South is in 7H and the CK is lead. This appears in the current edition of
"Bridge" and I can't see how to cope with the H & D blockages. Can anyone
improve on quietly going one down?

GIB can. He reports after 1/8 sec (5376 nodes) that South can indeed
take 13 tricks after the CK lead.

Great - GIB spins through 5K nodes then announces "Yup, it's trivial".
Too much like too many of my professors.

ps - didn't this problem get posted just a couple weeks ago? Is it
an epidemic?

Win the CA, pitching a diamond from dummy. Heart to the board, ruff a
spade. Heart to the board, ruff a spade. Last heart to the board. Pull
the last trump and cash the SA, pitching diamonds from hand. Now the dummy
is all good diamonds.

My double-dummy bridge evaluator took .27 seconds to expand 8404 nodes
to produce the playing tree. It shows that
South wins opening lead with AC, pitching small D from dummy
goes to dummy with trump
cashes AS, pitching AD
ruffs QS
returns to dummy with trump
ruffs 7S
goes to dummy with declarer's last trump
cashes dummy's last trump, pitching KD
dummy is high

Maybe GIB has seen this problem as many times as the rest of us.)

Win in hand having thrown a diamond. Cross in hearts, ruff a spade, cross in
hearts, ruff a spade, cross in hearts, draw the last trump and cash the Ace of
spades throwing the AK of diamonds.

This is the third time this problem has appeared on rgb. So it must be
a good one.

Does this mean you want someone to tell you how to make 7H on KC lead?
