J9 and J10 are both poor hands, and you should very rarely play them...
The reason J10 is a fave of the pros, is that it is a "nut chasing hand". If you have a straight with J10, it will be the nuts (on a non-paired/3 flushing board)... and if you flop a straight draw, it will be the nut straight draw... and pros are good enough to not get attached to top pair, weak kicker - so it can be a very profitable hand, and is unlikely to lose a lot, as they won't chase with poor odds.

it depends on many factors: is it cash game, sng, mtt; what stage of sng/mtt - early , middle, bubble...what kind of opposition you're against- say your table is full of "all-in" morons, then j9/j10 is not the best hand to play...u know yourself that u can with with any hand, so just move all in and pray

Rarely play j9 suited or not and J10 more likely, but only when I feel it if you know what I mean. Just seems to bite ya to often if you play these hands on any type of a regular basis. I also don't care for a K,9.
