Like most others, I don’t like W opening in 3rd seat with the flat 11 HCP hand. That said, it is not a serious error, but a matter of style. I take E’s double to mean 10+ HCP, 4♠︎, which rather accurately describes the hand. W’s 2♠︎ bid is in error, because he has a more descriptive bid of his hand. From my perspective 2NT would describe the hand — and he would not lose out on the ♠︎ bid if P had 5♠︎. (P has the 3♣︎ checkbook bid available to ask for 3♠︎) If one is going to open a light hand, he must be willing to continue to bid it — not overbid it, but bid it as if the opening was correct! 2♠︎ miscommunicates the shape of the hand to p. I find no fault with E’s 3♠︎ bid, he has 4 pieces and 11HCP. N has shown a weak bid, so E could incorrectly assume that P has a full opener…in such cases it would be error not to support p’s bid. If W is to open 1♦︎, I think the bidding should go: 1♦︎-2♥︎-X-p-2NT-p-3♦︎-p-p-p In sum, the fault lies not in the stars, or in E's bidding but in W's continual misrepresentation of his hand (first in opening then in 2♠)
