I would like to know, if I do (for example)

Code:

    push [esi+14]


Where is it actually going? If I wanted to "inc" it, what would I do?

From Intel's instruction set reference manual:
Quote:
PUSH — Push Word, Doubleword or Quadword onto the stack
...
Decrements the stack pointer and then stores the source operand on the top of the stack.

In other words, it subtracts 4 from esp and moves the specified value into the new [esp].

To increment the value on the top of the stack, use inc [esp].

Alright, esp is the stack. That's what I needed to know! Thank you!
