That is completely the wrong approach to chess. You should be playing to get good positions. If you learn how to maintain an advantage, how to win the won game, you will get many wins.
One trick ponies that are unsound might get you a win here or there, but for every one of them, you will get 5 cases of a terrible position and lose most of them.
Not worth the trade off.
Problem with the old Benoni from your first post is that the Benoni is not very good if White has not played c4. This is why everybody now plays 1...Nf6 and only after 2.c4 do they play 2...c5.
Reasoning is simple. In the Benoni, Black's biggest weakness is the d6-pawn. After 1.d4 c5?! 2.d5 Nf6 3.Nc3! (No c4) d6 4.e4 g6 5.Nf3 Bg7 6.Be2 O-O 7.O-O e6 etc.
Both sides can alter move order, slight change in moves, whatever. The main point is that White will eventually play Nf3-d2-c4, and with that Knight on c4, White gets a pretty big advantage.
Compare this to the Czech Benoni, 1.d4 Nf6 2.c4 c5 3.d5 e5 4.Nc3 d6 5.e4 Be7, White has no open c4 square for a Knight to harass d6.
There are plenty of SOUND defenses to d4, and some have numerous variations within that no White player at the Amateur level will know all of them:
QGD - 3...Be7, Lasker, Tartakower, Orthodox
Slav - 4...dxc4, Semi-Slav, Triangle Defense
QGA
Nimzo - 4.e3 you have 4...c5, 4...b6, 4...O-O, with 4.Qc2 you have 4...c5, 4...d5, 4...O-O, with 3.Nf3 you have the Queen's Indian, Bogo-Indian, Modern Benoni, or QGD
King's Indian - Against the Classical you have 7...exd4, 7...Na6, 7...Nc6. Against Saemisch you have 6...c5, 6...e5, 6...Nc6, 6...c6, etc.
Grunfeld - Ask others for advice on this opening
Modern or Czech Benoni
Dutch - Classical/Stonewall, Leningrad
With all of these sound responses, there is no way your opponent knows all of these. With sound lines, one slip-up by the opponent can often lead to a big advantage for you.
One trick ponies are just that. Most already know the Budapest trap. Many know the problems with the old Benoni and will play for Nc4 and a4 (to prevent b5 and keep the outpost for the knight). These disaster lines will lead to just that, disaster!
I COMPLETELY agree with you. I used to play these people OTB and they would slam pieces every time they move because they’re playing something “unorthodox”. They’re doing this because they think they’re doing something good and catching me off guard. I found it very funny.
Yes, that's what I played from the white side too. But it may not be best. That line allows black to pin white's knights and achieve an asymmetry he is looking for. I've been caught out a few times, and possibly because while black was playing "his system", I was playing a rarely visited part of my repertoire. My venture in Chigorin territory occurred after a recent loss and memories of the other games.
From the white perspective, developing both knights and letting black play dc could be better...
