at 22:00 hero cbet 1/3 pot on K77 board with a643 and gave up on turn and river when flush draw got there and let villain's K623 get to showdown as the winner. i think it's worth discussing strategy and bet sizing (for double or triple barreling concerns) on those paired board spots especially while having the initiative.
this seems to be my biggest leak in PLO cash games as well. i sometimes freeze up as the aggressor on paired boards (similar to this scenario) bc of my lack of bet sizing knowledge. i want to represent trips or better as best to my ability.
my guess on optimal bet sizing in these spots would be e.g. i bet 1/3 to 1/2 pot on the flop, then perhaps 75-85% pot on the turn and 75%-85% pot on the river -- perhaps this sizing on a triple barrel would force opponents to incorrectly fold medium strength hands; and on the other hand, pay off my stronger hands when they decide to be stubborn.
*if i end up getting a live read (or an online timing tell) that my opponent has trips or better then i would shut down on the turn or river
interested to hear anyone's input on the matter. cheers

You shouldve flatted the flop with middle set but I understand why you raised vs the LAGs that play every hand

Flatting the flop with middle or bottom set with SPR 8+ helps overall strategy of having stronger range on later streets and you wont lose your stack vs top set if board gets scarier
