Trump Strip Squeeze


 by Richard Pavlicek

A trump strip squeeze (as used here) is a generic description for any strip squeeze in which the trump suit plays a significant role. Most notrump-feasible strip squeezes have a counterpart with ruffing involved. Note that each technique described here loses at least one trick, else it would be a trump squeeze.
