The tendency
Leo players want control of every game they play, and though they will not admit it, they want the attention that comes with it. If you make a mistake that would cost you a piece, a Leo may suggest you take it back. That generosity is really control, and it can backfire and cost them the game. Afterward they may feel they let you win.
Temper is the other risk. Leos who lose patience make impulsive moves and will sacrifice a good piece for a small gain.
