I doubt that is due to any superior 'yomi' skill on your part. The payoff matrix is simply in your flavor.
Mushin a junebug, advance.
If they run: They lose the game.
If they don't: You spent 3 clicks and a cred.
I'll play that coinflip all day long. You only have to win once.
It'll always feel like you are the double genius chessmaster when you play with odds like that.
Rusemaster General Walter mushin's an overwriter.
They run: Muahaha, I spent 4 creds to do 4 brain damage. Game is over as soon as the roflcopter delivers me a contract killer and a dedication ceremony.
They don't run: Muahaha, as soon as a dedication ceremony and back channels shows up I'm getting 21 creds for 2 creds and 4 clicks of work. Further, they may well run it eventually anyway, just to make sure it isn't a ronin or whatever.
It's easy to feel smart when you are winning with a garden of mushin style deck, but that's just an artifact of the information imbalance.
The games you lose are the ones where they decline to play your reindeer games and just run a medium train on you, but even then you can convince yourself that you outsmarted them when they hit some toxic red cards and die.
Poison decks always feel like you are tricking the runner, since their deaths come about at their hands and/or your score outs happen in uncontested servers...and in a way you are, but it is a way aided and abetted by the rules of the game. Netrunner lets the corp install stuff, and it has given us toxic cards. PU increases the penalty for being wrong, so shell game are attractive.
It isn't mind reading to shit out 3 remotes, 2 of which are bad and one of which are good, and crow when they hit a psi field or let a HoN score. It would TAKE mind reading on their part to take the path to victory.
Don't fool yourself. You can't read people's minds. People have trends, "Everyone bites at 6 advancement counters vs a green deck cuz they don't want to be the clown who lost to a slow rolled gov takeover", "People'd rather lose to a trap than watch you score out because they enjoy feeling active, so they'll check much more often when you are on match point", etc, but there isn't a way to know which of these trends are true about which stranger.
