5/10 - Hands in Pesos Are Confusing to Remember

[Slider]

I actually remember the stack sizes for this hand. This was live tonight at the APPT but I'm going to quote the stack sizes in pesos.

I'm pretty new to the table - played about 1 orbit. By far the youngest person there (so I automatically I assume I'm the best and that they're all really terrible - which was true).

I had opened the last 2 pots on the button and CO and taken them down with flop bets and I get weird looks when I raise this 3rd hand in a row.

Effective Stacks are 50k Pesos
Blinds 200/400

I open to 1500 with K[img]/images/graemlins/spade.gif[/img] Q[img]/images/graemlins/spade.gif[/img]

Button calls.

Flop: Q[img]/images/graemlins/club.gif[/img] 9[img]/images/graemlins/spade.gif[/img] 7[img]/images/graemlins/spade.gif[/img]

He checks - I fire 2700 into a 3400 and he calls without much thought.

Thoughts if:

A) I bet 7500 into the 8900 and he raises to 20k
B) I check and he bets 3000 into the 8900
C) I check and he bets 3000 into the 8900, I checkraise to 12k and he makes it 30k?
