I don't get using pseudo-random number generators to dictate play. It seem like it's more +EV to simply use table image, table texture, villain tendencies to in essence 'randomize' your play, throwing off anyone who may be attentive enough to exploit subtitles in your playing style.

This of course won't work on anyone who's astute enough to notice your adaptations, also noticing the same factors that led you to your adaptation leading them to profile you accordingly, but honestly -- if villains like that exist below high stakes, it's in such a low frequency that I'm inclined to give it to em'.
