Andrew’s favourite conventions (four)

With a fit for partner and a weak hand, preemption is of primary importance. With a stronger hand, the partnership need to conserve space in order to explore all possibilities. Hence “Inverted Minor Suit Raises” are an essential convention – the fourth in my series.

When partner opens 1 ♣ or 1  and the next hand passes, a 2 ♣/2  response shows a good hand – at least 10 points – and the  3 ♣/3  response shows a weaker hand – 6-9 points. Whilst the 3 ♣/3  response makes life more difficult for the opponents,
the 2 ♣/2  response – forcing partner to speak again – allows more room for partnership communication.

If North-South had not been playing Inverted Minor raises, North would have responded 3  to 1  and South would have potted 3 NT – defeated by a deluge of ♠s. But over North’s 2  inverted raise and South’s rebid of 2 NT to show his balanced hand, North and South had room to bid where their values lay, and so exposed the ♠ weakness.

West led ♠ K against 5 , and switched to  2 to  K and  A, Declarer drew trumps in three rounds, cashed four rounds of ♣s discarding  7, conceded a trick and cross-trumped the last three tricks.
