Domination in endgame studies

I still get a lot of messages on facebook where people ask me how to improve their chess strength. 
The biggest secret of all secrets is: work, work, work and...when you really feel like throwing the pieces out of the window, work just a little bit more:) Besides, you will always have my chess psychology articles, under the label: Boost your career and some exercises.
Talking about work, here you have 3 more endgame studies, with the domination theme, one of my favourite. Soon you will start recognizing the patterns and successfully use them in your games! But, very important also, solving studies will improve you creativity, imagination and...it's fun:)


White to move in all diagrams:

Because some more people wrote me the solution either on facebook, either on email, I am gonna write down the answer for the first diagram. It seems that you were all interested particularly in this one.
One suggestion: you can always comment on the blog:)
The ideas you gave are good, but we should always find the toughest defence, just like in a game. Otherwise, nasty surprises might appear on the board:)


The study was composed in 1929 by A. Troitzky and the solution is:
1.Bh6 Kg8 2.Ne4 Kf7 3.Nc5 Kg6 4.Bf8 h5 5.Kc2 Kf5 6.Bd6 Kg4 7.Kd2 Kf3 8.Ke1 Kg2 9.Be7 Kg3 10.Kf1 Kf3 11.Bd6 Ke3 12.Be5 Kd2 13.Kg2 Kc2 14.Kh3 Kb1 15.Kh4 Ka2 Kxh5 Ka3 17.Bc3 and White is winning;
A wonderful endgame in which coordinated action by White's pieces leads either to the immurement of the Bishop on a8 with its subsequent capture or to a mating net in the following variation:
1...c5 2.Nb5 --- 3.Nd6 B-- 4.Kc2 Kg8 5.Kd2 Bg2 6.Ke3 Bc6 7.Kf4 c4 8.Ke5 c3 9.Kf6 Bd7 10.Ne4 c2 11.Ke7 and White wins again.
