Game analysis

ended up quite low on time.  my opponent was moving pretty quick throughout, but I spent a couple minutes on the opening and then probably about 4-6 more minutes during the thick of the attack - moves 19 through 21 looking for a mate, after 22.Qh7 I picked up the pace, but still probably only had 5 minutes to his 11 or 12, and then a few more minutes spent on moves 26-30 left me with 2 minutes to his 10 when he resigned.  I thought he still had plenty of chances left.
