2♥. By bidding 1♠ all you get is a possibly better partial in spades. Pulling 1N to 2♥ shows about an ace more than this.
By bidding 2
♥ all you get is a possibly better partial in hearts, no? Maybe you'd have a better argument with a 13 count, but with a 10 count it's not like partner will invite game on hands with 5 hearts where game would be good if he knew we had 3.
Btw bidding 1
♠ does two other things. We get to a possibly better partial in notrump or we get to a possibly better partial in diamonds. Maybe I'd choose 2
♥ if I could but 1NT or 2
♦ can still be right.
Two other unlikely scenarios in favor of 1
♠: Partner passes 1
♠ and we stay lower, or partner rebids 2
♥ anyway which we are happy to pass on our subminimum when he would have bid more had we raised directly.
Please let me know about any questions or interest or bug reports about GIB.
