1) North is 100% responsible for missing game. Second double is unclear, it could be penalty (1st dbl shows 3 suits) or a little extra for further competitive. 2) 2S by North is not forcing, imo. South's free 1NT over opp's 1H had showed his hand. I would cue-bid 2D and then introduce S later. 3) After opp's opening (and responses), it is difficult to find the slam. It is not a good slam anyway.
