One of the most effective anti-Sicilian players is the Hungarian Dely; here is yct another of his crushing wins, this time in a train- ing tournament for the Tel Aviv Olympics. The game is of some theoretical interest, as it shows a successful sacrifice by White of his K 11, one of the standard targets for Black attack in this opening. The lesson is the u. ual one we all have to Learn over and over again—it is dangerous to win material at the expense of develop- ment in open positions; the trouble is that one always hopes (when one yields to temptation) that this is one of the cases where the pitcher won't get broken.
