My syle of play is very routine: I always play Heroes 2, even though I have Heroes III and for that matter Heroes I. I always play on the same map, with the same character, and I have a strategy that I follow fairly closely, with minor variations in how the strategy plays out. I play as a time-waster; I don't really want to be challenged to the utmost.
For a year or so, I've been able to occasionally win this scenario in 35 days of game time. On Wednesday, everything came out just right, and I managed to win in 34 days. Woot.
