TMA (White) and TMD (Black) - completely new openings!

Today I discovered a new(?) type of setup, both with White and with Black against d4/c4 (does not work well against 1.e4).

The starting position with White is reached by 1.Nf3, 2.e3, 3.Be2, 4.0-0, 5.d3 and 6.Nd2!? with ideas of c4 / e4 / f4. Often a4 to block Black from expanding queenside, and sometimes enabling a knight on c4.

Starting position with Black is 1.- Nf6, 2.- e6, 3.- Be7, 4.- d6, 5.- Nfd7!? -- same ideas, although delaying castling kingside in case of White castling queenside.

All views/input welcome, refutations also! :-)
Maybe this setup is known? I haven't been able to find it though...

Two studies that will be added to:
lichess.org/study/6SxVnN4l (TMA, White)
lichess.org/study/8iwAuRMl (TMD, Black)

Some games:
(Classical game, first serious game with this setup that I know of -- ACPL below 20 for both players)
(ACPL White: 22, Black: 42)
(ACPL White: 25, Black: 63)
(ACPL White: 43, Black: 71)

The TMA-study has been updated with four engine games, 3 draws and 1 loss. Thanks to @gonzothesmurf !

It's certainly not unplayable, but I don't really see the point of this system.
In the TMA, White offers Black to take the initiative and what exactly does he get to show for it?
The TMD on the other hand looks like a Modern Benoni (A60) if Black plays c5 or an Old Indian (A54) if he plays e5. In the former, he develops his bishop to e7 instead of the usual g7. In the latter case, he has lost a tempo by the double step e6-e5.

Interesting note: White sooner or later plays Bf3 in all three example games (twice in move 8 already). That does ask the question: Why not play a KIA and fianchetto the bishop to g2 in the first place? This is the question you have to answer to show that your system has its own merit.

Indeed it is like an Old Indian Defence or an Old Benoni Defence, i.e. with ...Be7 instead of ...g6 and ...Bg7. Omitting ...g6 avoids the weakening of the king's position and thus prevents attacks such as h4-h5 or f4-f5. You can also castle one move sooner. On the other hand the bishop is more active at g7 than at e7. In the Closed Ruy Lopez black also often plays ...Be7, ...o-o, ...h6, ...Re8, ...Bf8, ...g6, ...Bg7. In a closed position the loss of tempo is not that bad.
As white TMA it is surely playable. I am not sure if TMD is playable as black. Especially the move Nf6-d7 is contrary to the principles of development and thus cries for some active refutation by white. Nf6 is already developed and Nb8 is not. Moreover with Nf6-d7 Nf6 abandons its defence of the king's position.
The computer games where white plays the TMA do not reveal much. Computer games where black plays the TMD might shed more light on the subject.

Thanks for your thoughts, and I think that the main point of the setup is primarily psychological - it is playable although the setup is quite strange. In faster time controls, your opponent is often used to having an opposing knight on f3/f6 so they need to change mindset (which is not easy in quicker games).

The LSB on e2 actually prohibits Ng4 and in some variations it can be exchanged for a Black knight, and with a pawn center on light squares the White DSB can become really strong. After Re1 it can go back to f1, also guarding d3. I think it resembles some variations in the Sicilian with the bishop on e7.

What I do like about the setup is the possibility for new pawn formations, I haven't seen too many openings where the pawn chain is a2-b2-c4-d3-e3-f4-g2-h2 but here it actually might happen.

I also like that White can either play c4 or e4, he is not limited to 'just' one choice - as in the old indian/benoni lines where the centre gets locked pretty much immediately.

This is (if white plays e3-e4) an Old Indian/Philidor setup with minus tempo (e4 played in 2 moves) or (if white plays c4) a Benoni where the Be2 would be better placed on g2.

Yes, but also: 1) White can choose setup accordingly, 2) the Knight is on d2 instead of f3.

Is it worth two tempi? Theoretically - probably not, but in practical play it has at least psychological value as well as creative possibilities for the two knights. In case of a closed center the bishop is actually ok on e2 I think.

The first thing to check is if the opening is good against a four pawns setup. This seems not to be the case:



Black is better already.

Another possible Setup is a fianchetto setup:



This is also good for black. There are many other setups where black has no problems.

This is too passive, white must fight more actively for the center squares.

Too weak, too slow.
