Actually, I also missed the point it was MPs. At MPs you might not wish to double, on grounds that if they go down you'll get a good score anyway, while if they make it, it's a rock-bottom. At IMPs it's ok to risk the occasional 4♠ X just made (couple imps lost), to try and get a substantial set (loads imps) if opps are overbidding. Of course, it may happen they redouble and you're kinda in trouble, but they would never redouble if you double with conviction :lol: Substantial what? You have a math problems At Imps If double is wrong from 420 to 590 lose 5 imps from 450 to 690 lose 6 imps and if they redouble you lose a zillion imps If double is wrigth From 50 to 100 you win 2 imps From 100 to 300 you win 5 imps And if you think 500 is possible here I strongly doubt it. Substantial win of imps? What?
