There are clues in what isn't bid or played - with Curt Soloff 

Curt and Bajir, Both you guys are great together. Very natural and easy to learn video. I enjoyed watching it several times, excellent !

Love to hear these guys ... they make it easy and fun.

Congratulations!

Brilliant hand, so much learning thanks!

Always interesting and easy. Bajir

I would be happy to join with Curts lessons

East has the club queen. If West had it, he’d have enough points to open 14:11

Yes East must have QC as if West had it they would have had 12 points (AS, KS, KH, QC) and opened the bidding

East is having the queen

Negative inferences are huge in bridge - I use them all the time. This one is a common but simple example. Other common negative inferences are - when you are missing AK in a particular side suit and they haven't been lead - that means the leader probably doesn't have AK in that suit....now if they have opened the bidding or overcalled at any point that means there is a good chance the other opponent has one of the other honours in that suit. If that person has one of those honours - it might mean they are unlikely to hold a missing queen in another suit! Another one is when the opponents don't open a weak 2 in a suit but then suddenly come into the bidding showing a 6-card suit...this is probably from a holding with a poor 6-card suit...or maybe they have 64 in the majors and didn't like opening a weak 2 in a major with 4 cards in the other major. You can actually ask the opponents what they open their weak two's on. I remember asking an opponent what their style of weak 2 openers were - they looked confused when a weak 2 hadn't been bid...why was I asking about weak 2's? - lol! Another example was when opener had opened 1NT (weak - no singletons).... after 4 cards declarer could lay the hand down and announce LHO must have a singleton king of trumps as it couldn't fit in RHO hand and there were only 3 trumps missing....unfortunately my partner didn't notice this - and instead of winning the tournament in a field of 100+ we ended up finishing 7th! GRRR! I still remember that hand back in 1997!
