I have recently put some bridge puzzles on the whiteboard, all these puzzles where composed by Richard Pavlicek.
Here is a link to his web site which is very good and worth a visit:
http://www.rpbridge.net
the puzzles and their answers can be found at:
" up for promotion " http://www.rpbridge.net/7e93.htm
" the tell tale double" http://www.rpbridge.net/7f35.htm
" Capture the queen" http://www.rpbridge.net/7f12.htm
Enjoy!
