Here's a memorable hand from Just Play Bridge on bridgebase.com I'm south (playing with bots). [hv=pc=n&s=s2hakq82dkq95cak8&w=skt83hj97543dcj95&n=sj96hdat8643ct763&e=saq754ht6dj72cq42&d=n&v=n&b=5&a=pp1hp1np3dp3hp4hppp&p=c5c3cqckhah7c6h6hkh4s6hthqh5s9s4dkh3d3d2hjc7c4h2h9sjd7h8cjctc2cadqstd4djd9s3d6s7d5s8d8sqdas5s2c9dtsac8]399|300[/hv] North's 3♥ should have promised 2. I couldn't bid 4♣ because it would show 0544 shape. I opted for a safe game in hearts with a 7-fit rather than rebidding ♦ without extra length or the ace. North didn't even correct to 5♦. Running 3 trump reveals the 6-2 split. West ruffs a diamond and drives out the rest of the trump. Defense can run spades, but West instead returns a ♣, handing me the contract.
