The Russian GMs Vladimir Potkin and Ian Nepomniachtchi not just drew in the second round of the Capablanca Memorial that takes place in Havana, but broke new ground in, at the same time, two openings.

1.c4 c5 2.Nf3 Nc6 3.Nc3 g6 4.e3 Nf6 5.d4 cxd4 6.exd4 d5
The game went from English opening to Panov-Botvinnik attack of the Caro-Kann defence. 

7.cxd5 Nxd5 8.Qb3 e6 9.Bb5 Bg7 10.Bg5 Qb6 11.Qa3 f6 12.Nxd5 exd5 13.Bxc6+ bxc6 14.O-O Kf7
Perhaps, first this kind of position took place in Nepomniachtchi - Leko encounter last month in Russian League. There was 15.Bf4 Re8 16.Bd6 Qa6!, and Black solved all its problems.

This opportunity was briefly noted in the report of the last session of Austrian Bundesliga on our site (15...Qb7 was played in Ragger - Volokitin, Austrian Bundesliga 2012, where Black lost unable to solve its problems). 
16.Qe3 fxg5
Looks like a principle variation, which can be confidently recommended for Black.
