A04 Zukertort Opening: Arctic Defense (1.Nf3 f6)

My games can be so problematic sometimes that the program I use sometimes refuses to analyse the whole finished game but instead it crashes every time on the same move. I have found two such games while going through my games and both times I contacted support and told about the problem and in both cases they fixed the problem quite soon on their program update. Chess is a very hard game and winning the so called won game is really difficult sometimes. You may have the winning position but if you do not know how to win the game from that position, it does not matter. I am quite likely to play some sloppy moves at those positions and give my opponent more chances than they might deserve. I did three tactical exercises today and solved only one of them... I really would need to practice tactics more. With all the games I have in progress at the moment and all the other stuff that uses my time, it is very hard to find the time to solve those exercises or rather in my case usually fail miserably while trying. I have added ten more puzzles divided in to mate in ones, twos and threes.
