At recent tournament game, I watched two antagonists battle it out. 

One player sensing the tide going out of his game, offered numerous draws, each of which were spurned by his opponent with a look of contempt.

To prove his point, the player with the dominant side promoted each of his remaining pawns to bishops(!) when he suddenly discovered he had carelessly created five dark square bishops with no complementary pieces with which to control the light squares:

Fortunately for white, a win was still available; Can you find it?

P.S. I was kidding about the "game"; this is a brilliant if impractical composition by Troitsky (1905).

WOW

Nice use of the bishops

why the fifth move must 5... Kxa1 ????

If  5.... Kb1 "can this mate to???"

great puzzle!

Good question!

Let's take a look...

After 5. Kc3, Kb1 (instead of 5...Kxa1)

the position doesn't deserve to be considered seriously.

That certainly is one opinion.

I look at the incredible output by the genius Troitsky, and certainly cut him some slack for fantasy compositions.

I also think some people take chess far too seriously. 

OK....really good puzlle....

Love to see another again

uh this is a random puzzle

wow amazed me completly. nice use of bishops
