Re: Chess Puzzles
Hi ganesh;
I won't hide the answer because no one is checking this topic anymore.
Answer to 33:
Generally an expert player (rating around 2000) could easily force mate from that position in under 50 moves. A grandmaster (rating about 2500 - 2600) could force mate in that position in under 35 moves. Most computer chess engines can do it in around 30 moves.

Re: Chess Puzzles
Hi ganesh;
A smothered mate is delivered by a knight to a king that is totally surrounded by pieces or pawns. This is a short example:
1.e4 c6 2.d4 d5 3.Nc3 dxe4 4.Nxe4 Nd7 5.Qe2!? Ngf6?? 6.Nd6 mate.

Re: Chess Puzzles
#34. If a king is on the same line as a piece that can threaten it in that direction, but has one of it's own pieces protecting it, that piece (the protecting piece) is only allowed to move to squares on that line, if the enemy king is in a place where it is threatened by the protecting piece, the protecting piece can't capture the king because that would put it's own king in check, so is the the king (enemy king) in check?

Re: Chess Puzzles
Hi johnkv;
Ans 1 is not that simple.
1. On an empty chess board, place the knight on any one square. Cover all the remaining 63 squares in exactly 63 moves without moving to the square you've already been in.
(a) Can this be done?
(b) If so, how?
Here is a knight tour. Start at 1 and each successive number is a knight move.Each square is covered once and only once. It takes 63 moves.
