July 2018 Chess Games

The games shown here were played against my chess applet, the Homeostatic Chess Player, a computer program I wrote in the first year of this century.

Scotch Four Knights Game

Computer played white, minimal look ahead is six tempi. 1-3 July.

	White	Black
1.	e4	e5
2.	Nf3	Nc6
3.	Nc3	Nf6	The classic four knights game.
4.	d4	exd4    Scotch game variant.
5.	Nxd4	g6      Black leaves the book.

Position after move 5.

6.	a3	Bg7
7.	Bg5	h6
8.	Nxc6	b7xc6
9.	Bh4	O-O
10.	f3	Re8

11.	Be2	a5
12.	Na4	d5
13.	O-O	Qe7
14.	Nc3	Bb7
15.	exd5	cxd5

Position after move 15.

16.	Bf2	c5?	White gets the initiative.
17.	Bb5	Re8d8
18.	Re1	Qc7
19.	Na4	d4?     White will win the exchange (bishop for rook).
20.	Bg3	Rd6	Black's only way to save his queen is to give up the exchange!

Position after move 20.

21.	c3	Ba6?    Not the best as the bishop will return to b7.

Scotch Four Knights Game

Computer played white, minimal look ahead is six tempi. 4-6 July.

	White	Black
1.	e4	e5
2.	Nf3	Nc6
3.	Nc3	Nf6
4.	d4	exd4
5.	Nxd4	Be7

Position after move 5.

6.	Nf5	O-O	To be theoretically consistent black has to allow white to take the bishop with the knight. Theory
7.	Nxe7+	Qxe7	holds that white is wasting time. His knight has four tempi invested while the bishop has one, with
8.	f3	d6	the recapture developing the queen.
9.	Be2	h6
10.	Rb1	Re8

Position after move 10.

11.	Bf4	a6
12.	h4	Bd7
13.	h5	Ne5
14.	Kf2	c6
15.	Qd2	Be6

Position after move 15.

16.	Qd4	c5
17.	Qd2	Ra8d8
18.	Rh2	Nc6
19.	b3	d5!
20.	e5	Nd7

Position after move 20.

21.	Nxd5	Bxd5
22.	Bxa6?	bxa6	A case of pushing the really bad news, I suppose, over the time horizon of six temp.
23.	Bxh6?	gxh6	Ditto.
24.	Qxd5	Nd7xe5
25.	Qe4	Qf6	Black is two knights up for two pawns. The rest is just mopping up.

Position after move 25.

26.	Kf1	Rd4
27.	Qe2	a5
28.	Rh1	Re8d8
29.	Qb5	Rd1+
