August 21st 1976, Steady!
THE WORLD under-18 championship which has just finished in France was won by the Israeli player N. Grinberg with 7½/9. Despite sharing the lead for a long time, I failed to capitalise on some good chances in the final rounds and was just edged out of the title spot, only managing to score seven points. Four players shared third place with 6/9 - I. Rogers (Australia), G. Kasparov (USSR), M. Petursson (Iceland) and A. Groszpetter (Hungary).
A noticeable difference from ordinary events was the fact that each player was accompanied by a second. A second is an experienced player whose main job is to help with analysis of any adjourned games. However, for such an important tournament jt was essential to prepare openings in advance and I was greatly assisted in this by my second, the English theoretician Leslie Blackstock whose advice on openings was invaluable.
Grinberg played steady chess throughout, taking few chances. Here, however, is a game definitely not typical of his style!

An unclear position was reached in Donoso - Najdorf, Argentina 1971 after (9...Qc7 10.Qd2 b5 11.O-O-O Bb7 ) 10.h4 Nxd4?! Allowing the white queen a dominating position 11.Qxd4 Ne5 12.Be2 O-O 13.O-O-O b5 14.Rdg1 Eyeing the Black monarch! 14...Qa5 15.Kb1 Bd7 16.f4 Nc6 (16...Nc4 is a more aggressive possibility ) 17.Qd2 b4 18.Nd1 Na7 19.Bc4 Bc6 20.Nf2 d5! Black observes the well known maxim that a counter in the centre is the best antidote to a flank attack 21.Bb3 dxe4? (21...Rfd8 (threatening d4) must be played. It has the additional advantage that Bf8 is playable as a defensive measure. Grinberg now conducts the attack in fine style. ) 22.h5 Bd5 23.g6! Nc6 24.Ng4 f5 25.h6!

A pretty position in the assault - Black's king side is still intact and the white pawns are on the sixth rank 25...hxg6 ( or 25...fxg4 26.Qh2 where all lines win ) 26.Qh2 fxg4 27.hxg7 Kxg7 28.Qh7+ Kf6 29.Rxg4 Rg8 30.Rh6 1-0
Ian Rogers, the Australian, played some imaginative combinations. He impressed me in the second round with a really nice double-rook sacrifice - the point being one was sacrificed on b6 and the other on hl!
