Hi,
Try not to spoil the result in the title next time
Hard to say without having played with him, if you think he plays worse Kx and flushdraws that way but will fold Kx to a 3bet then calling the flop raise is fine, but you can't fold on a blank turn after that ever.
Personally, unless i had seen him make such huge bets with TPGK and/or draws before, his 1.4 AF would probably have scared me away, resulting in a "whatever, take it" fold.
Hope it helps.
