I open 2D to show a 3 suited hand, alerted and explained. When partner then bids 2H to Play, should I alert his bid (as opponents may think 2H is a one round force)? Thank you

Depends partly upon the regulations of your RA: over here, you would not be expected to alert 2H if it shows hearts and neither of your bids are forcing.
But if opener has important inferences from responses not made (2NT forcing enquiry, or whatever) then we would expect you to alert those, although I gather ACBL is not big on that.

Yes, I am in ACBL land and 2NT is the response when partner wants to make further inquiry. Is 2D forcing? If partner has 6 Diamonds, he could pass, otherwise I would expect a bid, but it isn't 100 percent forcing. So, a suit bid infers that my partner wants to play it there unless that is my shortness. Maybe an ACBL director will pipe in. Thanks!

Unless you play a special version of this 2D "Mini-Roman" convention, 2D is an artificial but non-forcing opening bid. Partner might hold KQJxxx of diamonds and out and pass 2D.

Because the 2H bid is "pass or correct" and is often made with only THREE hearts, I think you should alert responder's 2H bid.

That’s a good point. Alert, may only have 3

From the ACBL Alert Procedure:

"Natural Bids: Alert...

Responses to Opening Bids

1. By an unpassed hand, and after an Opening suit bid and an opponent’s pass or overcall,
a Non-Forcing new suit bid at the cheapest level (unless that bid is at the level of game
or higher)."

So, over a Precision (guaranteed short diamonds) 2♦ opener, Alert it (non-forcing, Natural because "intending to play"). Note: those of you playing Flannery better do it too, and I don't remember the last one who did.

Continuing:

"Artificial Bids: Do not Alert:

1. [2NT after a weak 2]
2. [Stayman after 1NT or a sequence of Artificial Bids leading to 1NT]
3. 2♦ response to a Strong or Very Strong Artificial 2♣ Opening Bid."

Pass-or-correct calls are not defined Natural (there's a blurry line there, in the meaning of "suggests the contract bid". But consensus seems to be "suggests the contract bid, unless it's *not* your suit" doesn't count.) and aren't an exception, so Alert if it's mini-Roman.

What does "To play" mean? Does this mean partner will pass with 4♠0♥5♦4♣? If so, then my guess is no alert needed.
However if he then bids anything in search of a better fit, then it would require an alert and if asked for explanation "Pass or correct" would be more appropriate.
