KT on KT5 board is a fantastic hand because AK/KQ are more than happy to pay you. The hands you have beat versus the hands that have you beat is just too highly in your favor, you must indeed pay off most players here.

The only situation where fold is something to consider is if a weak-tight nutstraddler reraises you. Weak-tights dont even reraise with AK, they only reraise with absolute monsters.
