In Bridge Master on BBO, the solution sometimes seems like 'resulting'.
I am working through Bridgemaster and have gotten to the Advanced hands. I try to understand the what hints the declarer might get to choose a specific line of play and, tbh, have benefited a great deal in my hand play.
However I've reached what seems like a block.
Hands 23 and 25 are virtually identical in distribution and contract (6S), there are no competing bids but the winning lines of play suggested in the solutions is slightly different.
The 'declarer' in hand 23 is cautious about playing the 3 winning tricks of the outside suit while the 'declarer' in hand 25 seems quite confident that the 3 tricks in the outside suit are safe to play before drawing trump.
The only obvious difference is that the opening lead in 23 is a KH, while the lead in 25 is a trump.
There is nothing in the bidding to indicate that the Kh is a singleton and not from KQH.
What am I missing that the phantom declarer sees that affects the declarers decision on the distribution of the Ds?
TIA
