Our club tournament games are of higher quality and better disputed, but still we are missing way too many opportunities to apply what we are doing in class. Will repeat over and over again: each move needs to be treated with seriosity. Analysing the position every time will help you find the solution in most cases. Instead of doing this some of you are either bored, or distracted, or simply going over a situation too fast and missing the important (and sometimes obvious) possibilities. You are given sufficient time to play your games and I would rather see you losing some on time, but playing correctly!
Today's puzzle is a good preparation for next week's test about the IQP. It also is a good opportunity to practice and improve your analysis. Your tasks:
a) Analyse the position and come up with plans for both sides
b) White to move and win

Total available points for this puzzle is 20. The answers will be published next week together with puzzle #109.

Puzzle #107 solution:
Our game under microscope was Tolush - Flohr, Pernau 1947. This time I liked a lot Humphrey's work because he finally has put more effort into it compared with other times. He has the floor:
a) The opening's name is called Torre Attack, Classical Defense
b) Analysis:
The material is even.
White has a safer king because Black didn't castle yet, so its King is still in the center and White could start an attack against it.
White could start by attacking the Black king that is still in the center (taking advantage of the King in the center). White could start attacking because it has already castled. White could open files to the Black King and attack it.
Black should first castle before attacking to keep its King safer, then attack the White King.
