gib escaping from 1nt double

[bb79]

[hv=d=n&n=sht8542d98642ck83&s=sat82haqdj53caq95]133|200|pass-(1♠)-1NT-(X)

2C*-(pass)-pass-(pass)

 

[/hv]

 

I overcalled 1NT,

gib alerts 2C as 2 suited 4+clubs

 

 

Seemed a little weird to me, although it made 2C :)

 

 

 

I also encountered a similar situation:

(1C)-1NT-(X)-2D*-p-p-X-ppp

 

*2D 2 suited 4+D

I was 4234 16 count, gib had 5242,

not sure what to do, thought second suit was hearts, i had -800 that time, maybe my bad.
