    One of the reasons why in the pre database days you got a lot of
    primer books using the same examples to put across a point.
    was perhaps the authors were a tad lazy, but let's say you wanted to
    show a Queen check picking up a loose piece for example a Rook on a8

    You are not going to flick through 100's of magazines or books in the
    hope of finding one. You would use one you know exists in another book.

    Nowadays far easier to fire up a DB. Look for this position.


    Add on the Exclude Board nothing on f5, g6, d5,c6, ,b7 and off you go.

    Such a search (I did one a minute ago to test it) brought up this game..

    Uhlmann - Baumbach, DDR-Championship 1964. (see below)

    A wonderful instructive find. Here White to move.


    22. Bd5+ cxd5

    Not a blunder, Black knew what he was doing.

    23. Qxd5+ Kh7


    And if White takes the a8 Rook Black plays Bc6 hitting the Queen and
    then Qf3. White has to go for the draw with Qb8-Qb1+ -Qb8+-Qb1+.

    Beautiful, however Uhlmann spotted that shot and slipped in 24. Qe4+


    Now Black cannot let the a8 Rook drop with check so Black
    has to play 24...g6 when the coming Bc6 does not gain a
    tempo as White has Qxa7+ or 24...Qg6 (as played) when after...

    24..Qg6 25. Qxa8 Bc6 26.Qc8


    Black has no Qf3 and as you can see resigned a few moves later.

    Zwischenzugs , perpetuals, mating patterns, traps, forks, pins...

    All that from one game, I have a demo coming up in a few days I'll
    use this. The chances of me finding it from a 1964 bulletin were zilch.

    Chess Databases are the best thing since............
    what did we say before sliced bread was invented?

    Sometimes the bread is sliced too thick, and sometimes it is too thin. This lesson, however, is perfect porridge.
