Background:

We play weak and at the right vul VERY weak jump overcalls over 1♠
We play int-strong jump overcalls over a weak 2♦ and don't change what we do if it's intermediate

What jump overcalls do most people who do something like the above play over a precision 2♣ ?

The hand in question was at even vul, xx, K10x, AKQxxxx, x

The only intermediate jump over calls I have played are against Two over One 1♣ and 1♦ opening bids. I guess, I'd have some questions for you if I were to provide any feedback. Are your jump overcalls intended to be single suited? What do you do with a 16 HCP hand with 2 suits? Double?

If you already have an agreement as to what you do over intermediate 2D openers, why would you do anything different over intermediate 2C?

[Tramticket]

A 2C opening is well defined within a narrow range. In these circumstances a preempt seems to be less useful as your opponents will be well placed to judge what to do.

Well we play weak over a precision spade and 1N which are the openers below, and when I asked partner what he thought, he (who actually plays precision more often than I do) said that a weak 3♦ overcall was something that was a useful weapon, I wasn't sure.

To Kingcovert: The jumps are single suited, I suspect 3♣ would be both majors, a 16 count with diamonds and a major if not good enough for 4♦ leaping michaels would just be overcalled in the major

I suspect that it might matter whether opps are playing 2♣ as 6+ or as 5+. After all, Precision players who play 2♣ as 6+ are giving up better constructive bidding(*) for better ability to handle competition.

Of course you probably don't want to switch depending on the difference, but it might matter which is more prevalent in your area.

(*) Playing 6+, the (41)35 hands are a bit hard to handle, whereas "everyone" knows that, if the opps don't jump in, the Berkowitz-Cohen relays handle all the possibilities over 5+ 2♣ very well.

++++++++++++++++++++++
On the given hand I overcall 2♦. Over an opponent's weak 2 or Precision 2♣, the kind of structure I like:
- X = T/O
- 2♦/2♥/2♠ = NAT 5+ cards.
- 2NT = NAT 16-18 HCP.
- 3♣ = ART 5+ ♥ 5+ ♠.
- 3♦/3♥/3♠ = NAT F/G Sets suit. Invites cues.
- 3N = NAT often based on a long ♦ suit.
- 4♣ = ART 5+ ♦ 5+ ♥.
- 4♦ = ART 5+ ♦ 5+ ♠.

I like the two-way Leaping Michaels, but am unsure about the GF natural JS over an intermediate bid. It is interesting.
