Subject: Is Mega Database in danger of becoming FatBase?

The number of games each year in ChessBase’s “flagship database” (their term)
keeps whizzing rapidly upwards:

Mega Database 1999   1.1 million games
Mega Database 2000   1.4 million games
Mega Database 2001   1.7 million games
Mega Database 2002   2.0 million games
Mega Database 2003   2.3 million games
Mega Database 2004   2.6 million games
Mega Database 2005   2.9 million games

It’s just about 300,000 games per year.  Yet if you were to collect all of the
new games compiled by Mark Crowler in TWIC for one year you would end up with
about 75,000 to 80,000 new games for that calendar year.  Where are the extra
games coming from?

To me it doesn’t look like they’re coming from any good sources.

Case in point:  Take the classic beginner’s opening 1. e4 e5 2. Qh5.  Now I
would expect that in a quality or “flagship database”, there shouldn’t be any
more than 5 or 6 games with that silly opening by White.

I did a search to find out how many games in Mega Database 2005 started out with
1. e4 e5 2. Qh5 and was shocked to find out there are 258 games!!  Even worse,
White actually wins 94 of those games!

Want more?  Well after 1. e4 e5 2. Qh5 there are a flabbergasting 80 games, yes
count ‘em 80, where Black replies 2... Nf6?? and loses a pawn instantly to 3.
Qxe5+.

Is Mega Database in danger of becoming FatBase?  At least in the FatBase product
they are honest enough to tell you that the games include a lot of garbage.
Just because all the headers and names are consistent doesn’t mean quality if
you have hundreds of games that start out with 1. e4 e5 2. Qh5.

Even worse, in their search for more games regardless of how awful, they are
still leaving out some quality games.  In a few opening treatise’s there is
occasionally a reference to a game that I cannot find in Mega Database.
