    Here are the answers to problem #1 posted to the net on Dec. 23 '83.
IMPORTANT NOTE: Please note that, as suggested, I have inverted the numbers
on the left hand side. Now here is the problem as posted....
============================================================================
    There will be three problems today. All are taken from a Nihon Kiin 
publication and are ment for levels 10 kyu and above. In all three
problems black is to play first. Question... What is the outcome in each?
Can black kill? Is white alive? Seki? You decide.
