinated boards or just have no fear.

Calling strategy. On a board with no pair, four
to a flush or four straight, two pair is a must call
against a river raise. Against frequent raisers call
with top pair. You must to very sure before you can
fold a set or straight.
Repeat. This strategy refers to fix limit, not no
limit.
