The first hand demonstrates how running top clubs and then six diamond winners force opponents into a constrained spade/heart position, producing a twelfth trick via an enforced return. The second hand adds planning before a spade double finesse: cashing diamond winners to eliminate threats, using inferences about opponents’ spade/heart holdings from discards, and executing an end position to win by strip-squeeze pressure.","Strip squeeze  \nNow that it’s summer, let’s take a look at the strip squeeze. You are playing six notrumps after West opened one spade.  \nWest deals, North-South vulnerable  \n]T653  \n[Q3  \n}KQ  \n{AQ873  \n]KQJ982  \n[KJ4  \n}95 {J6  \n]A74  \n[A7  \n}AJT432 {K5  \n] [T98652 }876 {T942  \n\n| West | North | East | South |\n| --- | --- | --- | --- |\n| 1] | 2{ | pass | 3} |\n| pass | 3] | pass | 6NT |\n| pass | pass | pass |  |\n\nWest leads the king of spades, East pitches a heart and you win the ace of spades. You make a note that West started with six spades and run your three top clubs, pitching a spade from hand. All would be easy if the clubs divided 3-3 but East has clubs stopped. Next you play your six diamond winners, reducing everyone to three cards. West must keep H KJ so he only has room for one winning spade. (You verify that by keeping count of West’s spades.) West has been strip squeezed. You put him on lead with his spade and the enforced heart return gives you your twelfth trick.  \nOn the next deal you are again in six notrumps from the South seat, this time with no opposition bidding.  \nWest deals, neither side vulnerable  \n]AKT7 [76 }AQ4 {QJ52  \n]64 [T83  \n}J9632  \n{974  \n]98 [AQ42 }KT75 {AK3  \n]QJ532 [KJ95 }8 {T86  \nWest leads a low heart to the king and ace. You now have eleven top tricks and the extra one could come from spades or diamonds.  \nYou can play the hand for yourself in Bridge Solver here.  \nBefore you try the double finesse in spades, you play the ace and queen of diamonds, dashing any hope for a fourth diamond trick when East discards a spade. Furthermore, the spade discard makes it highly likely that East started with five spades, quite possibly headed by the queen and jack. You run your club winners. East follows three times then pitches a heart. You now know that East started with nine cards in the majors and from the discards you expect that to be five spades and four hearts. These cards remain:  \n]AKT7 [7 }4 {   \n]64 [T8  \n}J9  \n{   \n]98 [Q4 }KT {   \n]QJ53 [J9} {   \nWhen you play a diamond to the king, East is strip squeezed. If he discards a heart you cash the queen of hearts and run a spade to him, forcing him to return a spade back into the SAK10. If he discards a spade you run a spade around to East without cashing the queen of hearts. You win the heart return with the queen and dummy’s spades are good.  \nThis deal comes from the 2004 PABF congress in Taipei, reported by Teng-Yuan Liang.","cbCaihVWkisSE1Jy","https://ap.wps.com/l/cbCaihVWkisSE1Jy","pdf",118002,1,2,"English","en",105,"# Strip squeeze in six notrumps\n## Hand 1: forced spade/heart position\n## Hand 2: planning before double finesse\n## Source and context","[{\"question\":\"What is the key idea behind the strip squeeze shown in these hands?\",\"answer\":\"It pressures the opponent into giving up a winning trick by forcing specific spade or heart returns after reducing the opponent to too few cards.\"},{\"question\":\"How does the first hand convert the squeeze into a twelfth trick?\",\"answer\":\"After running top clubs and then the diamond winners, West is left with only room for one winning spade while an enforced heart return gives you the extra trick.\"},{\"question\":\"Why does the second hand cash ace and queen of diamonds before attempting the spade double finesse?\",\"answer\":\"It prevents East from developing a fourth diamond trick by removing diamond entry chances, and the resulting spade discard supports the inference that East started with about five spades and four hearts.\"},{\"question\":\"Where does the second deal come from?\",\"answer\":\"It comes from the 2004 PABF congress in Taipei, reported by Teng-Yuan Liang.\"}]","Strip Squeeze -
