If after removing straights and flushes, if hand X beats hand
Y under normal poker rules, the hand Y beats hand X under
razz.
There should *never* be a case where one hand wins over
another in both normal poker rules and razz (after removing
straights and flushes).
Therefore, 6s full of 5s loses 4s full of 8s in razz and
likewise by the same logic 6s and 5s beat 4s and 8s in razz.
4s and 8s should definately *NOT* beat 6s and 5s in both
7-card stud and razz. If one hand wins in 7-card stud, the
other hand wins in razz. It is that simple.
