Looks like I have to save the film once more! I have to admit I find Card Player to be Argento's last enjoyable film and the best thing he did since Opera. It his take on the dutch or scandenavian dark thriller and though not a patch on his early 60's to late 80's works, it's competantly made and has some great kill scenes (and others not so). It's a fun little film, quite out of Argento's comfort zone but he delt with it well. Yes, I prefer it to Sleepless, Trauma, and Stendhal Syndrome. And it's miles better than Giallo and Dracula.
