Had these two things happen to me at the First CASLO, (Canadian ASL Open) that I ever attended.
At the end of my first match, I was down to my last half squad and needed to get one building in my original setup area. My HS was locked into melee with two squads at 2-1 odds against, 1-4 back. It was his turn and he rolled first. He tossed boxes and I withdrew out into an Adjacent building that was in my original setup area. Game over.
Later in that tournament, I was playing a DFB scenario The Forests North of Karachev I believe was the title. The exact VC escape me, but I was in deep excrement again. This time yet another melee was going on, a hero and a gun crew vs 3 squads and a leader. My opponent again obliged with a cars and I scooted the crew out and left the hero behind to keep the Huns busy. He withdrew onto a malfed arty piece. In the Russian turn that followed he fixed the Gun, pivoted the Gun and managed to hit what he was aiming at, a large German kill stack, with a round of smoke. The mods for shooting out of the smoke helped the Germans miss their key shot and gave me the game. My poor opponent just sat there shaking his head muttering "unbelievable" again and again, before turning to his son and saying "This is why you never give up in this game".
Both of these guys were good sports and I really loved the triumphant tone in my second opponents voice as he instructed his son. I got the feeling that topic had been discussed by them before. Gotta love this game.
