HIARCS iPhone v Chessmaster GM

[Carl Bicknell]

For old times sake I decided to test The Chessmaster GM edition running at 3.6GHz (2 cores used) vs the new upgrade of HIARCS iPhone 13.31. My iPhone is the iPhone 4, clock speed 800 MHz. The difference in speed between the two is therefore considerable.

I played a 10 game match at G30. The final score was 6-4 in favour of HIARCS iPhone, which is an achievement. HIARCS was using my subscription book and this gave it a BIG advantage over CM's old book, but even so it was impressive to see the 'little guy' win.

Here's a nice win by HIARCS:

EDIT: Before the upgrade I ran exactly the same match with version 12.4 of HIARCS iPhone using the stock book. The match ended 7-3 in the Chessmaster's favour.
