With a part score of 60 to 0 (neither side vulnerable), I dealt and bid a "strong" 1NT with:
(s) QT3 (h) KQJ8 (d) KJ93 (c) K5.
"West," to my left, overcalled 2 clubs. Our respective partners passed to me.
I doubled (for takeout). West rebid 2 diamonds, all passed, and we set them 3 undoubled.
Partner had something like: (s) xxxx (h) xxxx (d) xx (c) Qxx, and might have bid (2 clubs) "garbage Stayman" if West hadn't. My takeout double was meant to produce this effect, and probably a two hearts contract, except that West took me out.
Did West effectively "rescue" me by overcalling, meaning that I should have kept silent? Or was it right to double to try to force partner to bid in this situation, risking a downed contract, to deprive the opponents of their (likely) 40 point part score?
