When I started, Michaels was either weak or strong. You were either 7-11 or 16+. With say 12-15 you were supposed to overcall.
These days, is there a trend to ignore strength and use Michaels on a hand like this?
Anyway, partner overcalled 2♥, which I passed for -200. It was some relief to see that 5♣ also fails. Perhaps you would bid over 2♥. 3♦ -- usually played as forcing -- seems a bit rich.
An alternative for East is 2♠ as an "English" style unassuming cue bid, like a takeout double. I like that but most seem to play that as a heart raise.
South opens 1♠
