Hi guys,

This spot came up when  there were 90 people left out of 470 in the tournament, blinds were (4k-8k/500ante) on 9 handed tables.

I was down to 10BB when CO limped and i shoved with A7 got called from the Big Blind holding AQ.  I got lucky and hit a flush on the turn and doubled up to 195K in chips.

The next hand UTG+2 (290K) opens to 20K and it folds to me where i have 77 and i flat call so we go heads up.  The information i had so far for this specific player was that he was TAG and did not show too many hands at showdown.  The range i gave him pre-flop was 55+, A9s+, KTs+, QTs+, JTs, ATo+, KJo+ 

             Equity   Win       Tie
UTG+2 53.23% 52.71% 0.53% { 55+, A9s+, KTs+, QTs+, JTs, ATo+, KJo+ }
CO       46.77% 46.24% 0.53% { 77 }

Flop comes 832.  Pot is 56500.  UTG+2 bets 31K and i Call leaving my self with 144K.

             Equity Win Tie
UTG+2 42.08% 41.79% 0.28% { 55+, A9s+, KTs+, QTs+, JTs, ATo+, KJo+ }
CO       57.92% 57.64% 0.28% { 77 }

Turn 6.  Pot is 118500.  UTG+2 Bets 50K and i Call leaving my self with 94K.

             Equity Win Tie
UTG+2 36.05% 35.75% 0.30% { 55+, A9s+, KTs+, QTs+, JTs, ATo+, KJo+ }
CO       63.95% 63.64% 0.30% { 77 }

River 9.  Pot is 218500.  UTG+2 All in.  I called for my tournament life.

             Equity Win Tie
UTG+2 26.40% 26.09% 0.31% { 55+, A9s+, KTs+, QTs+, JTs, ATo+, KJo+ }
CO       73.60% 73.29% 0.31% { 77 }

I will give some insight on how i was thinking throughout the hand.  When he opened pre-flop and folded to me i thought i had 2 options (raising/calling) so i called because that was the best approach with the information i had at the time.  

When the flop came and he bet 31K i thought that it was a safe flop for me and it missed a lot of his opening range but i didn’t want to raise him because i would be able to keep all of his semi bluffs and bluffs in his range.

The turn comes and its another safe card for me again but his second barrel seems a little bit strong but a little bit suspicious too because my range of hands calling him are sets and pocket pairs.  All my diamond draws will be raising on the flop.

On the river he goes all in and that is what made me lean towards  a call for a couple of reasons.  Firstly the board hits my range so hard that his All In pretty much polarizes his range to nutted hands Sets + or busted flush draws like 

AdK,AdQ,KdQ,AdJ,KdJ,QdJ,AdT,KdT,QdT,JdT,Ad9  and i do not see him moving All In with his over pairs because he will only get called from better in that spot.

I never make calls like that especially on the river for my tournament life but based on the reads and the way my opponent played his hand i came to the conclusion that i was good.

I would appreciate it if somebody could help me with this spot and advice me if i could take any other line at any point in the hand.

Also it is my first time using Equilab and wanted to ask you if i should deduct the hands that would never bet on the flop turn and river from his range to get an accurate result.

Thanks!
