This light to jump? Less than an opener for 1s?? I think this is too aggressive/restrictive.
I think this leaves too much ground to cover with stronger hands, especially if opener has enough to bid again. I'd expect jump to 2s to be more like 15-17/14-16, and 1S range to be something like 8-15/16/17 depending on agreements. Double then bid suit should be reserved for hands stronger than this that are afraid of 1s getting passed out when you have game on power. When you need some sort of fit and a 9+ count for game, partner won't be passing 1S, and forcing yourself to double first just because you have a full opener leaves you in awkward situations at high levels after auctions like (1H)-p-(p)-x;(2H)-3D-(P)-? Do you really want to bid 3s here forcing on a 13 count?
It is not really that aggressive/restrictive. Remember you're taking some inferences from the auction. If you balance on a 6 count at 1
♠, RHO probably has less than 5, if LHO (opener) has a decent 16 count, that leaves roughly 13+ for partner to have sitting behind opener. Does that mean you balance with every 6 count? No, especially not if you are VUL. But if you had something like
♠ AK10xx
♥ xx
♦ xxx
♣ xxx, I'd doubt you'd find many people who wouldn't balance 1
♠.
At the 2 level, such as a non-jump 2 of a minor reopen, needs to be a bit stronger more like a 9/10 minimum. Corresponding balancing bids also need to be a bit stronger. So a jump to 3 of a minor ought to be more like a good 14/15 with a good 6 card suit.
After (1H)-p-(p)-x;(2H)-3D-(P)-?, if you're bidding 3
♠, you're showing the 16+ strong overcall and it's non-forcing for partner. If you have the light shapely double, you're passing 3
♦. If you have an off shape double with a doubleton
♦, you're probably passing 3
♦ also. In most cases, you need chunky normal takeout double to move.
Mostly, balancing is geared toward fighting for the part scores.
BTW, the Pavlicek link identified in an earlier post connects to a write up very similar to what I've covered. as usual, it's excellent.
