14...Ba8? 15.e4 It’s funny, but Black’s position is solid — but strategically it’s completely lost!

Black exchanges the maximum of pieces in order to find some space for the remaining ones.

With the idea of playing e2-e4.

18...Bc3 19.Bd2 Qe7 20.Bxd5 exd5 21.Bxc3 Qxc5 22.Rd3 Rb7 23.Rc1 bxc3 24.Rxc3 and White gets a very good endgame a pawn up.

The French player gives up his strong bishop for a good reason; he wants to paralyze the black queen-side.
