As dealer I see: ♠AKxxxx ♥x ♦xxxxxx I know rule of 20 says I can open the hand in first seat, but I opted to pass, see what partner bid. Auction went P-P-1♦-4♥ At that point I was torn on whether to bid spades, but knowing partner had less than four but guaranteed three diamonds I bid 5. a) am I right to not open the hand and see what fit I had with partner? b) RHO had ♥AKTxxxxx as it turns out, and I knew they weren't a flaky bidder Five diamonds made. For future though if I'm not facing that jump bid from opps, am I best to open or pass as I did? Thanks
