Looking at the auction in isolation this is surely a penalty double. However what puzzles me is my !SA. How can LHO have a sensible four card overcall and partner have a penalty pass of 1!S? Surely partner would have bid 1NT with 4 or 5 mediocre spades? I guess LHO may have psyched?

Isn't it West to lead having overcalled 2H?

[hv=d=n&v=n&s=sak732h7dk5cat983]133|100|Scoring: IMP[/hv] P 1♥* 3♣** P 3♦ P ? *1♥ is part of a precision system, so limited opening and could be canape. ** 3♣ shows the black suits. You haven't discussed range at this vulnerability. Two questions: 1) What does 3♦ show? 2) What's your rebid? This may depend on your preempt style first in at unfavourable. Your preempts are middle of the road, so not particularly agreessive nor extremely sound.
