White to move and mate in 5
This is a problem by Sam Loyd. The story goes that someone was bragging that they could tell at a glance which piece would deliver mate in a chess problem. Loyd composed this puzzle and asked the chap which piece he thought least likely to deliver mate and bet him dinner in the process. The guy ended up paying for dinner.
So if you want a hint in solving this puzzle you could ask yourself which you think is the least likely white piece to deliver mate on move 5.
