V is a good capable reg, who I've played a lot with.

The game is playing 6/7 handed at this point. I have £3k, V has me covered.

V opens utg+1 to £35, it folds round to me in the BB, I 3b to £120 with QQ, V 4b's to £300, I call

(This was V's 2nd or 3rd 4b in this game alone, although I couldn't recall any of his 4b pots going to showdown. I had been 3betting somewhat actively)

Flop: 873r

I check, V bets £400, I call

Turn: 6c (brings flush draw)

I check, V bets £875, I call

River: 6x

I check, V shoves (for around £1.5k effective), I fold.

My thoughts afterwards are that I should have called off on the river, and I'm folding too much if I don't. I do however have a lot of low-mid suited connecters in my range here, and occasionally KK, so I'm not folding the top of my range by folding QQ.

Should I be really making my mind up on the turn here?

Flatting is obviously an option pre to save these spots, which I will do sometimes, but partly due to the game being shorter I decided to 3b this time.
