MP2: $5.05 (101 bb)
Hero (MP3): $5.02 (100.4 bb)
CO: $8.82 (176.4 bb)

Preflop: Hero is MP3 with K K
UTG+1 raises to $0.15, 3 folds, Hero raises to $0.45, 3 folds, BB calls $0.40, UTG+1 raises to $1.82, Hero ?????????

I think, above, villain has AA pretty much 80% of the time since UTG raising has a lot of strength. I was hoping QQ or another KK so bad lol. But surely next time in this position I should be folding against villain's 3bet ranges which are similar to his? Or is folding KK here a bit nitty?

As played though I got lucky: calls $1.37, BB folds

Flop: ($4.11) 4 K 8 (2 players)
UTG+1 bets $1.37, Hero raises to $3.20, UTG+1 calls $1.83

Turn: ($10.51) T (2 players)
