kind of too late for that i THINK . if you just push ...g6, you'll have a lenningrad plus ...e6. play ...d5, and you have a stonewall, but as an attacker myself, I wouldn't recommend it.
there's a new system called "the killer dutch" which plays ...d6 instead of stonewall's ...d5.
I know nothing about it other than it SOUNDS aggressive, and the original dutch that you have there is considered aggressive.
looking at the stats for the straight up lenningrad... they're better than stalefish's STANK suggestion! you can't trust SF for your theory! trust me! often the lines it likes best are the worst performing otb.
using stats... you base your play on real world opponents and following the lines where they mess up the most. you're playing humans, not engines. it trust stats more than SF any day, but use it to verify. some winning lines are -5 points... a bit too risky if an opening is new to me. with stats, you get to cheat of EVERYONE's homework! when you follow the strongest lines, eventually you find traps and mates in 8. engines think weird and expect opponents to play like them and not humans.
these stats are for games rated 1600-2000 where GM lines aren't always the best otb
stalefish's ...e6
lenningrad dutch
and other moves have even better stats:
3...h6 has THE BEST stats with a big main line, but not so hot 2nd line
62% is a JUICY main line!
3...b6 is probably BEST. it's a couple % lower in the main line, but is winning in the sidelines too, and there's only 2 really popular lines (I avoid strong lines where I need to know theory for a dozen replies where a line that's forcing for a couple moves with no sidelines seems a lot more reliable and easy to retain)
id's never play this OR the lenningrad because i hate fianchettos myself, but I can see how the QS fianchetto is strong as you're hybridizing with QIA and dual fianchettos is a universal system
3...d5 is playable, but that's pretty much insisting on stonewalling and unless you're good at positional play and don't mind closed positions and flank attacks, but as a pure tactician myself, i quit playing over it constraining me like a straightjacket i can't breathe in.
and finally, 3...d6 will turn into a killer dutch after ...e6.
if you REALLY want to get tactical, watch THIS video and try the englund gambit hartlaub/charlick variation!
it's not OBJECTIVELY sound at -2 points, but I've never had this much fun playing black and am DESTROYING opponents with mostly simple plans and haven't even really studied it much beyond the video and looking into the d5 declined push in which I'm playing dutch/king's gambit like ...f5 and ...Bc5 which is way more fun than anything in the stonewall at least. i'm biased against ANY dutch lines because i hate the stonewall SOOOO MUCH, but it IS playable against pretty much everything except 1.e4 and 1.g4. it does well against the much feared london system, but with 2...e5!?, london pre-movers hand you their bishop free. caught a player like that once already.
you gotta like risk for it, and be prepared to deal with an OCCASIONAL player who knows what they're doing and who plays the strongest lines which no one has YET.
what i love about it is that after
there's a 33 page pdf by new in chess here on the system if you want to check that out
I have researched and found the LG to be a good fighting weapon. However through looking at the engin analysis black plays e6 against Bg5. Here is a diagram of what I am telling...
However g6 is what I am really looking to play. Is there a line to transpose into a Leningrad Dutch?
