My first successful psych

[Quartic]

In 3rd seat against good opponents, I decide to psych 1♠ with a 2 count, and the bidding continues:

 

[hv=pc=n&e=st9632h8753d2cq73&d=w&v=0&b=8&a=pp1sd3s(pre-emptive)ppdp4dppp]133|200[/hv]

 

When dummy hits, I see I've created some real problems for South, who has a balanced 25 count.

 

The full hand was:

 

[hv=pc=n&s=saqhaqj2dak6caj84&w=skj87hk4dt974c952&n=s54ht96dqj853ckt6&e=st9632h8753d2cq73]399|300[/hv]

 

Declarer made 11 tricks, losing both major suit finesses, after I led my ♠3. Most of the field were in 3NT; one pair bid and made 6♦.

South has no err, marbles, and needs to bid 3N

South has lost his err, marbles, and needs to bid 3N

 

He believed my bid and thought his partner therefore probably had a yarborough and he'd have no entries to dummy.

My first succesful psyche was opening 1♣ in first on a two count and keeping a straight face when I realized I had counted my cards instead of my points.

If partner has a yarborough and not an extreme shape which the bidding and hand suggests then diamonds would be hopeless anyway might as well gamble on 3NT straight- an extreme hand with a long solid minor should be jumping to 3NT straight over the 1♠.

Quartic, the hand you put up looks similar to a hand that opened 1♣ against me - just switch the black suits. I had a hand similar to South, and luckily was playing with a really weak partner who played 3NT = 25-27, so I just bid it. Ended up making 6 when partner had (♦KJxxxx + ♠Kxx), and just lost the A♥.

 

Even without the agreement, South should just bid it. Either East is lying, or East has most of the points, in which case I bet we can endplay him/her. If we don't make it, that's just bad luck.

Agree that south should just bid 3NT at some point. However, is anyone else curious as to why North only bid 4D?
