This is a very recent trend with White scoring well, although I doubt that 8 f4 poses a serious threat. 8…a6 There follows an encouraging recent example where White gets to execute his plan: 8…g4 9 d5 a5 10 b3 c5 11 d×c6 b×c6 12 h3 d7 13 d2 c5 14 ad1 c6 15 h6!

Very interesting. Black forces White to sacrifice the exchange and with his king apparently wide open gains considerable counterplay. But with the black queen able to return to g7 at a moment’s notice, perhaps White’s pressure is only good for equality. 22 ×d5
