My thinking process :
preflop : standard open MP
flop : c/f since there's no equity to continue, so I put it in my giving-up range.
turn : c/r got two way straight draw, I could bet to represent TT,99, but it wouldn't be logique to barrel the river. Vaillain's range is capped, once bet, most of his range would be draws. I would prefer ending the hand here. Maybe the raise sizing should be bigger.
river : c/r I hit my hand, which was well disguised. Since the flush card is a bad card for my range, I prefer checking to let him bluff all his missed draws. He made the flush, but results aside, since he checked back on the flop, should it still be +EV to raise the river ? I could be very wrong, so please give me your input on this.

Thanks,
Francis.
