As a side note, in 10 days GM Oscar Panno, the Argentine legend, will celebrate the 70th anniversary of his World Junior title. Congratulations $1 8. d4d5  8... c6b8 The modern move. 9. e2e4  9... a7a5  10. a1b1 This move was also played in the first game of the match. Iturrizaga knows this line well: he faced the Brazilian GM Alexandr Fier this year but chose instead the more natural 10.Ne1. 10... b8a6  11. f1e1  11... a6c5  12. b2b3  12... c8d7  13. h2h3 An useful waiting move. 13... h7h6 If he plays h3, I can play h6. This is a good motto, especially in games with fast time controls. It might not be the most accurate, but certainly, it will not be very bad either. 14. a2a3  14... g8h7 This move doesn't help Black's position 15. d1c2  15... b7b6 [%c_effect b6;square;b6;type;Mistake;persistent;true] 16. b3b4  16... a5b4  17. a3b4  17... c5a4  18. c3b5 [%c_effect b5;square;b5;type;GreatFind;persistent;true] The knight is stuck on a4, and Black is already losing. 18... c7c6 A desperate attempt to save the poor knight. 19. b5d6  19... d8c7  20. d5c6
