This article is an introduction to both two-person zero-sum and two-person non-zero-sum games. Two imaginary firms A and B are introduced. The firms compete for market shares. The fundamentals of two-person games are described in the framework of searching solutions to examples of the competitive situation between the firms A and B. Advanced mathematics is avoided.

The games and the solutions are:

• Two-person zero-sum game
  • pure strategy
  • mixed strategy
• Two-person non-zero-sum non-cooperative games
  • non-existence of solution except in special cases
• Two-person non-zero-sum cooperative games with repetitions
  • Nash's solution
  • Shapley's solution
  • Nash "threat strategy" solution
  • Raiffa's solution
  • Braithwaite's solution
