These hands are both at MATCHPOINTS.

Scoring: MP

South plays 4S, opponents have been silent. LHO leads the heart 2 (fourth best) to RHO's ace. RHO returns a spade. How do you play the hand?

Scoring: MP

South plays 3NT. LHO leads a heart to RHO's ace. RHO returns a heart, do you pitch a club or a diamond from dummy?

and the result can be plotted on a graph.

Hand 1:

The opening lead seems to be from ♥ Kxxx, but the play works also if the lead was from ♥ Qxxx

Win and trump a ♥ and trump back a ♦, draw trumps and play all your trumps except one, to reach the following 5 card ending:

♦ AQ
♣ AQT

♠ X
♥ JT9
♦ -
♣ X

Exit with a heart. West can either play low or high.
If West plays low East is end played.
If West plays high your ♥s are good

Hand 2:

If you discard a ♣, you have 12 tricks if ♦ break (68%) and 11 if they are 4-1
If ♦ are 5-0 you can still start by playing on clubs after 2 rounds of ♦
If you discard a ♦, you have 12 tricks if either minor breaks and the club finesse wins (45%)

So discarding a ♣ wins whenever ♦ break and the ♣ finesse looses. (34%)
Discarding a ♦ wins whenever ♦ do not break, but ♣ do, and the ♣ finesse wins (11%)

Guess what you should do.

We should read Justin's hidden text?

That's impossible. No one can give more than one hundred percent. By definition that is the most anyone can give.

I thought for a moment that my skill level improved dramatically overnight :unsure:

Before internet age you had a suspicion there are lots of "not-so-smart" people on the planet. Now you even know their names.
