Some "easy" stuff here for you tournament players. Both of these are somewhat similar situations. I'll see what the answers are then give my 2 cents.
1. You're playing in a $100+10 buy in tournament live or online with around 100 players. First hand, it's 9 handed, blinds are 10/20, you have 2000 chips and you're in the cutoff seat. UTG (under the gun) limps in, followed by two other limpers, it's your turn and you look at QQ. You raise to 100. Everyone folds around to UTG who shoves all in. Limpers fold. You've never seen the UTG player in your life. No tells at all. What do you do?
2. First hand in a 9 handed sit & go. $11 buy in. Start off with 1500 chips. 10/20 blinds and you're on the button. MP player raises to 60, you look at AKs (suited), you 3 bet (re-raise) to 180. MP Player jams and you call. MP proudly flips over TT vs. your AK. Was it a good or bad play by either player?
