Intuitively, shouldn't every card preflop have roughly the same likelihood to hit the board? We all have stories of aces getting cracked etc.

I guess my thoughts are playing a junk hand for cheap is at times a good move, whether for bluff value or to hit a big hand when it is not expected. If AK or something scary hits the board obviously you are out, but if you played unlikely cards but caught a nice, unexpected piece of the board, that should set you up for a nice pot.

Is my thinking wrong on this, or too -EV long term to be viable?
