I know that 1♠ 4♥ by partner is a splinter bid showing opening hand with 4+ spades and shortnest in Hearts.

What should 1♠ 3♥ mean if you are playing 2/1 with 1NT forcing?

Thank you

1S - 3H could be used as part of the Bergen Raise system with an unspecified stiff or void :

1S - 3H
3S ( next step asks )
.... ??
...... 4C/4D/4H = singleton
...... 3NT = void somewhere
4C ( asks )
....... 4D/4H = void
....... 4S = ♣ void

I would treat it the same way I play jumps to 3♣ and 3♦, whether that's weak jump shift, strong/Soloway jump shift, a Bergen structure as Two4 suggested, or whatever else you might be playing.

This consistency has the advantage of being easy to remember, in addition to whatever other benefits you expect.

A common treatment around here in the context of Bergen raises is for 1♠-3♥ to be a 3 card limit raise. Another option would be to allow 1♠-4♥ to be natural and have 3♥ as the splinter bid.

I currently play jump shifts in response to a major as a 6+ card suit with invitational values and no fit. This takes a lot of pressure off the 1NT response.

But yes, treating them in a similar way to your 3♣ and 3♦ responses makes a lot of sense for any but the most practiced partnerships.

I play Hardy raise,so 1♠ --- 3♥ ,it shows low limited raise, game force with 4 card ♠ support and also called concealed splinter with unspecific stiff or voidness in some suit.

If you don't want to use is for one of the artificial methods others have suggested, you could play it as an invitational hand with a six-card suit and no spade fit.

The choices are basically strong jump shift, invitational jump shift, weak jump shift (European-style WJS), preemptive jump shift (US-style WJS), or some kind of spade raise. I personally play it as a mixed raise in my favourite structure. There is no "must have" meaning here - you just choose something that seems to fit well with the rest of the system and is easy to remember.

Playing 2/1 there is something to be said for playing 3♥ as invitational jump shift.
