I was playing regular spades and had a pard who decided I wasn’t playing right. Why? Because the opponents were in the lead by 100 points and had 9 bags. The total bid was 11. My bid was 1 based on having just 1 heart and the K, Q of clubs and 1 spade, the 4. Clubs worried me because I had 5 with the 6 as low so didn’t want to risk a nil but wasn’t sure I would even get 1 out of it. Thus I was actually bidding on the fact that I had just 1 heart. I the King of hearts as the loner and so I led it right off the bat and took the trick. I figured my partner had the Ace. So I led the Q of clubs and West snagged it with the Ace then led the Ace of hearts. Hmmmmmm I grabbed it with the 4 of spades. Then led back the King of clubs fully expecting it to get cut. My partner let it go by, he was out. But then he commented “What are you doing? You bid 1″. I didn’t reply but he took realized that they had over bid and were trying to play the bag game too.
We set them and there they were, in a very familiar scenario, suddenly behind with 9 bags. I let my pard know that he shouldn’t question my playing. 
Next hand we nailed their bag and it looked like smooooth sailing to the win.
But it got worse. The next hand I had 3 diamonds, king high. The A of clubs and the A of hearts. 3 spades with J high. So I bid 3. Pard bid 1. They bid, being baggers, team 6. My A of hearts flew. Then I played my A of clubs and it got cut. Opp then led the Ace of diamonds and lo and behold, his pard was out of diamonds. I was screwed. I tried to fudge my tricks in there, hoping my partner had underbid. No such luck. We took 2 tricks (pard’s only trick was A of Spades. His only spade.) they took 11 on a 6 bid.
We were now at 396 to their 425.
They did a team 6 bid. Hmmmm. My hand could take 1 and my pard was bidding 4. So I went for it. Nil. My pard then said the dumbest thing. “A nil won’t win it for us, you should have bid” I replied “For 1, a nil IS a bid. Second, it WILL win it for us. 3rd even if it didn’t win it for us it would put us in the lead” . The opps thought they were being clever when they ran him out of spades. Too bad I only had 1 spade so I was able to dump that pesky Ace of clubs and a few other high cards and make my nil. We won. Pard said “You are such a bad player it was only luck we won” then he left before waiting for a reply. sigh. Yup. I’m so lucky that I have an 80% win rate with total strangers.
He was feeling bad for questioning everything I did and then seeing I was right.
