would be nice to have the notation defined right away or in comment section

you have KsQh on button, check 5h8d10d flop and probe Jh turn. You say it's because you block hearts, what do you mean by this?

My take: Minimum 3.5x PF. You should probably tack on limp bets to the 3.5x PF bet raise, too. Check the turn and reevaluate on the river since you don't have the nuts and TJs is within lower-half of MP range. Were his cards suited? That would add a flush draw on the turn, too.

CO has a huge chip lead and position. 3-bet to 5bb is <10% of his stack. All of these factors allow for a wide range. I think it's perfectly fine to fold PF rather than risk ~1/10th of your stack - since he has pocket pairs and an ace in most of his range, though you could rep a high pocket pair and win if an A doesn't come on board. Betting 1/2 pot OTT indicates blocking the flush & the straight while holding a pair of aces. You can hit a Q, K, or J to win - 10 outs, but you're not getting pot odds. I would've folded PF, but folding OTT seems correct to me.
