Hi Chris, Good to hear it was useful. But don't get too smart until we finish our current game <smile>. Richard ----- Original Message ----- From: Chris C.

I really like puzzles like this that will make me think and in the end I can learn from. Thanks also for putting the first 21 moves in there, I actually started from move number 1 so I could understand how things got to where they were. I did end up figuring it out, but not before those old wheels did a lot of hard turning, smiles. Now only if I could have the forsight to make a plan so I could say the game will end in 6 or less moves. Thanks for everything you are doing for chess and this list!

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. Qg7# ----- Original Message ----- From: R Dinger To: chess Sent: Thursday, April 08, 2010 2:35 PM Subject: [blind-chess] Mate in Six Puzzle 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.
