Open 1H, partner responds 1S, you rebid 2D. Partner raises you to 4H. All Pass
Acol Bidding
Open 1H, partner responds 1S, you rebid 2D (partner now knows you have a 5 card heart suit). Partner raises you to 4H. All Pass
Plan Before You Play
Dummy goes down, in a suit count your losing tricks. Spades:0, Hearts:1, Diamonds:0, Clubs:0. To make 13 tricks plan to not draw any rounds of trumps just over-ruff if the opponents trump in.
The Play
Win the club lead. Diamonds and Spades are the suits you will cross ruff. Lead JD to cover with AD, ruff a low diamond, play AS and then ruff a small spade, ruff a small diamond and play your KC, QC and over-ruff Easts ruff of the 9C. Hold your nerve and ruff the last diamond. Ruff a small spade and now play your last 2 trump cards. Making 13 tricks
Comment
Can you make 7H? If you count the outstanding trump cards only the QH is higher than your top 6 trump cards. If you just cross ruff all of your side suits planning to over-ruff if the opposition ruffs, then you can make 13 tricks!
