-110 was a poor score even in a bad club game.
ATB?
East: 80%
West: 0%
The universe: 20%
East should bid (at least) 3♠ over 3♦; 4♠ wouldn't be out of line.
Both sides have undisclosed double fits, so LOTT doesn't apply (without adjustments that the players cannot know are necessary); that's the universe's 20%.
