- New in MacChess 3.0 Rotterdam 12/8/96
-
- First, a special "thank you" to Richard A. Fowell.
- He helped test MacChess 3.0 and proofread my English.
-
- Special thanks also to Morten Larsen for testing MacChess 3.0 and to
- everyone that gave me support and advice by sending me postcards and email.
-
- ====== NEW FEATURES ======
-
- 1. PowerPC native - MUCH faster (and much stronger) on Power Macintoshes.
- 2. Special "Easy" levels for learners to play against.
- 3. "Next Best Move" option for getting the second best move.
- 4. A "Log" option to record MacChess's analysis during a game.
- 5. An Analysis mode for running a set of EPD test positions in "batch" mode.
- 6. Updates the nodes and nod/sec information more frequently.
-
- ====== FIXED PROBLEMS ======
-
- 1. The "Sliding Pieces" and "Notation" preferences are now saved properly.
-
- ====== PPC NATIVE ======
-
- MacChess is now PowerPC native, with the chess engine hand-coded in PPC
- assembly language. MacChess now runs about 13 times faster on a "stock"
- 6100/66, and twice as fast as it ran on a 6100/66 with Speed Doubler.
- Also, there's no need to buy Speed Doubler to improve MacChess's performance
- on Power Macintoshes. This increased speed makes MacChess much stronger.
-
- However, MacChess 3.0 runs only on Power Macintosh computers and won't
- run on 68K systems. Because MacChess is hand-coded in assembly language,
- I can't maintain two parallel versions. If you don't have a Power Macintosh,
- use the last 68K version of MacChess (MacChess 2.5.1).
-
- ====== EASY LEVELS ======
-
- There are now 6 "easy" levels, for people who find MacChess is too tough
- an opponent. Those levels use no extensions at all,
- and MacChess does not look very far ahead.
-
- Easy Random: Random moves for fun.
- Easy Easy: MacChess thinks a Queen is worth the same as a Knight or Bishop.
- Easy 1: 2 ply deep (one move by each side)
- Easy 2: 3 ply deep.
- Easy 3: 4 ply deep.
- Easy 4: 5 ply deep.
-
- ====== NEXT BEST MOVE ======
-
- This lets you see what MacChess thinks is the "second best" move.
- MacChess repeats its analysis, excluding the move it had chosen as best.
- It only excludes one move, so if this command is used repeatedly,
- it alternates between the "best" and "second best" moves.
-
- ====== LOG FILE ======
-
- This option saves MacChess's search output during a game to a log file.
- This is a convenient way of seeing what MacChess thought you should
- play when reviewing a game afterwards.
-
- ====== ANALYZE EPD POSITIONS ======
-
- MacChess will now analyze every position in a .epd file with one or more
- EPD positions. This is a much easier way to have MacChess analyze
- a position (or series of positions) than before, since no index file is
- required, and all the problems can be kept in a single file.
-
- ====== NODE AND NOD/SEC UPDATE======
-
- The "nodes" and the "nod/sec" outputs update more frequently
- (after approximately 500 K nodes - every 10 seconds or less).
- A "node" is a possible future position.
-
- ====== FEATURES IN WORK ======
-
- Analyzing an imported game for white or black.
- Analyzing and showing the main line in the "player vs player" setting.
- Improved playing strength.
