Update Richard.cpp

// This file has two parts:
//  1 - The "InCheck" function that takes a bard and a bool
//      indicating white (true) or black, and returns whether they are in check
//  2 - Below is my entire StudentAI.cs, where I have a simplified (greedy) algorith
//      being used in place of MiniMax to work through bugs on things like move validation
