Be2 It seems that black has already equalized comfortably to me, and the players seemed to agree. But black must take care that white's eventual expansion with f4 does not cause some chaos in his ranks. However, since this proves to be surprisingly hard to solve, white's position may be better than it looks. 14... Bc5 (14... f5!? 15. Nd5!? Qd6 16. Ne7 Qe7 17. ef5 Bf5 18. Qb3 Kh8 19.

The strength of Petursson's sidestep to a4 becomes more evident as the game progresses, when one of black's greatest regrets is that he has had to use his f-rook on d8.) 16... Rd8 17. Qc2 Bd4 18.

He has played terribly logically and sensibly, developing in the most active way. He has maintained a small initiative but white's only trump, the possibility of e5-e6, seems destined to swing the balance gently in his favor. Inferior were: (24. Nb5?! Be3) (24. Bf3?! Bf3 25.
