Somehow, I had trouble with this one, even though my opponent’s rating is only 1210, I felt she didn’t let me off the hook until the endgame. I was under a minute when she had an hour; again, it literally read 1 on her clock for one hour, and I was under a minute. But it got really easy for me in the endgame when it wasn’t as clear for her what to do, and then she started blundering, and then the endgame skill/knowledge just sort of kicked in for me.
29.Qf5+? A mistake right before where a 30 move time-control could be. I was angling for a queen trade in case I couldn’t find a mate, and I already knew I wasn’t finding it. So with my 1 minute to her 1 hour, I finally throw away all I had gained with that extra hour spent. The mate is 29.Qxc7, defending h2, which I had missed, followed by a Qd6 mate move coming up shortly.
30.Qg5? Okay, this is actually where I throw away the advantage. 30.Qe5+ Kd8, 31.c5 keeps the queens on the board, and is winning, but there are tricky tactics that I have to watch out for, since the mates are now all his and no longer mine.
