Responder's support bids of a major at the 3 level
The major difficulty of a 3 level support bid is determining:
  • if they are forcing and with slam hopes
  • if Game invitational
  • of even if they are pre-empts and need to stop at the 3 level
Two major rules of support bids are :
  • Rule 1 : after a 2/1 suit shift all support bids at the 3 level indicate Slam possibility and are 100% forcing
  • Rule 2 : after Responder's 1 bid, all support bids at the 3 level are forcing and are much stronger than a 4 jump bid

Problem 20154 3 , support bid at the 3 level (no jump) of Opener's 2nd suit is also a possible Slam bid.
 
 
After Responder's 1 bid on a 1 opening all support bids at the 3 level are forcing and are much stronger than a 4 jump bid
This rule applies on Opener's 1NT, 2 or 2 rebids. If Opener repeats his ... this is an exception! (there are always exceptions to the rules)
Only exception to Rule 2 : If Opener rebids his hearts after Responder's 1 bid, a support bid at the 3 level is Game proposal but very often with only a 2 card fit
