@ClavierCavalier: Presented as a puzzle, but actually a situation that was once a position in a game. May be the word 'challenge' should have been used instead of puzzle. If it is a puzzle, I agree with you.

@wafflemaster: I agree, but I would disagree that a move like Qf2:+ would be part of the combination in a game. If someone would tell me this move after a game, I would ask him 'are you serious?' It is like saying 'check' to your opponent. You don't, do you? I would count it though in the combination of a study.

@browni1341: No, it is a mate in four, because at page 5 there were four people reacting on my post.

@eddysallin: mate in 6, 7 or 8?

1 was difficult; took me a few minutes, but 2 was simple and only took a few seconds.

Thanks SmyslovFan for your comments and for pointing me a direction to improve my rating. I will try to figure out what 'incorporate my tactics skill into my games' really means. 

first one isn't mate i 4 either. Black isn't forced to take on g6 and has the zwischenzug with Qxf2 making it a mate in 5.

25. Nf5+, Kh8, 26. Qxg6, Qxf2 27. Kxf2, Rf7 28. Qxf7, X 29. Qg7#

I loked at the players for the first one and played the least likely move that I would play, and it was correct 3 times in a row. Second one was well played by you, show off!

Easy problems. The first one is a good problem... I had already solved it earlier.

Ah, right on time!  Good job.
