on three cards? Just curious

Well, from time to time it is a good choice. More often, there is a preferable alternative.

Honestly I don't see this all that much, not nearly as often as rebidding a 5 card suit for no reason.

Because it's recommended expert practice in the U.S. and has been for decades, holding a min opener and a stiff outside, and sometimes also on small doubletons depending on style. As opposed to unheard of in France. And presumably other parts of Europe, Portugal also I suppose from your location?

Sometimes partner has 5+, it works out fine, auction can be less revealing to opponents. Sometimes partner has 4, it allows partner to declare NT from his side instead of yours and it makes from his side but not yours. Raising can work out better playing a 5-3 or 4-3 fit rather than rebidding a 5 bagger and playing a 5-1 minor fit. Sometimes playing 4-3 2M scores better than 1nt, with the ruff taken in the short hand. Sometimes the opponents balance you out of your 4-3 fit to your benefit.

And sometimes partner has 4, you play 4-3 fit, and you'd rather have been in 1nt. Oh well. And sometimes when partner has 5, not knowing 9 cd fit for certain can affect borderline game & slam decisions.

And if you raise on 3 on the right type of hand, and you wind up playing in a 4-3 fit, often it plays very well.

Why do people on BBO insist on...

jumping to game with only four cards in their suit after I've made

a simple raise? Just curious

It's not unheard of in Portugal. In fact, I was the first to play it LOL. Thing is, the only follow-up people are widely likely to know is "treat it as 4-card support anyway", so this is what I do as well. Sometimes dummy does not live up to expectations

See above. I'll be aware that some people play "support non-doubles" without warning.

I do this occasionally, but only on a very specific type of hand: 5 in my opened suit, 3 card support, 4 in a suit that was skipped over, and a minimum opener.
I don't like it, per say, I just like it better than the alternatives (rebidding the 5 card suit, reversing without the values to do so, or bidding NT with a stiff). The rationale is actually a bit like opening a 3 card minor suit: it makes it a bit more difficult if the opponents compete over your possibly-3-card bid, but it is much easier when you opened with anything else since other bids are better defined than if you required 4 cards.

Of course support doubles would be better, but that pesky Law 36 gets in the way.

[beatrix45]

In North America it is acceptable to raise on three once in a while. The caveat is that it be the right sort of hand, and that no other bid is as descriptive. The right sort of hand is not that common. You need to have a ruffing value. You have to be able to play opposite Jxxx (sorry if you responded on 8xxx). Trump support of Q10x is pretty much a minimum. Cowboy up and learn to play the occasional 4-3 fit. Opponents will learn not to balance so recklessly when they are unsure if you have seven trumps or nine.

There are 2 schools

1) Raise on three, rebid 1NT when the hand is in range even with a singleton spade but looks otherwise looks suitable for notrumps (half stoppers in unbid suits). Responder rebids his major over 1NT only with six or very good 5 cards.
2) Raise on four, never rebid 1NT with a singleton spade, but otherwise rebid 1 notrump whenever balanced and in range. Responder rebids his major over a 1NT rebid frequently with 5 cards.

Obviously 2 from different schools do not make a good partnership.

The first usually does a better job in choosing the right part-score
The second one has a slight edge in game and slam bidding.
