Thanks guys, im reviewing all of my JJ/TT/99 hands and finding that im 3betting alot sometimes in multiway pots. Next session ill get to work on playing these hands in a less crazy way. Also ive made myself a note 'bet/FOLD' I know what it means. Stacks you're right on with the KK i barely considered his range, pretty much just gave up with it.

Should I 3bet-shove preflop against a 20-40 bb shortstack with TT/JJ/QQ? There seems to be alot of shorties on ipoker 10nl

Things ill change
1. Stop 3betting TT/JJ so much maybe QQ too
2. Bet/FOLD when reraised with overcards. Think about outs!
3. Think about entire ranges in funny blind vs blind situations limp/donk bets with overcard/flushdraw/straightdraw on the flop

Cheers for taking the time to reply hangchiong and xXStacksXx you have given me alot to think about.
