The explanation said that the 4C bid denied a major suit ace. Thinking that slam might be a bad idea with two aces missing and the opening leader aware of the fact, I chose not to bid slam. Silly me. I suggest that the explanation be revised. I understand that the explanations are sometimes not completely accurate (but close enough), but this one is too egregious (not even close). Only four bidders on this hand used this exact sequence. Three stayed out of slam. One (maybe did not read the explanation) bid it anyway.
