comment I can't find the Nash equilibrium of this 3x2 game.
Forget the equations for a minute and think about why Henry's answer is correct. Remember: a Nash equilibrium is a pair of mutual best responses. Equivalently, a pair of mixed strategies are an equilibrium if and only if all pure strategies played with positive probability are best responses. If player 2 mixed uniformly then player 1 gets 0 from the bottom two rows and (always) gets $a>0$ from the two top. Against the top row, player 2 is indifferent (so any mixture is a best response). Thus this is an equilibrium. Use banach.lse.ac.uk to solve games and refine your intuition.

revised Prove two person gerneral sum game , the expected payoff cannot be lower than safety level.
The previous definition of safety level was imprecise and thus confusing - see, e.g., the comment. Removed this part, which leaves a well-defined question, since "safety level" is a standard concept.
