Ace high baby

Hands like the one showed below always feel nice, but especially when it's the very first hand at the table. So I didn't know the player and could only use my pattern mapper and timing tells (instant pot bet the river for example).
Offcourse this board texture is probably the best possible to make a call like this and as I have the Ace of hearts its very unlikely he has a bigger ace.
