The South was victorious in the traditional Battle of Alberta, held at Red Deer. Despite rating equality between the teams, the South amassed a huge lead over the North in the first round, then coasted to a 14.5 to 8.5 victory.

Amassing 2-0 scores for the winners were Chris Demers, Andrew Boik and Ian Lee. Mr. Lee had White against Anastasia Kazakevich.

1.e2-e4 c7-c5 2.Ng1-f3 e7-e6 3.d2-d4 c5xd4 4.Nf3xd4 a7-a6 5.Nb1-c3

There are many subtleties of move order. Here 5.Bf1-d3 is more popular because it keeps c2-c4 available.

5. ... Nb8-c6

This is the fourth most popular, and the ninth most successful move, with a 43 per cent yield.

6.Nd4xc6 b7xc6 7.Bf1-d3

White has been doing well in top grandmaster play with the unnatural 7.e4-e5 Qd8-c7 8.f2-f4.

7. ... Qd8-c7 8.O-O d7-d5 9.Qd1-e2 d5-d4

The move gains time, but cedes c4 for good. Black usually parries the threat against the d5-pawn by protecting it again with Ng8-f6.

10.Nc3-a4 e6-e5 11.f2-f4 Bf8-d6 12.f4-f5 Ng8-f6 13.b2-b3 Bc8-b7 14.Na4-b2 Bd6-b4

An aggressive and committal move. Among the alternatives are 14. ... Bd6-a3, hoping to trade off White's versatile Bishop, or just castling.

15.Nb2-c4 Bb4-c3 16.Ra1-b1 O-O

Having isolated the Bishop in enemy territory, Black needs to be more careful about King placement. If 16. ... O-O-O then b3-b4 and a2-a4. That and the game continuation suggest that Black needs to cripple White's pawn rollers before committing the King. For example, 16. ... a6-a5 17.a2-a4 h7-h5.

17.g2-g4! Nf6-d7 18.g4-g5 f7-f6

The additional weakness along the c4-g8 diagonal is more than Black's position can bear. A better defence was 18. ... Rf8-e8 19.Qe2-h5 Nd7-f8, intending not to move any kingside pawns when f5-f6 arrives.

19.g5-g6 h7-h6 20.Bc1-a3

Also good was Qe2-h5. After the moves in the game, the Bishop at c3 cannot return to the hinterland.

20. ... c6-c5 21.Qe2-h5 a6-a5 22.Ba3-c1 Bb7-a6 23.Rf1-f3 Nd7-b8 24.Rf3-h3 Ra8-a7

Now comes a stock sacrifice, but White finds an original continuation.

25.Bc1xh6! g7xh6 26.g6-g7!

Also strong is 26.Qh5xh6 Qc7-g7 27.Qh6-c1, intending Rh3-h7.

26. ... Rf8-f7 27.Qh5xh6 Rf7xg7+ 28.Kg1-f2 Kg8-f7 Diagram: Black appears to have escaped, but White has one more touch of magic:

29.Qh6xg7+! Kf7xg7 30.Rb1-g1+ Kg7-f7 31.Rh3-h7+ Kf7-f8 32.Rh7-h8+ Kf8-f7 33.Rh8-g8!

The key move.

33. ... Bc3-e1+ 34.Kf2xe1 Ba6xc4 35.Rg1-g7 mate.

Micah Hughey scored 2-0 for the North.
