Partner open 1♠ in 3rd position.
I respond 2♠ and partner jump to 4.
My hand : ♠109632 ♥Q754 ♦ 82 ♣ K7
Partner : ♠ AQJ74 ♥ --- ♦ AK53 ♣ AJ93
After the hand, partner said i was too conservative. Should bid 4 instead of 2.
I said that opps are 2 passed hands and p open in 3rd position. If he has a minimum opening hand
he will perhaps go down. The fact of bidding immediately 4 is like i was prempting partner.
What do u think of that ? ty
The responding hand potentially covers 4 losers, leaving out the possibility of the 10th trump covering a loser.
Single raise shows 3 potential covers, so is an underbid. Basically, it assumes the ♦ queen is useless.
Jumping to 4 assumes essentially that opener lacks the ♠ queen, so that the 10th trump is not a duplicated value.
Personally, I raise to 3.
