East has denied a 4 card major with he second round 2D bid. But West is looking for a 4 card major so presumably he has at least one. So you’re on lead. What do you do?
If you’re thinking about the auction then half the battle is won. Whether or not you find the best lead on this hand or not doesn’t really matter. Keep thinking, using the clues and in the long run you’ll do well.
