Playing 3/6 and got akos on sb. Co raise 4xbb to 24.I 3bet to 72. Flop come 3T8r. I bet 52. Co raise to 150.
How??

Hand 2
I got 99 stack 768 on the sb and raise to 18 on a 3/6.. utg+1 stack 3229 and mp called. Flop come 3 2 7r. I bet 44 into 66, utg+1 raise to 170, mp fold, i raise to 270, and utg1 call. Turn come a 7, here i know he cannot have a 7 there, and i jam all in 400+..... i expect an overpair to fold with my play.

Please advice how could i do better? Or can this be avoided

Hi guys, i would like to seek for advice on this again.
I have been a low-mid stakes MtT player for the pass 3weeks.
I switch to MtT after playing recreationally in CG live n online for the pass 8 years.

For the pass 3 weeks i ended up in the icm for 14% of estimate MtTs i played.
I realised i tend to be confident at the early stage.
But when already in the icm, when the blinds already high, i tend to be lost.

Its a mix of making a wrong decision to call and others call me losing a flip.
Most of the time, i reached this stage ranking the top 10%-20%.
But always losing 2 - 3 pots and ending my journey.

Am i having a wrong strategy during this mid stage? There has to be something which i did wrong i guess. I think its a mix feeling of losing chips being temporary chip lead advantage and also “flipping witha short stack woundn’t end my journey” mindset.

Hope experts could advice, what should my focus on during this stage, vs big stack and shorter stack, etc.
Thanks

Dear pros,
Have been playing live games for many years recreationally
Recently i want to swap to online MTT professionally.

After a week of play, i realise i am always busted out during mid to mid late timing.
I would say normally after late registration ends.

Sometimes i can climb all the way up to 1st in position and i still lose out before im ITM.
Most of the time i climb up to top 10% of the pool in early games and later not able to sustain, slowly bleed away my chips most of the time.

My id is cat.moc and i play in PS.
Im quite sure there must be something wrong in me or i did badly in to always being eliminated around that same period of a tournament.

I dont know if i played too tight, too little bluff and steal or what.

Please advice, would also appreciate if can recommend me on where to go for some reviews and reading since i already have a feel and experience of MTT.

Thank you.
