Seconding the Drury recommendation -- you need to have a way to slow partner down when you open these hands (and seconding everyone else that you need to open these hands at matchpoints).

I don't think 1H is indefensible here as an opening. Slam is not out of the picture, e.g. is 50-50 if partner has Ace of hearts and Ace of clubs. I would probably open 4H though because it's matchpoints and you're vulnerable, which means missing a thin slam isn't a catastrophe (whereas letting the opponents find a spade fit might be).

I also would not double. In addition to the concern you raised about partner bidding too high, this hand has poor defensive strength and partner might erroneously penalize a "sacrifice."

Just a quick additional answer -- a hand plays very quickly in bridge; rarely more than 5 minutes after the auction. In a typical evening session with 28 boards, you'll be dummy roughly 7 times, and it's a nice time to relax the brain a bit.

+1. I'd add that at matchpoints it's a decent opening almost regardless of where the points are distributed.

@GendoIkari the linked questions asks if you can move into the safety zone (you can't -- that's not backwards); this asks if you can move to just outside it (you can)

Adventures that just came out, I'd put as even more complex than Dark Ages, and a ton of fun.

+1. clarification in case OP is relatively new to bridge: by "fast rebid" you mean, "at the next round of bidding." of course the tempo, slow or fast, of the rebid itself, cannot legally be taken into account by partner!

Why was this downvoted?

@Tom77 right but the point of the response is what we can infer from partner's choice to pass and not double.
