Many of us are still shielding and over-the-board tournaments are only just starting up again. So once again the clinic is devoted largely to internet games, with all their 'variability'. I think that one of the main issues with such games is their low value, if you lose you can easily find another opponent and may have better luck. Inevitably this means that playing standards will be highly variable.
This month's clinic featured a cross section of such games together with some interesting points. It was also gratifying to see a win for White using the White 1.d2-d4 Repertoire Course, a game by M. L. reaching the following position after the moves 1. d4 Nf6 2. Nf3 g6 3. c4 Bg7 4. Nc3 d5 5. cxd5 Nxd5 6. e4 Nxc3 7. bxc3 O-O 8. Be2 c5 9. O-O Nc6 10. Be3 Bg4:
Despite the fact that all his moves look 'natural', Black had in fact played inaccurately with the nonchalent 7...0-0 instead of 7...c5 8.Be3 Qa5!. This now gave White the opportunity to play 11. d5 and after 11...Bxf3 12. Bxf3 Ne5 13. Rc1 b6?! 14. Be2 e6 15. c4 exd5 16. cxd5 Re8?! 17. f4 Nd7 18. e5, White had obtained a crushing position and soon went on to win.
This is one of the issues with the Gruenfeld, it needs Black to play very accurately. And this in turn is why I tend to recommend the Queen's Gambit Declined for Black, it's much more forgiving if you play it inaccurately.
