Chess: You MUST stay alert!

In my last club game, my opponent gifted me with a huge blunder! I think he was guilty of one major fault. He had one and only one plan in mind and he was intent on sticking to it regardless of anything else ... In fact he became so blinkered by his plan that he left a piece hanging and I cleaned up.

After making some horrible opening faux-pas (moving same pawn twice - what was I thinking?), I made an effort to concentrate and then he blundered by playing 12.g3?, therefore the game is not at all noteworthy. The technique I used to keep him from using the open d-file for either of his Rooks was correct though!

As usual, any comments welcome ...
