What about saying?:
TBL1.CATEGORY = TBL2.CATEGORY
If your indexes include this and the other columns which cause the tables
to be related, one or both of them stand a pretty good chance of evaluating
to the lowest-cost method to join the tables. Forcing a query to use an
index outside of it being the cheapest path is rarely productive.
