First hand:Good raises on first three streets.On the river,you're probably beat both ways unless they both have a straight & no decent low(unlikely).I would not fold here,either,even though it may be right.Maybe it would be a good idea to raise the river in case CO started with A24 or A25,& you can get him to lay it down.
2nd hand:I only would have called the turn,figuring MP had the flush & hoping to get a call from A5 in the BB.But your raise may have worked out well.Good river bet.
