"For those who say a 2♣ rebid is “artificial”, then I would inquire how ever to show ♣'s, and just what the “artificial 2♣” shows or asks?"
2♣ for me shows a 4-3-5-1 with extras (i.e. 15-17 HCP) whereas 2♥ shows a minimum hand with 3 hearts ...
I think the spade ace lead was fatal for the defense on the first board. You still get your heart trick after the spade lead and continuation, which results in a trick in each suit for the defense. Promoting the ♠Q is necessary to set 3♠.
Playing in 7♠, declarer claims: "I'll ruff a heart and the dummy is high."
Considering that it would be quite safe and rational ...
Ruffing the 4th ♣ in dummy doesn't work when RHO has 2-3-4-4, because you block the spade suit. Also, if you decide to play for 4-1 diamonds, play a club to dummy and ride the ♦10, that way, you make an overtrick when clubs break and cater for Rosenberg ...
The ♦6 was important, because declarer would have gone down after a diamond to the king if he held the ♦5 instead. West would have exited with the ♦J after winning the ace, and maintained a tenace (♦8-6) over declarer's ♦7-5 in the endgame.
If the ♥J denies any higher honors and if declarer can be counted on to have exactly 4 hearts for his bidding, declarer must have something like ♠Ax ♥AKxx ♦KJxxx ♣xx. If his second spade is not the 10, a high spade return will set the contract, provided that partner ...
I can't see why cashing the club would be necessary, we can't be endplayed in hearts if declarer is 2-5-3-3, because declarer has only 7 tricks. On the other hand, cashing the club lets declarer make if he has ♠Ax ♥AQJxx ♦Jxxx ♣Qx. It could be argued that ...
In my opinion, there are three alternatives, which are: Pass, 3NT and 4♦. A case could be made for each of those:
i) Pass: Partner has at least invitational values, and he probably denied a huge diamond fit. If he has a doubleton spade, pass will get us a ...
