Yes, A Spade lead is the only change to make. East will be squeezed.
- At my table I was sitting East and my partner did lead a Club. I did like that
- I was kibitzing at another table and there the lead was Heart T. First I thought that this would lead to the squeeze, but then realized: No squeeze because East has a not busy card.
- At the bar I was told that Spade was lead at another table. No real experts in my club. So East did throw a Heart instead of putting club K sec and give declarer a guess. (Good defence requires to see this soon enough. Too much thinking would give it away)
