WPN, $12 Buy-in (10/20 blinds) No Limit Hold'em Tournament, 2 Players
Poker Tools Powered By Holdem Manager - The Ultimate Poker Software Suite.

BB: 500 (25 bb)
Hero (SB): 500 (25 bb)

Preflop: Hero is SB with Q 9
Hero raises to 40, BB raises to 60, Hero calls 20

Hard for me to give him a range here but I guess any 2 broadways, Ax, mid SCs and mid-high pairs are a good first estimate.

Flop: (120) 5 Q 9 (2 players)
BB checks, Hero bets 80, BB calls 80

With top 2, I don't mind much hands besides pocket fives but that setup would be okay for me then.
 

Turn: (280) 6 (2 players)
BB checks, Hero checks

I think here is one first mistake: I should have bet and I should have sized it to something like 180-220 so that I can't get away like all those QxYh hands or combodraws that intend to checkshove turn
 

River: (280) 7 (2 players)
BB checks, Hero checks

I don't know what I'm doing here, I guess I have lost focus. As played with given board development I can't see any hands to extract value from

Results: 280 pot
Final Board: 5 Q 9 6 7
BB mucked and lost (-140 net)
Hero showed Q 9 and won 280 (140 net)
