IMO, systemically, after 1N - 2♣ - 2♥ - ??,
  • 2♠ = INV 4♠
  • 2N = INV No 4 M.

but perhaps GiB decided that ♠ J T x x wasn't worth emphasizing :)

I wouldn't be surprised or unhappy if a human partner did the same, given also the diamonds and the low probability of a spades fit when partner has already shown hearts.

I don't think gib can't count to four. It has something to do with the hand having 7 points and being unbalanced I think.

Change ♦Q to ♦K and GIB will bid 2♠. So it's nothing special like the quality of the clubs; seemingly just a glitch in the rules, precisely when GIB has 7 HCP and 10 TP it looks like.
