Homeostatic Chess Player Games

These are some sample games I played against my Homeostatic Chess Player.

An Interesting Computer Chess Game

Over Thursday and Friday morning (January 16^th) I played an interesting game with my chess applet, with a minimum look-ahead depth of six. At that level (maintained by incrementing the look-ahead with control-I as necessary) the computer can take an hour or more to move, depending on the current branching factor.

Rick Wagner versus Homeostatic Chess Player on an Intel Core i7, minimum search depth = 6
Double fianchetto opening

	White	Black
1.	Nf3	e6
2.	g3	Nc6
3.	Bg2	Nh6    This knight move is not usual for humans but characteristic for this computer chess player (fig. 1).

4.	O-O	Be7
5.	b3	O-O
6.	Bb2	f5     The point of the earlier knight move: keeping his lines open (fig. 2).

7.	c4	Rb8
8.	Nc3	b6
9.	d4	Bb7    Black fianchettos his queen's bishop (fig. 3).

10.	Re1	Na5    White prepares a pawn advance.
11.	e4	fxe4
12.	Nxe4	d5     Black blocks in white's queen bishop behind the white queen pawn (fig. 4).

13.	cxd5	exd5
14.	Nc3	Kh8
15.	Ne5	c6
16.	Bh3	Bc8    Contesting the diagonal (fig. 5).

Fig. 5: Position after 16. ... Bc8.

17.	Qh5!	Bd6
18.	Re3	b5
19.	Ra1e1	b4     White occupies the open file.
20.	Na4	Bxh3
21.	Qxh3	Qc8    Black is now desperate to neutralize white's attack (fig. 6).

Fig. 6: Position after 21. ... Qc8.

22.	Qh5!	Rb5?   ... Rf5 might have been better.
23.	Nc5	Nb7    White offers the sacrifice of a pawn to get an open diagonal for the queen's bishop but black declines.
24.	Ne5d7	Rg8    White's attack is now irresistable (fig. 7).

Fig. 7: Position after 24. ... Rg8.

25.	Re8	Qc7
26.	Rxg8+	Nxg8
27.	Re8	Nd8
28.	Rxg8+   Black resigns. Mate is coming.

Fig. 8: Position after 28. Rxg8+. It's mate in two so black resigns.

Computer is White

The computer is black by default. Do control-R to rotate the board and put white at the top, and then control-C to make the computer compute the first move. The chess player applet automatically records the moves. My annotations were added later.

For stronger play, the computer can be held to a particular search depth with control-I to increment the look-ahead depth. Turn on the Java console to see search depth. Control-V turns on verbose mode for more information in the console.

To use the chess player applet to view these games, put it into human-human mode with control-H. Then move the pieces for both sides in accordance with the listings below.

5.	Nf3	Nc6
6.	d4	Qf5
7.	a3	Nf6	White makes a phrophylactic move of the rook pawn.

9.	O-O	Nxc3
10.	bxc3	Qd5	Black neglects development.
11.	c4	Qd6
12.	Bb2	e6
13.	d5	exd5	Undoubling white's pawns.
14.	cxd5	Ne7	Cramped, but other knight moves are no better.
15.	c4	O-O-O
16.	Be5	Qa6
17.	a4	Ng6	White prevents Ba4.

19.	Rb1	Bf5	White finally takes control of an open file.
20.	Qb3	Bxb1	The exchange sacrifice retains white's control of 
21.	Rxb1	b6	  the file and eliminates black's active bishop.

24.	Qa6+	Kb8
25.	axb6	Bxf2+	Black declines the sacrifice of the bishop, but takes the pawn.
