Last night at a local free poker event, a discussion broke out about legitimate raise amounts. I'll give you the example that I used to try to prove my point, and we'll see from the experts here who was right.

MTT - blinds are 30/60
Hand is dealt and UTG Raises to 200 preflop. Cutoff intends to reraise - what is the next minimum amount they may raise the bet to?

a) 260
b) 400
c) 340
d) 210
e) 230

Let's see who was right...
