Either the federal server that deals hands is sensitive to solar activity or probability does not work quite the way we expect, but these combinations of a rock crusher opposite a weak but unbalanced hand just keep on coming.

Here's one that caused havoc in yesterday's national sim.
Let's start with just the rock crusher, assuming partner passed (we can discuss that later if necessary).
Assume that partner does not have a well-honoured 5+ card suit if that allows you to progress significantly.

Your opening bid and plan for rebids?

[mw64ahw]

Playing reverse Kokish relay/'birthtright'
2♣ - 2♦ waiting
2♥ 20-21 or ♥s - 2♠ assuming no relay break with a Bust hand.
3♣ you can play as natural, but I also play as showing exactly 5♥
or
3♥ if you use a Grue switch

2 C
Rebid H at cheapest level

I have the same ideas as the rest. Hoping that "cheapest level" isn't 5...(actually, mostly hoping it's not going to go p-p-2♣-2♠; p (values)-3♠. I don't actually *expect* 4. And frankly, I'm not sure I am bidding hearts at the 5 level if they do. I've got a minimum, and no real length (although I guarantee we have a fit somewhere). I might just suggest taking the points.)
