Thus, Chessmaster rules all! Of course, I put TI-CHESS on its easiest difficulty level, and
Chessmaster 86 on its hardest, and TI-CHESS beat it 34-13, but that just proves how much
I suck at chess! Unfortuneately, you can't get an easy game out of TI-CHESS, you can in Chessmaster!
Also notes the fact that TI-CHESS's puzzles are more than 10000 bytes, while mine are in a 1970 byte
program, and they are the same 75 puzzles! (Thanx for the puzzles, TICT)
