tough hand, i choice dbl,rebid NT,maybe have 3nt.

duck SA ,wait declarer make mistakes. if he guess right,4s is makeble.

I prefer "pass".sometimes it's very easy to bid,sometimes it's very difficult to bid. for example : pass pd 's double or redouble etc. I think if you bid "pass" ,you should be full of confidence. The most important reason : "pass" is the lastest auction of every boards LOL GL all

I prefer 1NT too,waiting pd 's rebid,if pd bid sth, i will push it to game

i think 2♠ should make pass will lose game if pd have unbalance hand and good hcps

2♦ or 1nt when pd bid 3♣, i will bid 3♥ show stoper or bid ♠ ask pd's stoper for 3nt

pass ,I think ♥ ♥
