In the late Sixties, the most interesting national team in the world was that of Canada. On top board, they had Duncan Suttles, a highly imaginative grandmaster with a penchant for developing his knight on h3 or h6. Typically as White he would open 1.g3, then continue with Bg2, Nc3, d3 and Nh3. On one memorable occasion, he went on with Bd2, Qc1, Nd1, f3 and Ndf2, to give the knight on h3 some support.

Lower down the team, however, was Lawrence Day, a player who, on his day, could make Suttles look quite unadventurous. Looking at some games from this year's Canadian Championship in Ontario, I was delighted to see that Day is still producing weird and wonderful chess.

The following game from that event may set some sort of a record. Of Black`s 40 moves, 18 of them give check. White, while all this is going on, makes 16 moves with his king - and wins the game. In the opening, White's 7.Nc3?! is not as good as 7.Nxf6+ Qxf6 8.d4 Bg4 9.Qd2, but Black's piece sacrifice with 7...Nxe4 looks highly speculative.

With White's king stumbling around like a drunk in a minefield, the rest of the game was hilarious. Black finally blundered his queen away as his attack ran out of steam, and resigned before White could get over the shock and take it.

After that, we deserve something a little more sober, so here is a game by England's own most imaginative grandmaster, played in a tournament at Leeuwarden in the Netherlands last month. After a curiously unambitious opening - 4.Nd2 looks considerably less aggressive than either 4.exd5 or 4.e5 - Speelman moves on to the attack with the uncompromising 11.fxg3.

His investment in the open f-file paid off handsomely with 21.Bxg6! which ripped open Black's defences. After 22.Qd3 Black could not defend g6, so tried to prevent mate on the f7 square. An easy sacrifice on f6 was then all it took to finish him off. In the final position 26...Ke7 27.Qg7+ is fatal, while on 26...Qxf6 27.Qxf6+ Kg8, the simplest way to end it is 28.Qg5+ Kf8 (Kh7 allows Qg6 mate) 29.Ng6+.
