Ckeck-raise semi-bluff

[Cardsharp]

I was wondering if something like this could be a profitable move to use:

25nl 6max

cutoff raises to $1
button folds
small blind folds
hero calls with :Js: :Ts:

Flop comes: :Ac:
hero checks, cutoff bets $1.5, hero raises to $4.5

I never used this move but against some opponents it seems like it can be profitable. Especially because hes probably blindstealing.
This obviously depends on what kind of player you're up against. but lets say its a pretty good player who understands position and uses continuation bets.

lets say you raise to 4.5 and he re-raises you, what then?
lets say he calls and the turn brings a non spade card, what then?
And what if a spade does fall on the turn? what would be a good way to extract the most out of it?

And what about if you're in position, and he bets out on the flop? would this move still be viable?

I'm planning on using this move every once in a while. This way I think i can get more value out of my made hands too if i use the same line.

Why would you call or raise with this hand when facing a bet in the first place?
A blocking bet is an option. It depends on how strong you think his range is and the likelihood of him raising your bet on the turn.
How do you make money when you have a good hand anytime?

And what about if you're in position, and he bets out on the flop? would this move still be viable?

Yes, and allows the flexibility of a free card play if he calls.

Ding ding ding.
