Hi Alvin, Yes, I know that was a difficult one. I just sent it out because I thought it was rather bold of Pillsbury to announce a mate in six. I will send out the first problem in the Coup De Gras problems I mentioned last week today. These will start out with easy problems (mate in 1 move) and work up from there.

Good puzzle, but could we have a mate in maybe 2 or 3 moves to kind of work up to mate in 6 moves??

The Black King is wide open and ready to pick like a ripe peach. Chernev's solution is as follows: 22. Rxf8+ Bxf8 23. Rxf8+ Kxf8 24. Qh8+ Kf7 25. Qh7+ Kf8 If 25. Ke8 26. Qg8# If 25. Ke6 26. Qxg6# 26. Qxd7 anything 27. Bh6+ Kg8 28.

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.
