Hello everyone.  I am a fairly aggressive otb player with a rating hovering around 1800.  I was wondering if I want to play aggressive is the classical or the leningrad dutch a better choice?

Thanks

If you play against me OTB, you won't get a chance to play the Classical Dutch. I play 1. d4 f5 2. Bg5.

Well ok but I'm more talking about someone that plays into "mainline" not some offbeat sideline

I am new to the dutch defense aswell, and I am planning to focus on the leningrad. I believe the leningrad is the most aggressive but also the most theoretical by far. The stonewall might be a good choice too, it is aggressive and not as theoretical.

Playing the Leningrad is alot like playing a wierd KID and is probaly less agressive but also less liable to horribly fail than classical dutch. Realy the only thing Leningrad dutch and Classical dutch have in common is 1.f5

Ouch 19.Rd8!!

Very well, but you should be aware that people won't always play the "mainline", especially against offbeat openings like the Dutch.

You've never played at my club :p

7...Nc6 is considered a weaker line nowadays.  The mainline Leningrad is 7...Qe8; 7...c6 is also playable.

I was a longtime Dutch skeptic, because when I was a d4 player, I was on the White side of numerous crushing victories against the Stonewall & Classical.  I've been playing the Leningrad myself a lot lately, though, and I've been pleased with the results.

I did like the finish in your game.  Allow me to offer a contrasting view from the black side, though:
