Why does the robot bid 2 spades here?

Why bother showing spades here? I'm very rarely if ever going to want to play in spades.

Before you criticize my 2♣ bid, I would bid the same with ♠xx ♥KQJx ♦QJTxxx ♣x so it shouldn't affect the robot.

Out of interest, for what do you suggest 2S to be reserved to show? And what is your recommended auction on the cards held?

No idea for the first question.

Auction should be

( 1♠ ) - 1NT - ( P ) - 2♣

( X ) - 2♦ AP

2S is normal there, it helps break down the shape in order to decide the contract should South be interested in a possible minor suit contract.

after 1nt, the meanings of 2♣ you bid was stayman, not other.so GIB should answer 2S,no problem.

now for this hand,you should bid 3♣ to transfer to 3♦ with 6 card bad ♦ suit,then pass.this is just a normal bidding sequence.
