Day 215 / 150 to go

This evening I contnued with Soltis ebook and puzzles/motifs on how to drag defenders away. As already indicated, the amount of diagrams and positions to solve is great. Here´s a nice one (Black to win):

In addition, I continued with Smith´s book and reached some exercises there - I did the first three and got the moves right but not the variations properly calculated: I was simply too tired. So I decided to stop. Assumingly, the daylight saving (clocks changed last weekend) is yet "disturbing" me...
 I prefer to continue once I am fit enough and not tired in order to get the solution 100% straight instead of just identifying the correct theme/first move...
