Let's say there's a 5% rake and no rake cap (just to keep this simple). Five players are dealt in. Each player posts $4 ante, one player posts some small blind, and another player posts some big blind. The first three players fold (as their first action), and then both the SB player and the BB player go all-in for $50. The pot contains 5 * $4 + 2 * $50 = $120 now.
Is the rake then $6 = 0.05 * $120, or is it $5 = 0.05 * $100. In other words, are the antes included in the rake calculation?
