David Parsons's bidding problem: J8 K542 QT7 8743
I tried to create an auction in which you might raise to four on a three card suit. By the comments here, some might never raise to four on a three card suit? What if diamonds and hearts were reversed...would you then consider raising to four clubs? Thanks.

2D is semi-automatic. Any other bid than 2D shows a five+ card suit headed by two of the top three honors.

David Libchaber's bidding problem: JT42 QJ AQ5 AK42
Your example hand, Chris, sets 5H by two if 5S makes five. At matchpoints, it's an example of my point -- 5Hx is superior to 5S even when partner is void of hearts.
David Parsons's bidding problem: Q AJ5 AK6 AK9542
I just ran a DD simulation on this hand. The results are that without knowledge of whether partner has three or four clubs (and based on the likelihood of each given what partner has told me) the grand slam will make 58% of the time, and the small slam will ...
