Hello Blind Chess Puzzlers,

The following was taken from the book "Logical Chess, Move by Move" by Irving 
Chernev and may prove to be an interesting chess puzzle.  The position is from 
a real game between Pillsbury and Marco.

This is the Forsyth diagram after move 21, note that each Rank is on a new line 
to make it easier to read:
5rk1/
1b1qb3/
r4Rp1/
p2p2B1/
2pP3Q/
2p1P3/
PP4PP/
5RK1/

White to move.

At this point Pillsbury announced that he (White)has a forced mate in six moves 
or less.  Can you find it?  I will reveal Cherneb's solution next Monday if 
nobody solves it by then.  Note that Marco (Black) has a Pawn just 2 steps away 
from royalty.

If you are interested in how the game got to this point, I have included the 
first 21 moves below and hopefully I have converted from descriptive notation 
correctly.
