This is from another forum. Here's the summary.
On a board of 8-7-4 rainbow, player A silently bets 7,000, a 5k chip and two 1k chips. Player B silently bets 16,000, a 10k chip, a 5k chip, and a 1k chip. The dealer announces "Raise", and player B immediately objects, and said he was trying to call. The floor reduced his raise to a minraise, and player A called. On the turn (Q), player A bet, player B went all-in, and player A called. Player A had K-K, and Player B had 6-5 for the nut straight, so player B's raise was probably not an accident. Is player B's comment acceptable, or should he be penalized?
