iOS Tournament - HIARCS vs Stockfisch

[JuLieN]

As was discussed in this topic, I'm starting a small tournament for iOS chess programs. I selected 9 programs:

- ChessGenius
- Christophe Théron's Chess
- Deep Green Chess
- Hiarcs Chess HD
- Fritz
- Shredder HD
- Stockfish
- tChess Pro
- Viktor2

And maybe more if someone suggest some.

All the engines will be opposed to all other engines during 4-games long matches running at 30mn/side for the game, on a New iPad (iPad 3?).

The first match opposes HIARCS to Stockfish.

Here's the first game:

[Round "1"]
[White "Hiarcs iOS"]

[Result "1/2-1/2"]
[EventDate "2013.01.01"]

Nothing too fancy. Both program played their first out-of-the-book move at the 18th move.

I stopped the game at the 49th move, as both engines were agreeing on a draw score since a few moves.

The second game is a draw as well. But more interesting. HIARCS was out of the book at move 11, and Stockfish at move 13.

HIARCS decided to exchange three of its pawn for Stockfish's knight but eventually had to exchange it back against two pawns, as Stockfish was menacing to queen a pawn. HIARCS' ending technique prevented Stockfish to get a win out of this material advantage.

The third game is a gorgeous victory by Stockfish, with black pieces and the very proactive style that is its marque de fabrique (both engines were out of book after white's 6th move):

(Note: HIARCS crashed after Stockfish's 70th move!)

Stockfish played several magnificent moves, like 12. ..., e4; ... 21. ..., a4; ... 24. ..., exd3; ... 28. ..., Nb3; 38 ..., Nd3!!; etc...
