Endgame puzzzle - white to move and win. Can you find out how?

This looks completely lost, isn't it? lichess.org/sfgHcyc3 Yet, you can win it against stockfish 8. Go here (lichess.org/editor/8/8/8/1q6/rB1r4/8/2KN4/k7_w_-_-_0_1) and pick play against the computer.

Oh, and for anyone who considers the above challenge too simple, you can also try this lichess.org/editor/8/8/6q1/8/2N1r3/2K5/5R2/1k3r2_w_-_-_0_1

First one I took 5 seconds to solve lichess.org/XYrXmRkG/white

Nice Puzzle!

Second one a bit tough...took me three minutes

@Smasher49 congratz on beating them both. 2nd one was meant to be a lot harder :)

These aren't really "endgame puzzles" (they are set mates).

@SynapticSentinel
The Puzzles are just hard in Comparison.

@MrPushwood , I think rather then calling them set mates, a better name for them will be, Compositions.
