I'm trying to find a better line of play than 'cash three rounds of clubs, play off two top hearts, cross to East in spades, play three more hearts pitching two diamonds and a spade, later ruff West's last spade loser'. As you say that relies on 3-2 clubs (if they split 4-1 even if the singleton is the jack we don't have a fifth heart trick as it can get ruffed, and now we need to rely on a diamond-spade squeeze or the diamond finesse) and hearts being 4-2 or 3-3 or singleton HT. I think that this puts the grand at approximately 47-48% or so - well below the 75% that I normally consider the threshold for wanting to be in grand. What am I missing?
Not so great, as you say.
Not so bad either.
68% clubs 3-2 x 86% hearts coming in is 58%.
Plus other chances as you say.
Say they lead a major. Win in hand,
♣A-Q.
If South has
♣Jxxx, run
♦Q, ruff a diamond, then finish trumps.
East might have had the
♥10, etc.
