0,25/0,5 AQs

It's kind of weird that you overplay your hands where you're supposed to play more passively and in spots where you were supposed to give more action (Q5:diamond: and AJ) you decided to settle down. You openraised Preflop and Mp's Donkbet shows a "lot" strenght from a passive player. It's ok to raise because he may donk A8 AT A7 and you gotta protect against all the draws but once you've shown the passive guy to have Ax+ he's certainly not 3betting with any worse hand. Respectively you're behind against his entire range so after he did bet => Calldown. Once the pot became that big i don't see the chance to get off the hand at any point. But if you're certain he's continously cautious with his action folding river is ok.
