it seemed to me like everybody wanted to play

Somehow i smelled burnt chocolate as I saw everybody being eager to call.

1) call/raise flop? Normally I'd say raise, but see above. I felt like 50:50 being behind AA KK 99 and someone having a flushdraw. The longer i think about it i'd say AA or KK would have been reraised preflop, but these are microtables... hard to tell right?

2) correct fold?

Party Poker
No Limit Holdem Ring game
Blinds: $0.05/$0.10
9 players


Pre-flop: (9 players) Hero is MP1 with
UTG calls, UTG+1 folds, Hero raises to $0.55, MP2 calls, MP3 folds, CO calls, Button folds, SB calls, BB folds, UTG calls.

Flop: ($2.85, 5 players)
SB bets $0.5, UTG raises to $1, Hero calls, MP2 folds, CO calls, SB calls.

Turn: ($6.85, 4 players)
SB bets $1, UTG raises all-in $7.6, Hero folds, 2 folds.
Uncalled bets: $7.6 returned to UTG.

Results:
Final pot: $7.85

The player afterwards said he had 44... i answered having fold AA suited, which is about as realistic as his 4s I guess
