... I can say for sure that reverse jump 3♥ must be forcing a round.
So I think 3♥ should be a forcing bid, but its explanations don't say that.
If South had a hand that could force to game opposite a 0-count, he would have opened 2
♣; failing to do so limits his hand to 22 total points. Therefore, 3
♥ cannot be forcing.
I agree with the human Souths who opened this hand 2
♣, although I know a lot of players don't like to do that with a two-suiter. GIB doesn't open 2
♣ because he counts his hand as 22 total points and won't open 2
♣ unless he either has 23+ total points or intends to rebid 2N showing 22-24 HCP.
