Thanks for these, Jolan, challenging and enjoyable in equal measure as always.
Very glad to hear that today went well.
Here is my stab at the clues-
1 Throw off control and stop conspicuous cheaters playing (4,4,3,6)- KICK OVER THE TRACES?
Stop- kick, conspicuous – overt + cheaters anagram – kick over the traces- to throw off control?
2. Sister to cruel British male poet. She’s one too! (8)- ROSSETTI?
Anagram of “Sister to” gives Rossetti – Christina and her brother Dante Gabriel Rossetti were poets?
3. Type of salt added from the outside (2,5)- AB EXTRA?
AB – type of sailor – salt, and added- extra- ab extra- from the outside?
4. Too controlled to be an unsuccessful person (4-3)- ALSO RAN?
Too – also + controlled – ran- also ran – unsuccessful person?
5. Repressive sea captain takes no further action? (4,2,3,5)- SITS ON HIS/HER HANDS – What a repressive sea captain (of either gender, both fit) would do gives an expression meaning take no action?
Thanks again, Jolan.
Keep well.
