Wow! thanks for quoting that thread, I had completely forgotten about it and there is indeed some good stuff there.
Here is what you need to know about the Tromp in a nutshell:
1. The Tromp is very dangerous for Black if he gets too frisky.
2. If Black meets the Tromp with either 2...d5 or 2...Ne4 3.Bf4 d5 then there is very little to fear theoretically. Trendy at the moment is a weird line dubbed 'The Raptor' a cool sounding name that conjures up images of a dangerous predator, but like GM Sam Shankland I too tend not to take Openings coined after animals [or reptiles] very seriously. The Raptor goes 1. d4 Nf6 2. Bg5 Ne4 3. h4!! or some enraptured [Pun Intended] players insist with 1. d4 Nf6 2. Bg5 d5 3. e3 Ne4 4. h4!! [Exclams for cajones] Everytime I see and study such games in my database I think to myself why not me, why can't I find opponents who engage in this kind of thing. For the record Avrukh's published 2012 antidote against 'The Raptor' remains as reliable today as it was way back then.
3. All lines for Black other than what I outlined above allows White the potential to have too much fun and too much initiative. A bit of advice, don't let the engines give you a false sense of security in irrational positions, aim instead for rational positions that are easier to play and more importantly understand. To illustrate these points, take the following position:
1.e4 e5 2.Nf3 Nc6 3.Nc3 Nf6 4.d4 exd4 5.Nd5 Nb4 6.Nxd4 Nxe4 7.Nb5 Nxd5 8.Qxd5 Qe7 [Many sources stop here and claim black is much better]
9.Nxc7+ Kd8 10.Bf4 d6 11.0-0-0 Kxc7 [At this point the engines love Black's position, and perhaps in a higher sense this maybe ultimately justified, but in over the board play there is no way I'm heading for this mess if I have a safer option that offers decent chances. For me King safety trumps all, even Stockfish

Hopefully Mr. Palliser himself will soon weigh in on this topic either here or in a future update. We can dream after all, can't we.
