I said i am trying to make 2

♣ 8 at first trick, i can take it in hand and play
♦K right away.
Still i doubt that makes my line better.
I think we may try to show that the "Diamond line" is inferior to the "Heart line" this way :
- if you take the Jack of clubs at trick 1 and run the
♦King, you go down if East takes this (he returns a Spade) ;
HENCE the Diamond line needs
♦Ace at least in West's Hand (42% using vacant places : West has 5+ Clubs) + nothing nasty in
♠/
♥ ;
HENCE Diamond line is inferior to 40%.
- the Heart line works everytime Hearts and Spades behave (that's also around 42% using basic calculation) and also works with some 4-1 and 5-2 breaks in the Majors.
HENCE Heart line is clearly superior to 40% (probably superior to 50%).
Those are really vague approximations, but imo it shows that it's certainly better to ruff a Heart at trick 2.
