Just one further question - what if responder is 4333? The usual guideline is:
If the holding is 4-3-3-3, most partnerships treat the holding as two-suited.
Not sure what that means but I am guessing that if the 4 card suit is a major then you start with your better 3 card minor?
Often I just pass. If my 4-card suit is poor, or I have enough points 1NTx might make on a good day, or I have the feeling that my LHO is going to take the double out anyway.
If I feel that pass is likely to end the auction and it will be a bad result, then I usually bid my 4-card suit unless it is spades in which case I bid 2♣. But it is possible that bidding the better minor with 3433 or 4333 is better. The quality of the 3-card suit doesn't matter so much technically, but the more strength you have in your suit the less likely you are to get doubled.
With a good 4-card suit and three small trippletons I treat my suit as a 5-card suit.
One reason to escape even if you don't believe it will lead to a better contract it that opps might not double you in a suit contract.
