Carreno's Entropy is a two player game played on a 5x5 square board.
Notice that a player can put himself in check, and remove it on the next turn, if he wishes so...
Black stone at c5 is in check. A possible play is to move a4-c4 in order to remove it.
what is the best move?
White is threatening to win at d2-e1, but is Black to move (both samples by A. Carreno)
Black can avoid this by moving b2-b4, which denies the c2 stone its connection
