A bit of a "you had to be there" moment, but it was my win at a tournament that was down to Kill points and Dawn of War.  I turned a loss into a draw.  My opponent was playing Saim-Hann Eldar (Jetbikes and Vypers) In the last round, we were tied 1 to 1, because all our shots were highly selective.  He had destroyed one of my Rhinos and I had destroyed one of his Vyper squadrons.  In the last round, his Farseer and Seer Council flung all their Singing Spears at my Venerable Dreadnought (S9) and there were 6 being thrown.  They were guided so 4 wound up hitting, 2 dice came up as "Explode" but being Venerable I asked for a reroll.  At the end he was only immobilized and the game ended.  Without that roll, I would not have taken Best General at that tournament.
