I count one time this week I won with JTs by hitting a Flush, but I wouldn't probably remember if it wasn't so recent - maybe it happened even more often and I just didn't take note of it?
I added JTs to this thread of mine:

because Alec Torelli once said that JTs ("especially in diamonds") was always his favorite hand when he was starting out with poker because he felt like he would always win "more pots than he should" with it lol. Objectively speaking, it isn't the best hand preflop at all - but it does have post-flop potential: I will say that
Yes, there is a difference between "liking a hand" and playing it all the time from any position. I'm pretty sure Doyle likes T2, but I know even he wouldn't play it everytime from any position. But then again, I like AA and will usually be playing that from any position
