If you play the Dutch you have to be alert to the Anti-Dutch systems and one of the most popular is the tricky 1 d4 f5 2 Bg5. I've used this move against the Dutch a few times and it is true that black has to be extremely careful when facing it because many players have fallen victim to a miniature! When meeting 2.Bg5 it's recommended that French and Stonewall players should play 1…e6, Leningrad players should use 2…g6. While the risky line 2…h6 3.Bh4 g5 4.e4 is playable, I think black should avoid it because it's the move that often gets black into trouble.
In a couple of recent correspondence games where I played the Dutch, I am toying with playing a Benko Gambit-like move, an early ...b5. Before actually playing it, I subjected the diagrammed position to a deep position and infinite analysis using Komodo 10. After letting Komodo work on the position for a few hours, here's the resulting analysis. Clearly, white stands better, but I am willing to try it anyway...except against one opponent in particular; he is an ICCF SIM! It might be worth a try in blitz, or maybe even in a tournament game if you are feeling adventurous.
