Lets start immediately about how I lost with my A-8.
It was a sit & go with 6 players.
Pre-flop: VILLAIN raises from early position, I three bet him with As8s from middle position. Others fold but VILLAIN calls.
Flop: 6c Ah Qs
VILLAIN checks, I check
VILLAIN bets, I three bet him and go all-in, he calls
VILLAIN has AdQc
