Air bluff at a wet dry pot

I know I know spare me the "what are u doing in with 63" talk✌ it's a $10 freeroll that I'm just messing around with a few things. But some would never think of bluffing at this (actually wet) "dry pot" with the side pot being juicy enough to justify bluffing eith air when checked to on the river!

It would have been a great hand if it happened between two actual poker players, but on a $10 freeroll is just another example of beginner play. Hey, it's all good mate, I am in the same category as you are.
