On a tournament where the blind was 125/250, and all ante 210. I was the SB.
UTG raised to 500, 4 players folded. I raised to 750, the BB folded. The UTG called.

On the flop the board was 2-10-7, with the former two were diamond. We both checked on flop .

On the turn it was a J with diamond. Despite I hit a top two pair, I still checked on the turn and so did the UTG.

On the river it was a 5, an irrelevant card. I bet 250. The UTG raised with all in. Assuming he was trying to polarise his hand with a great possibility of bluff, I called and I was eliminated.

Much appreciation if you could point out whether I did anything wrong in this hand and which area can I improve.

P.S. I was automatically switched to this table and I didn't have too much information on my opponents in this table. Previously he was on UTG + 1 and won the hand by raising 500 on preflop.
