After the opposition open 1 Heart you overcall your spade suit. If you Count your Winners you see that you have 9 winning tricks in your hand so you can afford to safely bid right up to the 3 level even if your partner has nothing in support for you.
Acol Bidding
After the opposition open 1 Heart you overcall your spade suit. If you Count your Winners you see that you have 9 winning tricks in your hand so you can afford to safely bid right up to the 3 level even if your partner has nothing in support for you.
Plan Before You Play
Hand Evaluation: You are in a suit so count your winners . You can see 8 Spade tricks and the Ace of Clubs, so 9 winners.
The Play
After the Heart opening lead and another round of hearts, the opposition will change to either Diamonds or Clubs, you will lose 1 Diamond round and after that every trick is yours if you draw all the trumps, being careful to discard all your diamonds, then the Ace and King of Clubs for 10 tricks.
Comment
This hand can be overcalled and will make 4 Spades even though the opposition have a very makeable 2 Heart contract. It all depends who has faith in their own hand and keeps the bidding going.
The above commentary is intended as a guideline only. As with any Bridge hand there are many ways to bid and play any hand.
