- History of MacChess - Wim van Beusekom
-
- ======================================================================
-
- TOBBER Atari Rotterdam 1989
-
- I entered my TOBBER (Atari) chess program in the Dutch Computer Chess
- Championships in 1989 and 1990. These were organized by the CSVN
- (Computer Chess Association Netherlands).
-
- In 1989 there were 14 programs and I was 11th with 2.5 points out of 7.
- in 1990 there were 16 programs and I was 10th with 3 points out of 7.
-
- After this I stopped programming for a while.
-
- ======================================================================
-
- MacChess 1.0 Rotterdam December 1994
-
- In April 1993 I began converting TOBBER to an Apple Macintosh.
- MacChess 1.0 is nearly identical to TOBBER (Atari). On a Classic II
- MacChess 1.0 is comparable to the Kasparov TEAM-MATE chess computer
- and on a Centris 610 to the Mephisto MMII.
-
- MacChess 1.0 was developed in THINK C,
- the interface has been written in C and
- its search routines were written in assembler.
-
- In October 1994 I visited the 14th Dutch Computer Chess Championship
- and was inspired to play again at the 15th Championship in 1995.
-
- ======================================================================
-
- MacChess 2.0 Rotterdam December 1995
-
- In November 1995 I entered the 15th Open Dutch Computer Chess Championship.
- There were 20 programs and I was 12th with 5.5 points out of 11 games.
- MacChess ran on a Macintosh Centris 610 (20 MHz).
- This was the best result to date.
-
- MacChess 2.0 was tactically improved by using null-moves and better
- move ordering techniques.
-
- Positional play and end games are still weak.
-
- ======================================================================
-
- MacChess 2.5 Rotterdam June 1996
-
- I slightly improved the chess engine, and made many enhancements in the
- user interface and import/export facilities. The only changes between
- MacChess 2.5 and 2.5.1 were some minor bug fixes.
-
- Major New features:
- - Sliding pieces
- - selectable board patterns & a new piece set
- - PGN/EPD import/export
- - separate mating module
- - batch position analysis.
- - greatly enhanced game review capabilities
-
- ======================================================================
-
- MacChess 3.0 Rotterdam December 1996
-
- I entered the 16th Open Dutch Computer Chess Championship this November.
- MacChess placed 7th out of 20 programs with 6 points in 11 games.
- MacChess ran on a 200 Mhz Power Macintosh with a 604e processor
- supplied by Apple (Thanks!).
-
- This was the best result to date. The games are in the folder DOCC 1996.
-
-
- MacChess 3.0 is stronger than MacChess 2.X because it thinks much
- faster - it is now PowerPC native. MacChess 3.0 runs 13 times faster
- on "stock" Power Macintoshes than MacChess 2.X, which should make it a
- full rating class stronger. (People who use Speed Doubler to speed up
- MacChess 2.X on their Power Macintoshes will "only" double their speed
- by switching to MacChess 3.0.) Though MacChess 3.0 is faster than
- MacChess 2.X, it isn't much "smarter" - positional play and end games
- are still weak. MacChess 3.0 REQUIRES a Power Macintosh - if you
- don't own a Power Macintosh, MacChess 2.5.1 is the version for you.
-
- ======================================================================
-
- MacChess 3.0.e Rotterdam October 1997
-
- The primary addition in MacChess 3.0.e is ExaChess compatibility
- (The "e" in 3.0.e" is for ExaChess). ExaChess lets you play MacChess
- against other ExaChess compatible Macintosh chess programs automatically.
- Currently available opponents are: Crafty, GNUChess and ZZZZZZ.
-
- To download ExaChess Lite (which includes ZZZZZZ), access:

-
