♣9 led. How do you pick suits?
Auction :
East South West North
1♣-Pa-3♣*-X;
3♠-Pa-4♠-ap.
*3♣ Inverted
The apriori odds are not how to analyze the likelihood of where the cards are.
E opened the bidding 1C in 1st.
=they do not have a 5+ card suit higher ranking than
♣'s
=they rate to have 2+ QT.
W made a Inverted Minor preemptive raise at Unfavorable.
=they rate to have 0-3
♥'s
=they rate to have 4+
♣ and be shapely or 5+
♣'s if they are not.
=they have 4-7 HCP.
=We have 19. That means E has 21-(4...7)= 14-17 HCP.
=Since 14-17 HCP mostly overlaps Their 1N Opening range, Opener rates to be shapely.
Until we start to get a count on E's points and shape and can further constrain their holdings, E is something ~4x more likely to hold any of (SK, HA, DA, DK) and ~3x more likely to hold any of (SQ, CQ, missing J's).
Apriori, We have 4 losers. There is nothing We can do about losing the
♥A and
♦A. Therefore trumps must be split honors or both honors in E's hand.
Nige's line is pretty good. Can we improve it? Hmmm.
The've already played 2
♣'s. if
♣'s are 5+5, They can only play them 3x more.
(Better would be if
♣'s are 6+4 or 7+3 with E holding all the critical non-
♣ cards.)
If cards are where We need them and we Time this right, We have a shot.
=Win CA.
=Take S hook.
a= SJ holds and both followed, bang down the SA.
b= W wins SK or SQ, returns a
♣, we ruff, then play SA.
=play H9 from hand, intending to run it if not covered.
a= if 9 holds, We just got lucky.
b= if E wins HA, cashes
♠, plays
♣, We ruff with last trump, play
♥'s from top, hook
♦Q, play
♦
c= if E wins HJ, we're going Down. A lot.
The goal is to leave Them with a high trump and establish
♥'s as force.
