Trump Squeeze

by Richard Pavlicek

A trump squeeze (as used here) is a generic description for any squeeze in which the trump suit plays a significant role. In fact almost every notrump-feasible squeeze has a counterpart with ruffing involved. Note that techniques described here win all the remaining tricks, else they would be a trump strip squeeze, covered in the final category.
