Don't think you can do anything here, p is still possible to have 6 clubs and, even if he has 5, there is no promise of a better fit you can run to.

Robson and Segal says it is possible for ♠AQ742 ♥63 ♦Q54 ♣J75 to pass and then jump to 3♠ after p's dbl after 1♥ (2♣) at vul IMPs So maybe it is also the case for a 2-5-3-3 or 5♥-4♦ 9-10 count here

If you don't want opponents to balance over your transfers, you might just try something like 1NT 2♦=weak with ♥ or inv+ with ♠ 1NT 2♥=weak with ♠ or inv+ with ♥ Which makes direct actions dangerous for 4th hand B-) and good for rightsiding.

May play in a 4-2 fit heart contract And dunno what to do if p comes up with 3♥

[hv=pc=n&s=saq742ha6dk7ckt52&d=s&v=e&b=3&a=1s2dpp]133|200[/hv] With doubleton in their suit, passing looks dangerous, but there's no convenient call I can make:(

Just for something fancy :D 1♥- ……1♠=weak with 0-4♠/invite with 4-5♠/GF relay …………1NT=bal or 4+♦ ………………2♣=force 2♦, SO or any inv ………………2♦=GF relay ……………………2♥=bal ……………………2♠+=5+♥-4+♦,step +0 ………………2♥=SO …………2♣=4+♣ ………………2♦=inv+ relay ………………2♥=SO ………………2♠=nat inv …………2♦=4+♠ ………………2♥/2♠=SO ………………2NT=GF relay, step +1 …………2♥=6+♥ ……1NT=weak with 5+♠ …………2♠=can be doubleton …………else=nat ……2♣=♦ NFB, or invite with 0-3 or 6+♠ …………2♦=nothing special ………………Pass=♦ NFB ………………else=nat inv …………else=nat max, promising 3♦ ……2♦=good ♥ raise ……2♥=bad ♥ raise ……2♠=weak 6+♠

How often will p rebid 1NT on 5m4m22?

From the eyes of people who live on earth 20,000 years ago, poverty is already history :(

In a relatively weak field I think it is better to leave pass as to play :unsure: So it's something like P=to play, opener can pull with a 5 card suit XX=relay to 2♣, 1-suited, or some GF freak hands 2♣/♦/♥=2-suited, with a high ranking suit 2♠=1-suited

I'll suggest 1♥-1♠-2♣ -2♦ forces 2♥ for sign off or invite -2♥ GI -2♠ GF relay Relays are at +1 but having 2♥ as GI is more important.

Seems that you have problems with 1)Responder is max for a 1NT response, opener has 12-13 balanced and passes you out. 2)Opener has a max and responder has a misfit 10-11, e.g. 1534 over 1S-1NT-2D.

1♣(15+nat/bal,21+any)-1♦(0-5 or 13+ or GF bal) 1NT(20-22bal)-2♣(stayman) 2♥-4♥

P-1♣(15+nat/bal,21+any) 1♠(semipositive bal or ♦)-2♣(GF relay) 2♦(bal without 4♠)-2♥ 2♠(4♥)-4♥

1♦-(2♥)-X 3♥-4♦ 4♥(RKC)-4♠(1/4) 6♦ Seems not possible to check ♠K.

1♣(15+nat/bal, 21+any)-(X)-1♥(semipositive 4+♠) 1NT(15-17bal)-P

Tough hand for me 1♦(3+♦ unbal 11-21)-1♥ 3♣(5-5 invite)-4♦(nat slam try) 4♥(RKC)-4NT(0/3) 5♣(ask ♦Q)-5♥(♦Q+♥K) 6♦

1♥（standard)-1♠(various,F1,nothing about spades) 1NT(4+♦ or 15+)-2♦(nat weak) 3♠(6+♥-5+♠ GF)-4♥

But you'll really get hurt when you have ♣ and p want to be the declarer of 3NT :(

Is it possible to play… 2♥=15-17 3♥ 2♠=18+ 5+♠ 2NT=4♠ & a 5 card minor 3♣=6+♣ 15-17 3♦=3+♦ 15-17 though there is still trouble with the 2NT rebid.

P-1♣(15+nat/bal, 21+any) 1♥(4+♠ 6-12)-1♠(relay) 2♣(♠&♦)-2♦ 2NT(5+♠-4♦ short ♥)-3♣ 3♦(5143)-3♠(RKC for ♠) 3NT(1/4)-6♠

1♣(15+nat/bal, 21+any)-1♥(4+♠ 6-12) 1♠(relay)-2♣(♠&♦) 2♦-2♥(4♠-5+♦) 2♠-2NT(short heart) 3♦(ask ♦ honour)-3NT(0 of top 3) 4♠

1♣(15+nat/bal, 21+any)-1♥(4+♠ 6-12)-(2♦) 3♠(4+♠ GF)-4♠ 4NT(RKC)-5♣(1/4) 6♠

1♥(standard)-2♣(either 6-9 6+♦ or some invite) 2NT(bal or 4♠, 16+)-3NT Don't think east will interfere here.

P-1♣(15+nat/bal or 21+any) 1♦(0-5 or 10+)-2♠(6+♦ 21+) 3♦(signoff)
