Two hands.. all cooler?

NL100 live 9 players

Hand 1,

Hero (120BB) early position raise to 6$ with 99. few players called

Flop A 7 3 rainbow.

Hero cbet 12$. only one guy (somehow tight, 100BB) call and says "You don't have Ace..." I said "Do i need to..."

Turn 9, Hero bet 20$, tight guy instantly all in. Hero instantly call.

River A

tight guy flip over AA ...


Hand 2,

Hero under the gun (80BB) raise to 6$ with QcQd two players call.

Flop 8c9cTh

Small Blind (LAG) check, hero bet 15$, young guy (also LAG)  call 15$, SB shove for 90$

Hero ?

Select to show:

Hero called. Young guy tank and fold 77 face up.  SB shows JTo, turn blank ,river Q, SB win with a str8,

第二手和我最近的一手很像啊，
那手我JJ CO, open 5BB， SB和一个MP call。
flop 789r，SB donk 3/4 pot，MP call， 我feel到我大概率落后了，just call for a surprising turn card.
turn 2，SB check，MP shove over pot, I fold, SB call，
open， MP 78, SB 99

第一手冤家牌，输了也就认了，第二手倾向于弃牌

第一手牌谁都仍不掉吧 比较难以理解的是tight guy为什么要在turn上allin 我比较喜欢在turn上call，等待hero来check-raise
第2手牌很难说啊 straight-draw+apair，flush draw，2 pair，set都有可能 如果是2对、3条、同时抽顺子跟同花其中之一的话，hero都落后了 如果没有其他信息帮助判断的话，我倾向于fold
当然，我是新手，召唤大侠来解释下
