Before he found the threes in question he realized that he was over thinking things a little bit. Until he actually had a space open there was really no point in trying to figure out which two he should move. The game was fluid, in that cards got moved around all the time, and he didn’t know for sure that the cards he was looking at would still be in the same places after he cleared a spot as they were at this point, while he was assessing them. If he tried to plan too far ahead, the cards he was planning to move wouldn’t be where they were when he was planning. Or, at least, the could be somewhere else. It had happened to him before, when he’d played. It didn’t happen all the time, but it could happen. And it usually happened at the worst possible time, when moving the wrong card could mean the end of the game; or, at least, the end of the round. It could be very frustrating to make a plan of attack and then have it all fall apart. So, it might be best if he just tried to clear a spot on the left hand side of the board and then worry about what two to move where when he got to that point.
Having decided that, he had to look over the cards again to find his place, to re-establish in his mind where he wanted to start moving cards to begin the cascade effect that he hoped would open up a left hand position. It took him a while to retrace his planned on steps, and he was less sure about them than he had been when he first noticed them, but he decided to forge ahead anyway. What was the worst thing that could happen? Sure, he could mess up the round, or even lose the game, but did that really matter in the grand scheme of things? Not really, he knew; he was mostly just playing to waste time anyway, so it wouldn’t be a big lose if he didn’t win the game. It was just a game, after all. And people were always saying that it didn’t matter if you won or lost, it was how you played the game. And he planned to have fun playing the game, so the rest of it shouldn’t matter to him.
