Been playing the Trompowsky now and then and already have two books on this opening ("Winning with the Trompowsky" from GM Peter Wells, 2003 and "The Trompowsky" from GM Joe Gallagher, 1998). I only found 4 games in the Chessbase MegaBase 2007 where GM Nigel Davies actually played the Trompowsky (A45) - two wins in 1998 and two draws in 2000 (the wins were against much lower rated players than him).

Atleast GM Gallagher played 14 games with the Tromp (68% wins) and GM Wells 31 (66% wins of which one against GM Shirov in 2006, blowing the latter off the board in 13 moves!).

I'll just keep the books I already have and look up games by GM Adams (47 games with the Tromp, 62% wins), GM Wells, GM Gallagher and, maybe best of all, GM Igor Miladinovic (118 Tromps and 75% wins!).
