White to Move© (The Turk's Tactics Thread)

And indeed that end looks (!) simple if the pieces move in front of you, but I have never tried it/have had it in a game myself.

I liked this one:

If this is correct, and if I was a sub, I'd rec this.

Difficult to read through. Quite dense! Ah, the 'bolding' makes it better.

The main variation is correct. Note that 13. Bf6+ mates in a similar fashion (13. ... Kf8 14. Qe7+ Kg8 15. Qxg7 mate). It seems your subvariations are correct too - your turn.

I used ChessBase to keep track of all the variations. I don't have a slick way to translate it to RHP yet, though; hence the many edits.

Next problem:

Mate in 4

Composed by a Dutch, no? Let me try...

I don't often get the chance to see such wonderfully written answer to a puzzle.

Well maybe BigDoggProblem's answer here - Thread 56729 is also good.

When did chessgames.com changed their interface? It looks much better for the eyes compared to old black and white!

Thank you very much. Did you recognize the position or did you "Google" this?

I've seen it before here: http://www.logicalchess.com/resources/lessons/tactics/toughest/index.html
(The "4.Had enough" link), where the game is quoted. Then it was just a matter of searching in the databases for any games between the two players.

Not composed by a Dutch but by Vukcevich (1982). Very nice. I couldn't solve it myself... I wonder if anyone else can find it?

May I give a hint? Discovered check and Bristol theme...

You might as well have just given the full solution.
