Spider Solitaire: First deck stack in 13 moves

Screenshot of when I was able to finish one stack in Spider Solitaire in just 13 moves. The minimum no. of moves required is 12, but I thing 13 is quite close.

Here's a screenshot from a minesweeper session when I think I got pretty lucky.
















And this one is where I was stuck the longest (there were others too) but I couldn't make an intelligent guess about this one! Can you? Give it a shot. Which cell would you have clicked next?
