Good to see the engine-killer back in business with these amazing compositions. 
And this puzzle makes me feel quite good about myself, for once I scored 100%!

Well my friend, you're doing better than Stockfish on this silly puzzle!
For once I had 1 back from the mighty Fish. It feels so good.
And I do not think the puzzle was silly at all. It has good humor to it, yet it is a challenge nevertheless. So thumbs up!
This is a pretty amusing and simple Mate in 13 that seems to trip up SOME engines, but not all. once you see the solution or solve it yourself you might get a chuckle out of it.
