Draws by fortress and stalemate
Some time ago I looked with the old chess master at some endgame studies, a dozen of draw ones.
A fortress is a chess feature which might not be known very well by beginning chess players, but can come in very handy to make a draw, so I'll give some examples first :
Fortress example 1 :
White has a queen against rook and bishop and two pawns.
White will be unable to win easily here, as black has a fortress, and black could try to play for a win instead.
