Not every game.
I am entering mating patterns, piece positions and formations that are
the seed for combinations, also looking for manourvers like Bxh7+,
pawn promotion tricks, etc etc. then do a databse search.
I have split the DB (1,119,089 games) into 1-10, 10-20, 20 -30 etc etc.
to save search time.
Sometimes I get hundreds and I click on each one, lucklily the DB shows
the game from the positon I seek and I quickly decide if it's interesting
This is where the good chess player bit comes in handy.
I have unearthed some smashing stuff.
Of course I'm not looking forward to the ending stuff. I peeked and there
are thousands of K+ Q K mates and quite a few stalemate.
Also hundreds of K + R v K mates. Only found one stalemate here to date.
It's quite hard to actually stalemate with K + R if you do not mean it.
The rule of thumb for the 1400 players is to promote ot a Rook as it
lessens your chance of stalemate.
I have also isolated all games that ended 1-0 or 0-1 on exactley 25 moves,
28,833 those I am going to blunder check at 1 sec move range 200.
then do a search for !! and ?? this should find combinations played and missed.
*I've done over 500 already and that was just to see if I got the criteria right
I think I have.).
I chose 25 because it's the limit of the miniature and it also passed the bounds
of two clowns (or one clown with a double account) messing about. (see below).
Here is the quickest double pawn promotion Game 4076653
This is obvioulsy a composed game possibly by one user with a double account.
If you look at the 30 odd games between these two you see all kinds of
junk - fools mates etc.
I sensed composition the moment I saw the game - this one was easy,
others are a wee bit harder to spot. (again the good player bit....)
Both are now banned one got to over 2100 before the ban, the other over 1700.
