Here was a hand from our KO final from the Fabulous Palm Springs sectional on Saturday. (yes that's what its called LOL).
Our teammates reached 3N on the NS cards after East opened 1♥ in 3rd. A heart was led and due to the lucky spade position, declarer was on pace to win 3+1+1+4. However, Victor Anikovich found the nice play of the ♠K on the first round of the suit. Try and make 9 tricks now.
At my table, my RHO checked out 1♥x'd. We lost 7 on this board and the match by 5.
