SH NL10 facing donkbets

hand 1
You can just call Ace high. Ace high's relative hand strength goes up on paired boards. And I would call on many blank turn cards, especially low ones. Given you have Ad you can also call on flush completing cards and perhaps bluff raise to rep the flush if he does continue leading weakly.

I may call a 2nd bet more liberally especially if sizing is small. I want to get to showdown and get some reads, Ace high also has decent showdown value.

hand 2
I think it is quite similar to hand 1. Board may have some gutshots now but turn paired the board so your Ace high goes up in relative hand strength (as compared to some coordinating card like 9/T). I would call Turn and think about calling some blank Rivers. Of course we may very well get owned by 2nd pair but he gives us great odds. Important thing is to get to showdown and get some reads.

On the first hand, with showdown value and backdoor flush I would just call the flop and play from there.

On the second hand you can call again but also can raise to put pressure on his 1p hands (that are not TP). Unlike hand one he can have/fold hands like 8x or 66, 77.

However calling is fine. On the blank turn I would also fold. If it came down a T+ we can raise for semibluff or value depending on the card.
