I think that below 1600, the exchange french is more likely to result in drawish positions than for people higher rated than this. Beginners don't try different approaches or alternatives. The play straightforward: they see an open files and put their rooks there, so major pieces are going to be retired from the board in the early middlegame, and the symmetrical structure dictates the rest of the game.
Before I started to study carefully the exchange as Black, a lot of my games in that line ended in BvK endgames (or BvB or NvN) with that symmetrical pawns. Theoretically drawish? Of course. A draw? Well, plenty of errors by both sides to make a draw less often than two strong people would got from that positions statistically, for sure !
Lately, lots of people (even below 1600) are playing againt french that 3.c4 lines, with an isolani complex battle arising. And las time I get 3.Nc3 in a "long" OTB game... well I don't remember when it was
Lately I am facing (I'm 1800 FIDE playing vs a 1700-2100 FIDE opposition; very hard for me I have to admit):
- 40% 3.Nd2
- 30% exchange
- 20% Advance Variation, usually 6.a3 vs my 5...Bd7
- 10% rest of options (very few Nc3, and very few KIA surprisingly)
Salut,
