A couple tips to avoid stalemate:
When you have positions with an excessive material advantage, stalemate can often be very close by. A couple ideas...
1. Play by continually giving check
2.(My preference) play as if you only have a queen and king. That's sufficient enough to give checkmate, and so you can spend just a few moves clearing the other pieces away and just focus on the position as if it's striped to k vs kq.
For example on move 68...you can go Ne2 Bh1 and just work with your king and queen to give checkmate.
As for an answer to your question...ImprovingSkill's suggestion is a good.
