Contract 5 ♦
Lead: ♣ Queen.
After the board my partner was so happy about his ♣-lead, and that he didn't lead my suit ( ♥ ).
Furthermore he thought it was so brilliant that when he got tricks in spade, end-played declarer - so that I suddenly got 2 ♥ tricks.
I told him that there was absolutely nothing to be happy about - his lead, actually gave away the contract, but as declarer didn't un-blok his ♣ 10 - he was unable to finess my partner - and then discard a spade, on a high ♣.
That declarer - twice in dummies hand - not playing a ♥ towards the declaring hand, is his mistake not our braveness.
Am I right or totally wrong, when I say that the lead gave away the contract, if we had had a reasonable good declarer?
Thanks
