You have to punish him on 4th because, even if you make your
98 on 5th, if they catch a wheel draw they can bet/raise you
for value on 5th.

Also I'm sure they are just testing you on 4th as to how good
your "stealing" hand is. Another raise on 4th and a bet on
5th would almost certainly have taken it down in this case.
