Hey guys

I just need your guys opinion on this hand that I recently played on 50nl FR Zoom. I currently use a mac book pro so in-game i couldnt get any stats on villain since PT4 isnt compatible with Zoom on a mac.
PokerStars - $0.50 NL FAST - Holdem - 9 players
Hand converted by PokerTracker 4: http://www.pokertracker.com

Villain stats: UTG+1: $55.97 (VPIP: 37.50, PFR: 25.00, 3Bet Preflop: 25.00, Hands: 8)

Hero (MP+1): $94.86

SB posts SB $0.25, BB posts BB $0.50

Pre Flop: (pot: $0.75) Hero has Kd Kc

UTG raises to $1.25, UTG+1 raises to $4.50, fold, Hero calls $4.50,

Flop : ($11.00, 2 players) 9s Qs 7s
UTG+1 bets $10.50

Looking back on it now, based on just 8 hands villain's stats are super aggro...is this a clear fold after villain pots flop since we don't have a spade? Villain immediately 3bets utg raise (14/11/7), so obviously he could potentially have QQ maybe even AA or AK(with a spade)?...I decided to slow play and not 4bet pre since both of us started quite deep with over 100bb and to disguise the strength of our hand...
