Playing 2/1 and following the believers of not opening 2♣ with a two-suited hand, the bidding went as follows:
West. . . North . . . East . . . South
Pass . . . Pass . . . .Pass . . . 1S
Pass . . . 1NT . . . . 2H . . . . . ?
If East would have passed, 3♦ would be an easy 100% forcing bid.
However, after the 2♥ from East, is 3♦ still regarded as 100% forcing?
If not, what is a 100% forcing bid?
