My humble assessment is 2H fine. 2S questionable, but he felt he had to bid something. 3H unforgiveable. It violates partner trust to bid again, unforced on a pre-empt. 3h doubled looks like penalty to me. Otherwise, he is forcing vulnerable to the 4 level in the direct seat completely blind. That makes no sense to me. 3H redouble truly bizarre. How could an expert redouble a preemptive bidder who rebid his hand. Make the preemptive rebidder suffer the consequences. The run to 4 diamonds ridiculous. Let your partner run to clubs, and then you can correct to diamonds. The double of 4 diamonds is very sound, in context. Obviously there is table confusion, so with trump now decided in your suit, by vulnerable opps, double away!!!!!! The redouble truly foolish. bad to worse to worse to worse. But, misunderstandings happen
