Sure this idea has been mooted before.
The Con Move was designed to speed up the games. Really you should
treat EVERY postion as though there was something nasty lurking and
not be given a hint.
Heed Igloo's wise words of wisdom:
"A lot of losses in the lower ranks (myself included) happen because of
missing something."
Everyone who has lost a game has missed something.
But at the lower levels the misses are so obvious that doing a simple
pre-send check would eredicate all those silly one move blunders.
At the lower ranks if they played a sound game, not doing anything but
simply concentrate on not leaving any pieces en prise to a one move bluinder,
they will find their wins ratio will increase by an alarming rate.
Then to be a good chess player all you need to master is the two trick.
(and an opening trap or two).
Look at every undefended piece for you and him and see if there are any tricks on.
King's, Queens and Rooks on the same diagonal/file/rank?
Look for Pins and Skerers.
King, Queens and Rook can be hit by a Knight?
Look for Knight forks.
And CHECK ALL CHECKS.
It's easy. Look at this 1500 player doing the two move trick. Good game.
