i dont know the theory here but if he plays 3.Bx6 creating double pawns he gives away his bishoppair in return which is good for you so its not that bad
Trompowsky Attack


Thanks alot.
if after 2...d5 white plays anything other than 3.Bxf6 then after 3...e6 black will reach normal position.
I know that black have bishop pair but such kind of doubled pawns doesn't fit my style!
after 2...Ne4 3.Bf4 d5 4.f3 Nf6 5.Qd3 white will play c3-e4 with a great center!
the line 2...Ne4 3.Bf4 c5 is so theoretical and playing it against and wxperienced player in this opening is dangerous.
No one is saying this isn't White's plan, people who suggest it's bad strategy are suggesting it's not the best plan. Usually Black has to do some work hard to unbalance the position similarly for winning chances. Personally, I love playing with doubled pawns and an open file even without the Bishop pair.
Very strong players have said similar. Roman Dzindzichashvili in his video on the Tromp says simply "Trompowsky is wrong way to play chess."

I don't understand why you want to play 1. ... Nf6 in the first place. To my inexperienced eye, it defends nothing, attacks nothing, and presents the problem you have already identified.
My favorite response to 1. d4 is e6 Many times Nf6 is the next move, but then the doubled pawn threat no longer exists.
It looks soft and it took me a long time to understand it, but lately it's been really good to me. I used to cringe at 1.d4 and now I get really happy.

The point of Nf6 is to develop the knight, nothing more. It prevents a total central takeover by White, but gives maximum flexibility for the central pawns
(Nf6 stops e4; you might like e6 if you play the French Defense; op might want to play KID or something else where e6 isn't played.)

- It develops a piece and prepares for kingside castling.
- It controls some central territory and like another poster mentioned restrains white from moving a pawn to e4. For example 1.d4,b6 2.e4! is much harder to play as black than 1.d4,Nf6 2.Nf3,e6 3.c4,b6
- It is flexible, you know you want a knight on f6 usually whereas you don't always know where to place your d-pawn. Play may develop in a way where ...d6 is better whereas in other situations ...d5 would be better. For example 1.d4,Nf6 2.c4,e6 3.Nc3,Bb4 4.f3,d5 white hasn't moved Nf3 so the central break works really well here when ...c5 is typically played in other lines such as 4.e3,c5. If Nf3 then ...d6 may become useful at some point as e5 is a square white would usually love to plant a knight.

Thanks for the insight. Still, the OP sees a fundamental flaw with Nf6 so I think they should seek something else. It helps to have an opening that you're very comfortable with, although I know that takes time.
Regarding the e4 fear:
1. d4 e6
2. e4 d6
Black is now free to develop either knight with proper pawn protection. There is room to develop the king's bishop to enable castling quickly. Also there is a center clearing move possible with c5 which helps develop the queen side knight and open black's initially cramped position. This opening looks passive but it's not. It's a lot of fun IMO.
And don't forget there's a difference between occupying the center and controlling it.

Center pawns are static advantages. Just develop your peices fast and form a GOOD attack and it will level out. Also, center pawns are weak in the opening, giving more options for counterplay.
Ok after 1. d4 e6 2. e4 d6 White scores more than 70% in the database I just checked, maybe it's playable but anyway this is off topic. Nf6 is mainline and if White has a way to expose some fundamental flaw in it it's not with the Trompowski.

Keep in mind black didn't lose because of the opening:
Black draws by sacrificing his pawn and rook for the final G pawn. Then it's stalemate YAY
The players who play 1...Nf6 against 1.d4. What's your response against the Trompowski?
I don't like to play this position as black. if black plays 2...d5 or 2... g6 after 3.Bxf6 he will have doubled pawns (not favourable) after 2...Ne4 white plays 3.Bf4 and pushes the knight with f3 and the plays e4 with a strong ceter. and finally after 2...e6 3.e4 Be7 4.Bxf6 Bxf6 ... white's control over center won't let black try for win in a meaningful way. what is your repertoire against this line?
please answer!!
