After a single raise of major suit, is opener's jump rebid in another suit splinter?
If that's splinter, how do you bid a hand with slam interest and good 2nd suit? I dont like such sequence: 1M-2M-3m-xx-4m.

Why do you not like such a sequence? You can't have it all.

splinter is the most important tool forward going to slam, giving it up is plain wrong.

I'm not sure I follow the problem.

Suppose a specific auction start:

1♠-P-2♠-P-
3♣

I'm assuming, of course, that 3♣ is a natural GT, possibly a slam try.

Responder, if accepting the game try, need not simply blast game. There are other options for strong Responders.

1. 3-level calls below 3♠ are reciprocal game tries OR anticipatory cues.
2. Responder can cue 3NT, a "super-acceptance" of the new suit (high cover count for 2♠, 4-card support for the second suit). This allows Opener to show the slam interest and refocus the slam strain with a 4♣ call, asking for the precise cover count; four of the agreed major showing bare super-acceptance, bidding the slam with maximum internal covers, bidding a side cue with maximum covers if this King is a cover.
3. Responder can raise the new suit with five-card support an great covers.
4. Responder can eventually cue at the four-level and add in Last Train, possibly.
5. Opener can bid Last Train and Serious 3NT.

If Responder shows a weak hand (declines), Opener still can cue, show serious interest (3NT), or use Last Train, as needed.

If Responder bids 3♦, Opener can actually make a delayed heart splinter, offering nuance differences from a straight 4♥ splinter (the former suggesting a diamond control, as the latter "needs" one).

What? You don't play that?

I play that opener:
- asks with 2NT.
- bid 4m is a void.
- bid 3x is 5-5, looking for low point game or slem interest

Depends on what kind of trial bids you
play.

If you play short suit trial bids, 4m would
show either void (fairly low frequence) or a
real suit (which would be my preference),
because 3m would show shortage.

I play long suit, so the jump is per default a
splinter, which keeps the memory laod at a
minimum.

With kind regards

This depends on what game tries structure you adopt.
I prefer a jump in a new suit to show a big 2-suiter looking for slam. Many play it as a splinter; some that it shows a void, some allow a singleton.
