Introducing the Sveshni-Dutch defense (N)

1) Start by playing the Dutch defense
2) Create a hole on d5 but have some control over e5 and d4
3) Confuse the opponent
4) ???
5) Profit ! :-)

Hey achja!
Cool game but I may have to disagree....
You're playing blitz,
in rapid,something else could occur
And it's not a guarantee that profit could occur
If that's true, why would anyone play the KID or benoni?
They'd switch to sveshni-dutch
Basically,my point being-
You don't have a guarantee of "profit" by playing an opening.
If your opponent doesn't make a mistake/bluder,
we could have a disadvantage.

Thanks for your comment !
First of all a disclaimer, my post here was 67% for fun, and 21% serious and some unknown % various & unknown
Having said that, playing unusual side-lines in serious OTB chess games can perhaps put some pressure on the opponent.
There is a book series called S.O.S. which are booklets only about off-beat opening lines, "collected" by IM Jeroen Bosch and written by various chess players, including GM Dimitri Reinderman.
Those books show games with off-beat opening, sometimes unsound, played in otb chess, and sometimes by GMs.
To give another example, Englund gambit is unsound, but was played here in otb chess against a GM :
lichess dot org/study/vziEX4WV firs chapter.
Aman Hambleton, now GM, played that.
And what about GM Nakamura playing an early Qh5 on move 2 in otb against a GM (and losing) ?
Or Magnus playing that weird looking early Nh5 line in otb chess ?
Chess between humans is not ice cold calculation like chess between chess engines.
Psychology is also a part of chess, conscious or sometimes we are even unaware that is was a factor (Think about Magnus Carlsen who saw that Alireza Firouzja got nervous in that last game, which was draw, but Magnus decided to play on).

Having said all that, I am willing to play the Sveshni-Dutch in slower time control games or even OTB (when that will be a thing again in the future...).
But first ... more chess research to do in the lab, see you later alligator ! ;)

HTH ;)

I am struggling to identify a critical line, but at move 12, the evaluation is above +2, and a few moves later it touches +4.

I know engines are not perfect, but if it says +4 in such a position I am sure black is losing.

Let me know if you find the clear punishment.

It often pays to get the opponent out of his opening preparation and force him to play his own moves.
Lasker already deliberately played bad openings and called it "odds style" ('Vorgabestil')
Carlsen also regularly plays weird stuff against lesser grandmasters. As if he says: "let us play chess, not opening theory"

@Testrider
Thanks for mentioning that ! I had not looked at the analysis of this game yet.
After white 11th move SF claims the position is equal.
Then after black's 11th move suddenly white would be winning.
Maybe good to note, if you follow the Stockfish recommendation 13.Nf4 the evaluation drops from +3.3 to under +2.0 for a while and it seems a bit indecisive for a while about which move is the best.
That is a quite a difference, making it from white is winning to white is clearly better.
The big question for me is : Will humans manage over the board to find the best moves for white ?

Admittedly finding the strongest line with 17. f3 is hard

And I believe I found the reason why that line is so strong. After kicking back the N with h4, white threatens Ne6, and suppose he can capture on g7, then afterwards he has a pin with f4.

---

So, objectively black is in trouble, but suppose humans don't find this move often, in practice I do expect them to easily find other moves to avoid the pin on f3, for instance Kg2 or Qe2.

Now the game is fairly stable, but the defining factor is the weakness of the e6 pawn. White has a clear point to attack, and black needs to fully focus on defending it, or solving the situation somehow.

Think about it, what is the easiest way to solve the problem of e6... 14. ... exd5!
As such I would not recommend the line with Nxd5 instead.
