If a red house is made of red bricks, and a blue house is made of blue bricks, what is a greenhouse made of?

What do you put in a toaster?

Say “silk” three times: silk, silk, silk. Spell it: s-i-l-k. Now, what do cows drink?

If you answered glass, bread and water (not green bricks, toast and milk), you may be more alert than most. As a further test, plan the play at today’s six spades when West leads the queen of diamonds.

North improvised a strength-showing “reverse” to two hearts at his second turn. His bid was safe; if South raised, he would have five spades, and North could -- and did -- return to spades.

South took the ace of diamonds and wanted to ruff his two diamond losers in dummy. He ruffed one with the ten, cashed the ace of trumps, ruffed a club and ruffed a diamond with the king. Declarer then came to his queen of hearts and led the jack of trumps. East took the queen and led another diamond. South ruffed and drew the missing trump -- and had none left. The hearts were blocked, and he lost another trick at the end.

South’s thoughts were inefficient. To overcome the blockages, he ruffs the first diamond with dummy’s king, ruffs a club and ruffs a diamond with the ace. South then leads the ten of trumps. If East wins and forces with a diamond, South can ruff, draw trumps and run the hearts.

A trump opening lead would beat six spades.
