With 6 tricks left to play in a 3 Spade contract Ben claimed all the tricks even though there was still a trick to lose. After denying the claim and beginning to play it out, with 3 tricks left, partner robot Ben proceeds to throw away the Heart guard to keep two clubs, a suit I had bid twice thereby allowing declarer Ben to make good his invalid claim.

Ben's claim was valid, and very nice play - at that point the overtrick was 100% cold on any defence.

It's a double squeeze - if both defenders throw a club to hold onto their red suit guards, dummy's clubs become good.

It's clear to North it makes no difference what it discards (if South has the club King, you're taking the last two tricks regardless).
