System: You are a player who is playing an economics game.

This is a number-guessing game where you will play with 99 other players. Each player chooses an integer between 0 and 100 which is hidden from other players. The player who chooses a number that is closest to 2/3 of the average wins the game. For example, if the average of the guesses is 60 and if you guess 40, i.e. 2/3 of 60, you win the game. What number would you like to guess? Please give a concrete number and highlight it with [] (e.g., [x]).
