This is a position from a competition.
It is white to move, can you see how white can force a win....
White actually played Q x f7 +
Black only has 2 options, move the king to h8 or take the queen with the bishop.
Both options loose, can you spot why.....
If | ........ | Kh8 |
then | Qf8++ | |
or if | Bxf7 | Rd8++ |
