It is against weak reg, we have not special dynamics betwen us, no stats, it is Partypoker
preflop - mixed 3bets or calls
flop - I can cbet 1/3, x/c is also fine
turn - nothing,
river - his range is quite capped, his hand is medium strenght type one pair 90% of time I think, something like Kx, AQ, AJ, JTs, J9s. I also can have some show down value against some 1 barell bluff give ups like 65s, 97s or A5s for example, but it is qute small part od his range. So I think that, it is a good oportunity for bluff and I also like my sizing, at least I still have KK, JJ, QJs.

So it is my bluff okay, or it is too ambicious?

Thanks :)
