Hi Dann, no human would play a4 even if a4 is the shortest way to mate. It is a table base win. A simple human win is Nf3 or Ne4 and if black plays Kxc4 white answers Nd2 followed by Nb1 and the win is clear even for a weak player. Greetings from Germany BTW do you really believe Germany is like Libya or Cuba? We have American neighbors and a very good relationship Bernhard On February 07, 2003 at 03:32:11, Dann Corbit wrote: >Can't find the original post. > >Someone said Ne3, Nf3 were the best moves.
