Bridge & other card games/Renege tricks make game?
The bid is 3 diamonds, opponents reneged resulting in a 2 trick penalty. Bidder made his 3 diamonds, but with the 2 trick penalty, it gives them 5 tricks. Can they declare that as a game?
The answer to your question is no, they cannot receive credit for a game.
If a revoke occurs, that does not alter the original bid contract arrived at during the auction. The contract remains 3D, the revoke penalty simply gives them 2 overtricks.
