Sacrifice or not ?

It is heartening to see every E-W pair bid to 4S on this hand.

East opens a weak 2S and West with good shape and a 5 cd fit bids 4S.

How many in the South seat competed with 3C vulnerable ?

Who wouldn't with their own good suit and a marginal opening hand.

The spotlight is now on North, pass 4S or sacrifice in 5C?

2 down doubled is -500, still better than 5S scoring -650.

North uses Loser Count to make an educated guess.

Typically, a balanced hand with 12HCP's has around 8 losers.

South's hand has about 6 losers. North's hand reduces this by a further 2.

5C doubled is down 2, -500

As North would you bid 5C vulnerable as a sacrifice?
