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.
