Poker Ethics Question

[Jeepzeke]

FYI-I posted this in another forum. I am not sure of the correct forum for this.

Situation: 8 players left in 10 player sit in go. Small stack goes all in for about $300. I call and so does another (we each have about $1500). On the flop I hit top pair with Ace kicker, and bet. The other caller, who was on a straight draw, says I should not have bet because the idea is to eliminate players and it is easier to eliminate the all in with two hands competing compared to one.

I do see his point, but my thinking is I should build my chips with the best hand. If I dont bet and he hits his draw I do not get the all in money.

Also I have always heard you check an all in unless the board improves your hand.

Was I in the wrong here? If so, why? This was debated in the room and I was in the minority. BTW- I won the hand even though the straight draw called.

Thanks in advnace for your thoughts.
