It might seem to be to simple, but don’t underestimate the power of boredom and curiosity. The new player won’t know what you’ve been folding the whole time and will have had nothing else to do but call a sudden change in behavior to see what you have, or fold and keep the pattern going.

One player (beginner) wants to have fun (maybe not overtly, but this is usually the case), the other wants to make money.
