MARK RUBERY CHESS
The O’Sullivan Memorial Tournament used to be held every May is an annual tribute to the twins Michael and Kevin O’Sullivan who were prematurely taken from us-Kevin in 1988 and Michael in 1996. This speed event began in 1988 and continued to 2005 and featured many of the best players of that era. Both players were immensely talented and were from a young age particularly accomplished in the endgame; one example saw Kevin confidently outplay the visiting IM David Levy in that phase of the game during the Uitkyk International 1978. Both twins specialised in a few opening systems which they passed on to their pupils thus the French Defence Goring Gambit and Max Lange Attack became quite fashionable on the SA circuit during the 1980s.
Here are a couple of examples of the twin’s prowess over the board.

1.c4 e5 2.Nc3 Nc6 3.e3 f5 4.d4 e4 5.f3 Nf6 6.d5 Ne5 7.fxe4 Nxe4 8.Qd4 Qf6! (Offering a pawn this White is unwise to accept) 9.Nxe4 fxe4 10.Qxe4?! Bb4+ 11.Bd2 Bxd2+ 12.Kxd2 0–0 13.Rd1 d6 14.Be2 Bf5 15.Qd4 Rae8 16.Nh3? (White can continue to resist after 16 Nf3. Now the game ends suddenly) … Bxh3 17.gxh3 Qf2! 0–1 (As the threat of … Nf3+ cannot be met)

Where a mediocre chess player sees ten moves to continue his game, a master may see only two or three. He discards the others as not of sufficient merit. The further the master progresses in skill and foresight the more he is restricted in his choice of moves. It is very similar in other disciplines. If a mediocre pianist plays a piece before a musical audience he will imagine that he is able to execute his task in a variety of styles. But for Rosenthal or Paderewski only one way of rendering the piece will exist. The higher the class of the artist, the less is his liberty. – Emanuel Lasker
