Also I'm confused about the two stranded white stones in the lower left that appear later on. According to "4 in a row is alive" concept I assume my group (black) in the lower left is alive? The program seemed to change it's mind frequently on whether it was alive or dead.
Let's discuss this. The first point is to realize that a situation might be left unresolved at the moment because more valuable to play the move elsewhere. In other words, it might take one more move to live or one more move to kill (eventually) but at the current stage of the game that group isn't worth two moves. The TIMING of when to resolve something left behind is one of the things you will be learning as you improve. Does THAT explain the program (or a human player) changing mind back and forth? You are asking about the life and death of the lower left corner, but white is after much bigger fish.
OK, now let's look at that corner. If it is black's move, do you see a move that will DEFINITELY make that corner alive? If so, now instead assume it is white's move. Is the corner still alive if white made that move? Four in a row might be alive, but not "bent four in the corner".
You apparently have MFOG 11 available (this is the pre MCTS version, capable of up to about 6 kyu, can be told to "randomize" so won't always make the same move) It has a mode where it will throw life and death problems at you. Have you begun using that?
