You won't Blitz it mate, I used to think the 75 minutes we have for 36 moves in our local league was a ridiculously long amount of time, now I find the two hours for 40 that are more common in the congresses I play a much more enjoyable time control. Even that is only three minutes a move. As I play Kings Indian a lot, i tend to rattle through the openings 6 or 7 moves. But when you think you need to consider what your opponents move has changed, any new threats or weaknesses he's created, you need to consider whether you have a plan to exploit or defend those changes, decide what 2 or 3 responses are reasonable, then think what your opponents response would be to each one, consider the 2 or 3 resulting positions, and decide which one you prefer. And you need to make a final blunder check before making the move. I don't do all these things every move, but it is something I need to do if I'm to get better. Other things I do when i notice I have a fair bit of time on my clock or when I don't know what to do next is look at every possible capture of mine or my opponents, queen and piece saccs etc, and see what the response would be. I also look at pawn pushes and the possible responses, forks and of course, check all checks. I really do need to put in place a proper thought process, but I suspect I'm too lazy.
My OTB play is much better than my play here, I do tend to play RHP like Blitz chess, look at the position and move, unless I have someone who's moving quickly, in which case I'll set it up on a board and play like a proper OTB game.
