Is this something new in (under) the hood?
This happened to another player in an ACBL robot IMP's tournament this morning.
I cannot find any reference to Truscott - or his friend Jordan - being used after opening 1 minor.

Yes, Truscott is a common agreement over minors also. Truscott claimed this sequence as his in his bidding dictionary book with reference to a prior Bridge World article so I'm inclined to believe him.

But it's up to partnership agreement. Personally I don't think this is theoretically best, as over a minor raise you frequently want to play in 3nt (as opposed to when the major is raised, when you almost never play in 3nt), and if 2nt bidder has a distributional limit raise this can wrong-side stoppers in a critical suit. With my partners who can stand the memory load, I prefer to play 2nt as natural invitational, and use jump-shift in the other minor as the limit-or-better raise (aka criss-cross raise after double). But I have a bunch of partners who have limited memory so still play 2nt LR+ with them.

"Unfortunate" on this board overbid. Flat 18 opposite 10-11 is 28-29 range, not quite enough to seriously consider looking for slam. Need more shape for that. It should be an obvious 3nt this hand.

Thanks - Mr Google failed to come up with that possibility.
I had a somewhat easier time of it.

Opposite a passed hand slam is likely poor

Opening a 15-17 NT on an 18 count with all aces and kings and two tens to boot isn't a good idea either, in the long run. You'll miss a lot of good games and the occasional slam (opposite an unpassed hand). "Unfortunate" was overbidding by about a K, you were underbidding by about a Q. You just happened to catch a responder where your underbid turned out to be in the range where it didn't end up mattering.

Well, I play flip-flop (and hope to remember it), for specifically this hand, where I want opener to play 3NT and doubler to be on lead. But apart from that, yes, it's common to the point of being something I would expect opposite a random partner.

The other brother you might look for is "Dormer". I *think* originally Dormer was for the minors, Trustcott was majors; but I wasn't playing bridge at that time, and it doesn't matter anyway (except to purists).

With my regular partner 2NT is always a raise over all 4 suits. Jacoby by an un-passed hand against silent opponents, Truscott (or whoever) by a passed hand or after competition. But we do play 4cM and 4cm.
