Looks fine against an unknown reg, turn call is fine as I expect them to bet their bluffs, don't think too many 5nl regs are bluffing the river though.

Looks ok to me. Something to note is that on the ace high board a 3 barrel is very very rarely anything else except for value at these lower stakes.

Always a shame to fold the ladies, but nice disciplined play imo.

Reasonable line. Value-bet turn for a small sizing is typically the best. Can even often underbet river again for value.

Looks good to me.

As we expect most villains to bet their Ax combos once we check value betting the turn for about 30c is probably better than checking though. The same applies on the river; with a very small sizing we don't expect to get bluff raised by any showdown value hands, but they're going to be more likely to call you down.
